Carbon dioxide adsorption battery, charge and discharge device, and carbon dioxide concentration device The present invention relates to a carbon dioxide adsorption battery, a charge and discharge device, and a carbon dioxide concentration device. Carbon dioxide is not only a substance widely present on the earth, accounting for about 0.04% of the atmosphere, but is also widely used in industry. As methods of using carbon dioxide, for example, foaming gases such as carbonated beverages, bath agents, and fire extinguishers, dry ice used for cooling, etc., and emergency supplementary air for bicycle tires, etc. can be cited. Also, carbon dioxide can be used as an extraction solvent for extracting caffeine, etc. by becoming a supercritical state. Also, carbon dioxide gas lasers used in lasers for processing in the industrial field or medical laser scalpels, etc. also use carbon dioxide. Furthermore, carbon dioxide is also used as a refrigerant for compressors instead of chlorofluorocarbon refrigerants. Also, in the agricultural field, carbon dioxide is also used, for example, for carbon dioxide fertilization to accelerate the growth of plants such as strawberries in forced cultivation and aquatic plants in ornamental water tanks. Also, CA (Controlled Atmosphere) storage of fresh agricultural products also uses carbon dioxide. As described above, since carbon dioxide is used in various fields, a method for obtaining carbon dioxide by separating carbon dioxide from a gas containing carbon dioxide such as air is required. Also, carbon dioxide is a causative substance of global warming. From this viewpoint, it is necessary to separate carbon dioxide from a gas containing carbon dioxide and utilize carbon dioxide. In order to utilize carbon dioxide, it is necessary to develop, for example, a method for separating carbon dioxide from a gas containing carbon dioxide, a device for adsorbing and separating carbon dioxide, and a device for utilizing carbon dioxide. As a method for separating carbon dioxide from a mixed gas containing oxygen and carbon dioxide such as air, various methods can be proposed. As such a separation method, for example, a method of adsorbing carbon dioxide in the air using an adsorbent for carbon dioxide, and then separating carbon dioxide from the air by desorbing the carbon dioxide adsorbed on the adsorbent can be cited. As an adsorbent for adsorbing carbon dioxide, for example, activated carbon, amine-based solvents, and aqueous potassium carbonate solutions can be cited. Also, as a method for separating carbon dioxide using an adsorbent, more specifically, a pressure swing adsorption (PSA) method in which carbon dioxide is adsorbed on the adsorbent under high pressure and then the pressure is reduced to desorb carbon dioxide from the adsorbent can be cited. As an adsorbent used when separating carbon dioxide by this PSA method, the adsorbent described in Patent Document 1 can be cited. Patent Document 1 describes an adsorbent for carbon dioxide, which is a composition in which 2 to 80 equivalent% of the sodium ions of a sodium-containing aluminosilicate are ion-exchanged with barium ions. According to Patent Document 1, an adsorbent with a large absorption capacity can be provided even under conditions of a high selectivity ratio for carbon dioxide and a large amount of moisture. Further, Patent Document 1 discloses that this adsorbent can be appropriately used for separating and concentrating carbon dioxide by the PSA method. Examples of devices for adsorbing and separating carbon dioxide include, for example, the acid gas adsorption and desorption element (device) described in Patent Document 2 and the carbon dioxide separation device described in Patent Document 3. Patent Document 2 describes an acid gas adsorption and desorption element, which has an acid gas adsorption and desorption layer containing a compound capable of adsorbing and desorbing acid gases such as carbon dioxide by oxidation and reduction and a substrate, and a pair of electrodes sandwiching the acid gas adsorption and desorption layer. Patent Document 3 describes a carbon dioxide separation device, which includes an electrolyte layer, a pair of electrodes sandwiching the electrolyte layer and provided on the electrolyte layer, and a voltage application unit for applying a voltage between the pair of electrodes. Each of the pair of electrodes is an electrode through which gas can pass. The electrolyte layer includes an electrolytic solution capable of dissolving carbon dioxide and a redox compound having an N-oxy radical in the molecule. Examples of devices using carbon dioxide include, for example, the batteries described in Non-Patent Document 1 and Non-Patent Document 2. Non-Patent Document 1 proposes a battery that is charged while absorbing carbon dioxide as a method of using carbon dioxide. Non-Patent Document 2 proposes a carbon dioxide rechargeable battery incorporating a redox system. Specifically, a carbon dioxide rechargeable battery using poly-1,4-anthraquinone and polyvinylferrocene for the negative electrode and the positive electrode, respectively, is proposed. Examples of devices using carbon dioxide include secondary batteries that not only use carbon dioxide but also concentrate carbon dioxide by adsorbing and desorbing carbon dioxide. Examples of the aforementioned secondary batteries include, for example, the carbon dioxide adsorption battery described in Patent Document 4. Patent Document 4 describes a carbon dioxide adsorption battery, which includes a positive electrode, a negative electrode, a separator disposed between the positive electrode and the negative electrode, and electrolyte layers respectively disposed between the positive electrode and the separator and between the negative electrode and the separator. The positive electrode is an electrode through which gas can pass. The electrolyte layer includes an electrolytic solution capable of dissolving carbon dioxide and a redox compound having an N-oxy radical in the molecule. The separator inhibits the passage of the redox compound and allows the electrolytic solution to pass through. In a device that can utilize carbon dioxide, it is necessary to utilize carbon dioxide more effectively and separate carbon dioxide from a gas containing carbon dioxide more efficiently. That is, in the device that can utilize carbon dioxide as described above, it is necessary to perform the adsorption and desorption of carbon dioxide more efficiently.

The above and other objects, features, and advantages of the present invention will become apparent from the following detailed description and the accompanying drawings. Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to these. [Carbon Dioxide Adsorption Battery] The carbon dioxide adsorption battery 10 according to the first embodiment of the present invention, as shown in FIGS. 1 to 4, includes a pair of electrodes 11, 12 (a first electrode 11 and a second electrode 12), a separator 18 disposed between the pair of electrodes 11, 12, electrolytes 13, 14 (a first electrolyte 13 and a second electrolyte 14) respectively disposed between the pair of electrodes 11, 12 and the separator 18, and a pair of flow paths 15, 16 (a first flow path 15 and a second flow path 16) respectively connected to the pair of electrodes 11, 12. That is, the carbon dioxide adsorption battery 10 includes a separator 18, electrolytes 13, 14 disposed on both sides of the separator 18, a pair of electrodes 11, 12 sandwiching the electrolytes 13, 14 and disposed on the electrolytes 13, 14, and a pair of flow paths 15, 16 respectively connected to the pair of electrodes 11, 12. Each of the pair of electrodes 11, 12 is a gas-permeable electrode. The electrolytes 13, 14 are divided into the first electrolyte 13 and the second electrolyte 14 by the separator 18 to form a pair of electrolytes 13, 14. Each of the electrolytes constituting the first electrolyte 13 and the second electrolyte 14 includes an electrolyte solution capable of dissolving carbon dioxide and a compound capable of electrochemically adsorbing and desorbing carbon dioxide. Further, in the pair of electrodes 11, 12, the first electrode 11 is disposed on the first electrolyte 13, and the second electrode 12 is disposed on the second electrolyte 14. Further, in the pair of flow paths 15, 16, the first electrode 11 is connected to the first flow path 15, and the second electrode 12 is connected to the second flow path 16. The pair of electrodes 11 and 12 are each gas-permeable electrodes. Specifically, the first electrode 11 allows the gas flowing through the first flow path 15 to pass through and come into contact with the first electrolyte 13. Also, the first electrode 11 allows the gas released from the first electrolyte 13 to pass through and be released into the first flow path 15. Further, the second electrode 12 allows the gas flowing through the second flow path 16 to pass through and come into contact with the second electrolyte 14. Also, the second electrode 12 allows the gas released from the second electrolyte 14 to pass through and be released into the first flow path 15. The pair of electrodes 11 and 12, as described above, allow the gases present around each electrode to pass through respectively. Also, the electrolytes 13 and 14 contain an electrolyte solution capable of dissolving carbon dioxide and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction. The separator 18 inhibits the passage of the compound and allows the electrolyte solution to pass through. That is, the separator 18 makes it more difficult for the compound to pass through than the electrolyte solution. Also, although the separator 18 is capable of passing the electrolyte solution, it is preferably one that does not allow the compound to pass through. The flow paths 15 and 16 are not particularly limited as long as they are flow paths capable of flowing gas. Also, the pair of flow paths 15 and 16 may be provided with valves 31, 32, 33, and 34 as needed. Specifically, the flow path 15 may be provided with the valve 33 on the upstream side and may be provided with the valve 34 on the downstream side. Also, the flow path 16 may be provided with the valve 31 on the upstream side and may be provided with the valve 32 on the downstream side. Furthermore, in FIGS. 1 to 4, only the valves that are shown closed and restrict the flow of gas are illustrated as the valves 31, 32, 33, and 34. The valves 31, 32, 33, and 34 are not particularly limited as long as they can restrict the flow of gas in the pair of flow paths 15 and 16. Furthermore, FIG. 1 is a schematic cross-sectional view showing an example of the configuration during charging in a carbon dioxide adsorption battery according to the first embodiment of the present invention. FIG. 2 is a schematic cross-sectional view showing an example of the configuration during discharging in a carbon dioxide adsorption battery according to the first embodiment of the present invention. FIG. 3 is a schematic cross-sectional view showing another example of the configuration during charging in a carbon dioxide adsorption battery according to the first embodiment of the present invention (an example of the configuration during charging according to the charging electrodes inverted from those shown in FIG. 1). FIG. 4 is a schematic cross-sectional view showing another example of the configuration during discharging in a carbon dioxide adsorption battery according to the first embodiment of the present invention (an example of the configuration during discharging after charging according to the charging electrodes inverted from those shown in FIG. 1). Regarding the aforementioned carbon dioxide adsorption battery 10, first, when a gas containing carbon dioxide flows through the aforementioned first flow path 15, the gas passes through the aforementioned first electrode 11 and contacts the aforementioned first electrolyte 13. As described above, since the aforementioned first electrolyte 13 contains an electrolyte solution capable of dissolving carbon dioxide, the carbon dioxide contained in the gas contacting the aforementioned first electrolyte 13 is dissolved in the aforementioned first electrolyte 13. Furthermore, as the gas containing carbon dioxide, as long as it contains carbon dioxide, there is no particular limitation, and examples thereof include a gas containing carbon dioxide and nitrogen, and more specifically, air and the like. In the aforementioned situation of the aforementioned carbon dioxide adsorption battery 10, as shown in FIG. 1, a voltage is applied between the aforementioned pair of electrodes 11 and 12 such that the potential of the aforementioned first electrode 11 becomes lower than the potential of the aforementioned second electrode 12. The application of the voltage for charging the aforementioned carbon dioxide adsorption battery 10, for example, as shown in FIG. 1, can also be performed by an application unit 21 that applies a voltage between the aforementioned pair of electrodes 11 and 12 such that the potential of the aforementioned first electrode 11 is lower than the potential of the aforementioned second electrode 12. When the voltage is applied as described above, the aforementioned compound contained in the aforementioned first electrolyte 13 becomes in a state capable of adsorbing carbon dioxide through an electrochemical reaction. That is, the voltage that makes the potential of the aforementioned first electrode 11 lower than the potential of the aforementioned second electrode 12 is the voltage that makes the aforementioned compound in a state capable of adsorbing carbon dioxide through an electrochemical reaction. Therefore, the aforementioned compound contained in the aforementioned first electrolyte 13 adsorbs the carbon dioxide dissolved in the aforementioned first electrolyte 13. Since the aforementioned compound that adsorbs carbon dioxide is not easily transferred to the side of the aforementioned second electrolyte 14 by the aforementioned separator 18, when the aforementioned compound adsorbs the aforementioned carbon dioxide, the aforementioned carbon dioxide adsorption battery 10 is in a charged state. Furthermore, since the carbon dioxide dissolved in the aforementioned electrolyte solution is adsorbed by the aforementioned compound, the dissolution of carbon dioxide in the aforementioned electrolyte solution is promoted, and the aforementioned carbon dioxide adsorption battery 10 appropriately proceeds to the charged state. Also, regarding the aforementioned carbon dioxide adsorption battery 10, as described above, since the aforementioned compound does not easily pass through the aforementioned separator 18, even if the application of the voltage between the aforementioned pair of electrodes 11 and 12 is stopped, as long as the aforementioned pair of electrodes 11 and 12 are not electrically connected to discharge, the state where carbon dioxide is adsorbed by the aforementioned compound, that is, the charged state, can be appropriately maintained. The application of the voltage for charging the aforementioned carbon dioxide adsorption battery 10 is not particularly limited as long as the voltage as described above can be applied. At this time, since there is no gas flow in the aforementioned second flow path 16, both the aforementioned valve 31 on the upstream side and the aforementioned valve 32 on the downstream side of the aforementioned second flow path 16 can be closed. Thereafter, in the aforementioned carbon dioxide adsorption battery 10, discharge is performed by electrically connecting the pair of electrodes 11 and 12. Specifically, as the discharge of the aforementioned carbon dioxide adsorption battery 10, as shown in FIG. 2, discharge can also be performed by electrically connecting the pair of electrodes 11 and 12 by providing a resistor 22 between the pair of electrodes 11 and 12. In this case, the state in which the aforementioned compound adsorbs carbon dioxide can be eliminated by an electrochemical reaction, and the carbon dioxide adsorbed on the aforementioned compound desorbs from the aforementioned compound. Therefore, in the aforementioned carbon dioxide adsorption battery 10, carbon dioxide is released from the aforementioned first electrode 11 to the aforementioned first flow path 15 during discharge. The gas released from the aforementioned carbon dioxide adsorption battery 10 during discharge is the gas that was adsorbed on the aforementioned compound in the aforementioned carbon dioxide adsorption battery 10 during charging. That is, it becomes mainly carbon dioxide, so it is a gas with a very high carbon dioxide concentration. From this viewpoint, the aforementioned carbon dioxide adsorption battery 10 can concentrate carbon dioxide. Additionally, at this time, since there is no gas flow in the aforementioned second flow path 16 during charging, the aforementioned valve 31 on the upstream side and the aforementioned valve 32 on the downstream side of the aforementioned second flow path 16 can both be closed. Furthermore, since carbon dioxide is released in the aforementioned first flow path 15, in order to prevent the backflow of carbon dioxide, it is preferable to close the aforementioned valve 33 on the upstream side of the aforementioned first flow path 15. As shown in FIG. 3, the aforementioned carbon dioxide adsorption battery 10 is in a state where a gas containing carbon dioxide flows through the aforementioned second flow path 16. Even by making the potential of the aforementioned second electrode 12 lower than the potential of the aforementioned first electrode 11 and applying a voltage between the pair of electrodes 11 and 12, charging can be performed. That is, the aforementioned carbon dioxide adsorption battery 10 can be charged even when the electrodes are reversed and a voltage is applied. In the aforementioned carbon dioxide adsorption battery 10, when a gas containing carbon dioxide flows through the aforementioned second flow path 16, the gas passes through the aforementioned second electrode 12 and contacts the aforementioned second electrolyte 14. Since the aforementioned second electrolyte 14, like the aforementioned first electrolyte 13, contains an electrolyte solution capable of dissolving carbon dioxide, the carbon dioxide contained in the gas contacting the aforementioned second electrolyte 14 is dissolved in the aforementioned second electrolyte 14. In the aforementioned carbon dioxide adsorption battery 10, as described above, the potential of the aforementioned second electrode 12 is made lower than the potential of the aforementioned first electrode 11, and a voltage is applied between the pair of electrodes 11 and 12. The application of voltage for charging the aforementioned carbon dioxide adsorption battery 10 can be carried out, for example, as shown in FIG. 3, by an application unit 23 that makes the potential of the aforementioned second electrode 12 lower than the potential of the aforementioned first electrode 11 and applies a voltage between the pair of electrodes 11 and 12. The aforementioned application unit 21 and the aforementioned application unit 23 can also be voltage application units capable of switching the high and low of the potentials of the pair of electrodes 11 and 12. If the voltage is applied as described above, the aforementioned compound contained in the aforementioned second electrolyte 14 becomes in a state capable of adsorbing carbon dioxide through an electrochemical reaction. Therefore, the aforementioned compound contained in the aforementioned second electrolyte 14 adsorbs the carbon dioxide dissolved in the aforementioned second electrolyte 14, and the aforementioned carbon dioxide adsorption battery 10 becomes in a charged state. Additionally, at this time, since there is no gas flow in the aforementioned first flow path 15, the aforementioned valve 33 on the upstream side and the aforementioned valve 34 on the downstream side of the aforementioned first flow path 15 can both be closed. After that, in the aforementioned carbon dioxide adsorption battery 10, the pair of electrodes 11 and 12 are electrically connected to discharge. Specifically, as the discharge of the aforementioned carbon dioxide adsorption battery 10, as shown in FIG. 4, for example, a resistor 22 is provided between the pair of electrodes 11 and 12, and the pair of electrodes 11 and 12 are electrically connected to discharge. If so, the carbon dioxide adsorbed on the aforementioned compound desorbs from the aforementioned compound, and carbon dioxide is released from the aforementioned second electrode 12 to the aforementioned second flow path 16. Furthermore, at this time, since there is no gas flow in the aforementioned first flow path 15 as in the case of charging, the aforementioned valve 33 on the upstream side and the aforementioned valve 34 on the downstream side of the aforementioned first flow path 15 can both be closed. Moreover, since carbon dioxide is released in the aforementioned second flow path 16, in order to prevent the reverse flow of carbon dioxide, it is preferably to close the aforementioned valve 31 on the upstream side of the aforementioned second flow path 16. In the above-described carbon dioxide adsorption battery 10, when a voltage is applied across the pair of electrodes 11 and 12, charging occurs while carbon dioxide is adsorbed onto the aforementioned compound. When the electrodes are electrically connected to discharge, the carbon dioxide adsorbed onto the compound desorbs from the compound. In the carbon dioxide adsorption battery 10, when a voltage is applied across the pair of electrodes 11 and 12 such that the potential of the first electrode 11 becomes lower than that of the second electrode 12, carbon dioxide is introduced from the first flow path 15 connected to the first electrode 11 into the first electrolyte 13 and adsorbed onto the compound. Also, when a voltage is applied across the pair of electrodes 11 and 12 such that the potential of the first electrode 11 becomes higher than that of the second electrode 12, carbon dioxide is introduced from the second flow path 16 connected to the second electrode 12 into the second electrolyte 14 and adsorbed onto the compound. As described above, in the carbon dioxide adsorption battery 10, in the case of charging as shown in FIG. 1, the first electrode 11 becomes the electrode on the side where carbon dioxide is introduced from the gas containing carbon dioxide, and in the case of discharging as shown in FIG. 2, it becomes the electrode on the side where the carbon dioxide introduced during charging is released. Also, as described above, in the carbon dioxide adsorption battery 10, in the case of charging as shown in FIG. 3, the second electrode 12 becomes the electrode on the side where carbon dioxide is introduced from the gas containing carbon dioxide, and in the case of discharging as shown in FIG. 4, it becomes the electrode on the side where the carbon dioxide introduced during charging is released. That is, in the carbon dioxide adsorption battery 10, the pair of electrodes 11 and 12 includes the first electrode 11 and the second electrode 12. Based on the above, in the carbon dioxide adsorption battery 10, carbon dioxide adsorption and desorption can be performed from either the first electrode 11 or the second electrode 12. Therefore, the carbon dioxide adsorption battery 10 can efficiently adsorb carbon dioxide from the gas containing carbon dioxide while charging, and desorb the carbon dioxide during discharge. Also, regardless of whether it is from the first electrode 11 side or the second electrode 12 side, the deviation in the usage frequency of each electrode is reduced by performing carbon dioxide adsorption and desorption, so the durability of the electrode can be extended. Also, in the carbon dioxide adsorption battery 10, since the adsorption and desorption of carbon dioxide are performed by applying a voltage, it can be carried out regardless of the surrounding environment such as temperature or atmospheric pressure. The carbon dioxide adsorption battery 10, for example, can perform carbon dioxide adsorption and desorption regardless of whether it is at room temperature or under atmospheric pressure. As described above, even without discharging, the aforementioned carbon dioxide adsorption battery 10 can adsorb carbon dioxide from a gas containing carbon dioxide while charging by reversing the electrodes and applying a voltage, as shown in FIGS. 5 and 6, and can desorb the aforementioned carbon dioxide during discharging. In addition, FIG. 5 is a schematic cross-sectional view showing an example of the configuration during charging before the reversal of the electrodes in the carbon dioxide adsorption battery according to the first embodiment of the present invention. FIG. 6 is a schematic cross-sectional view showing an example of the configuration during charging after the reversal of the electrodes (the reversal is from the electrodes during charging shown in FIG. 5) in the carbon dioxide adsorption battery according to the first embodiment of the present invention. As shown in FIG. 5, in the aforementioned carbon dioxide adsorption battery 10, if the potential of the aforementioned first electrode 11 is made lower than the potential of the aforementioned second electrode 12 by the aforementioned application unit 21 and a voltage is applied between the aforementioned pair of electrodes 11 and 12, carbon dioxide is adsorbed from the gas flowing through the aforementioned first flow path 15 onto the aforementioned compound contained in the aforementioned first electrolyte 13. Therefore, the aforementioned carbon dioxide adsorption battery 10 can adsorb carbon dioxide from the gas containing carbon dioxide flowing through the aforementioned first flow path 15 while charging. If this charging is the initial charging, that is, before this charging, as long as carbon dioxide is not adsorbed onto the aforementioned compound contained in the aforementioned second electrolyte 14, it is only to adsorb carbon dioxide from the gas containing carbon dioxide while charging. After that, as shown in FIG. 6, in the aforementioned carbon dioxide adsorption battery 10, if the potential of the aforementioned second electrode 12 is made lower than the potential of the aforementioned first electrode 11 by the aforementioned application unit 23 and a voltage is applied between the aforementioned pair of electrodes 11 and 12, the carbon dioxide adsorbed onto the aforementioned compound contained in the aforementioned first electrolyte 13 desorbs, and the carbon dioxide is released into the aforementioned first flow path 15. As the aforementioned carbon dioxide is released into the aforementioned first flow path 15, at the same time, carbon dioxide is adsorbed from the gas flowing through the aforementioned second flow path 16 onto the aforementioned compound contained in the aforementioned first electrolyte 13. Therefore, the aforementioned carbon dioxide adsorption battery 10 releases carbon dioxide into the aforementioned first flow path 15 and can adsorb carbon dioxide from the gas containing carbon dioxide flowing through the aforementioned second flow path 16 while charging. In addition, at this time, since carbon dioxide is released in the aforementioned first flow path 15, in order to prevent the reverse flow of carbon dioxide, it is preferable to close the aforementioned valve 33 on the upstream side of the aforementioned first flow path 15. Thereafter, for the aforementioned carbon dioxide adsorption battery 10, as shown in FIG. 5, if the potential of the aforementioned first electrode 11 is made lower than the potential of the aforementioned second electrode 12 by the aforementioned application unit 21 and a voltage is applied between the pair of electrodes 11 and 12, the carbon dioxide adsorbed to the aforementioned compound contained in the aforementioned second electrolyte 14 is desorbed, and the carbon dioxide is released into the aforementioned second flow path 16. As the aforementioned carbon dioxide is released into the aforementioned second flow path 16, at the same time, the carbon dioxide in the gas flowing through the aforementioned first flow path 15 is adsorbed to the aforementioned compound contained in the aforementioned second electrolyte 14. Therefore, the aforementioned carbon dioxide adsorption battery 10 discharges carbon dioxide into the aforementioned second flow path 16, and at the same time, can adsorb carbon dioxide from the gas containing carbon dioxide flowing through the aforementioned first flow path 15 and perform charging simultaneously. In addition, at this time, since carbon dioxide is released in the aforementioned second flow path 16, in order to prevent the backflow of carbon dioxide, it is preferable to close the aforementioned valve 31 on the upstream side of the aforementioned second flow path 16. Also, the aforementioned application unit 21 and the aforementioned application unit 23 may be voltage application units capable of switching the levels of the potentials of the pair of electrodes 11 and 12. According to the foregoing, for the aforementioned carbon dioxide adsorption battery 10, even without discharging, as shown in FIGS. 5 and 6, by reversing the electrodes and applying a voltage, the adsorption and desorption of carbon dioxide can be performed from either the aforementioned first electrode 11 or the aforementioned second electrode 12, and furthermore, the adsorption and desorption of carbon dioxide can be continuously performed for each of the aforementioned first electrode 11 and the aforementioned second electrode 12. Therefore, as shown in FIGS. 5 and 6, the aforementioned carbon dioxide adsorption battery 10 can efficiently adsorb carbon dioxide from the gas containing carbon dioxide and perform charging by reversing the electrodes and applying a voltage, and desorb the aforementioned carbon dioxide during discharge. Specifically, the concentration efficiency of carbon dioxide per unit time can be improved. As described above, for the aforementioned carbon dioxide adsorption battery 10, as shown in FIGS. 5 and 6, by reversing the electrodes and applying a voltage, the adsorption and desorption of carbon dioxide can be continuously performed for each of the aforementioned first electrode 11 and the aforementioned second electrode 12, and carbon dioxide can be efficiently concentrated. Therefore, the aforementioned carbon dioxide adsorption battery 10 can be a carbon dioxide concentration device capable of efficiently concentrating carbon dioxide by including a voltage application unit capable of switching the levels of the potentials of the pair of electrodes 11 and 12 as the aforementioned application unit 21 and the aforementioned application unit 23. That is, a carbon dioxide concentration device is obtained, which includes the aforementioned carbon dioxide adsorption battery 10, and application units 21 and 23 that apply a voltage between the pair of electrodes 11 and 12, and the application units 21 and 23 can switch the levels of the potentials of the pair of electrodes 11 and 12. (A pair of electrodes) Each of the electrodes constituting the aforementioned pair of electrodes 11 and 12 is not particularly limited as long as it is an electrode through which gas can pass. That is, each of the aforementioned electrodes 11 and 12 only needs to be a conductive member that can pass gases such as carbon dioxide and can flow an electric current between the aforementioned electrolytes 13 and 14 with the aforementioned pair of electrodes 11 and 12 interposed therebetween. Further, as each of the aforementioned electrodes 11 and 12, it is preferably a porous body having conductivity to such an extent that it does not impede electron movement, can store electric charges, has excellent gas permeability, and has a wide gas contact area. Specifically, as each of the aforementioned electrodes 11 and 12, examples include electrodes made of a porous conductive material and electrodes made of a porous body containing a conductive material. Examples of the aforementioned porous conductive material include, for example, a porous metal layer, a porous body containing metal fibers, a porous body containing conductive fibers, a porous body containing carbon as a main component, and a porous body containing carbon. Examples of the aforementioned carbon include, for example, activated carbon such as graphite, carbon nanotubes, activated carbon fibers, and carbonaceous materials such as carbon fibers. As the aforementioned porous body containing carbon, it is preferably one in which the aforementioned carbonaceous material is in the form of a cloth or felt. Examples of the aforementioned porous body containing metal fibers include a woven fabric containing metal fibers, a knitted fabric containing metal fibers, and a braided fabric containing metal fibers. Examples of the aforementioned porous body containing conductive fibers include a woven fabric containing conductive fibers, a knitted fabric containing conductive fibers, and a braided fabric containing conductive fibers. Examples of the aforementioned conductive fibers include, for example, fibers coated with a metal. Further, as the coating method, examples include plating. That is, examples of the aforementioned conductive fibers include, for example, plated fibers. The aforementioned porous conductive materials can be used alone or in combination of two or more. That is, each of the aforementioned electrodes 11 and 12 can be an electrode composed of a single conductive material among the aforementioned porous conductive materials, or can be an electrode composed of a combination of two or more conductive materials. Further, examples of the conductive material contained in the porous body include, for example, metal fibers, conductive fibers, metal particles, conductive ceramics, graphite, carbon nanotubes, activated carbon such as activated carbon fibers, and carbonaceous materials such as carbon fibers. Examples of the aforementioned metal fibers and the aforementioned metal particles include, for example, those containing copper and silver. The aforementioned porous body containing metal fibers can also be a porous conductive material. Further, as the aforementioned conductive material, graphite, carbon nanotubes, activated carbon, and carbon fibers are preferred, and activated carbon such as activated carbon fibers is more preferred from the viewpoints of corrosion resistance and specific surface area. Further, the aforementioned conductive materials can be used alone or in combination of two or more. Further, as each of the aforementioned electrodes 11 and 12, it is preferably a carbon-based electrode using activated carbon or carbon fibers, and an electrode with a high porosity using a needle-shaped conductive material. Specifically, as each of the aforementioned electrodes 11 and 12, examples include carbon flakes, carbon cloth, and carbon paper.Further, as the pair of electrodes 11 and 12, it is preferable that each of the above electrodes contains a conductive material including at least one selected from the group consisting of metal fibers, conductive fibers, metal particles, conductive ceramics, graphite, carbon nanotubes, activated carbon, and carbon fibers. If the electrodes are as described above, gas can be appropriately passed through, and a voltage can be appropriately applied between the pair of electrodes 11 and 12 using the above-described application units 21 and 23. Therefore, by using the above electrodes 11 and 12 as the pair of electrodes 11 and 12, a carbon dioxide adsorption battery can be obtained that can more appropriately adsorb carbon dioxide from a gas containing carbon dioxide during charging and can more appropriately release carbon dioxide during discharging. The porous metal layer is a metal layer having a plurality of pores formed therein. Further, from the viewpoint that the pores have excellent gas permeability, it is preferable that the porous metal layer is formed throughout the metal layer. Further, as a method for obtaining the porous metal layer, as long as it is a method (porousification method) of performing a process of forming a plurality of pores on a metal layer that does not have the pores formed therein (the metal layer before the pores are formed), there is no particular limitation. Examples of such a method include physical methods such as cutting, grinding, and sandblasting, and chemical methods such as electrolytic etching or electroless etching using an etching solution such as an acid or a base. Further, as the porousification method, each of the above methods can be performed alone, or two or more of them can be combined. Further, in order to make the formed pores (fine pores) denser (form denser pores), from the viewpoint of increasing the surface area, as the porousification method, a chemical method is preferable. Further, the material of the metal layer is not particularly limited, and examples thereof include aluminum, copper, silver, gold, iron, titanium, molybdenum, tungsten, nickel, and alloys thereof. From the viewpoints of price and workability, among them, aluminum is preferable as the material of the metal layer. Further, as the metal layer before the pores are formed, a so-called aluminum foil is preferable. The BET specific surface area of each of the electrodes 11 and 12 is not particularly limited, but for example: it is preferably 1 m 2 / g or more, more preferably 100 m 2 / g or more, and even more preferably 500 m 2 / g or more. From the viewpoint of gas permeability (ventilation), the BET specific surface area of each of the electrodes 11 and 12 is preferably large, but from the relationship such as the strength of each of the electrodes 11 and 12, it is preferably 3000 m 2 / g or less, more preferably 2500 m 2 / g or less, and even more preferably 2000 m 2 / g or less. Therefore, the BET specific surface area of each of the electrodes 11 and 12 is preferably 1 to 3000 m 2 / g, more preferably 100 to 2500 m 2 / g, even more preferably 500 to 2000 m 2 / g. If the BET specific surface area of each of the electrodes 11 and 12 is too small, the gas permeability (ventilation) decreases, and there is a tendency to hinder the permeation of carbon dioxide. Also, if the BET specific surface area of each of the electrodes 11 and 12 is too large, the strength of the electrode and the like tend to become insufficient. From these viewpoints, if the BET specific surface area of each of the electrodes 11 and 12 is within the above range, adsorption and release of carbon dioxide can be achieved over a long period, and it can be used as a carbon dioxide battery for a long time. In addition, the BET specific surface area is the specific surface area measured by the BET method, and can be measured by a well-known method. As a method for measuring the BET specific surface area, for example, a method of measuring a nitrogen adsorption isotherm and calculating from the obtained adsorption isotherm can be mentioned. As each of the electrodes 11 and 12, a current collector may be further provided. That is, each of the electrodes 11 and 12 may be one including the porous body, or may be one including the porous body and the current collector. As the current collector, there is no particular limitation as long as it is a current collector that does not hinder the permeation of the gas. As the current collector, for example, one made of a conductive material and having openings formed within a range that does not prevent gas passage can be used. More specifically, as the current collector, it may be one including metals such as mixed rare earth metals, stamped metals, and expanded metals, or may be one having conductivity by plating a woven fabric or non-woven fabric containing natural fibers or synthetic fibers. As the metals that can be used as the current collector, for example, stainless steel, iron, nickel, titanium, and copper can be used. In the electrode including the porous body and the current collector, it is preferable that the porous body and the current collector are integrated. As a method for integration, there is no particular limitation. The integrated porous body and current collector may be, for example, a method such as ultrasonic welding and plasma welding is used to partially integrate the porous body and the current collector and ensure conductivity. Also, the integrated porous body and current collector may be one in which the porous body and the current collector are sandwiched between a conductive material such as a conductive adhesive and have conductivity. As the conductive material, there is no particular limitation, and for example, those in which metal fine particles such as silver, gold, and nickel are dispersed, carbon material-based conductive materials, and conductive polymers can be used. As described above, the electrodes 11 and 12 are conductive members that can pass an electric current through the electrolytes 13 and 14 sandwiched between the pair of electrodes 11 and 12. The smaller the surface resistance value thereof, the better. For example, it is preferably 1 kΩ / sq or less, more preferably 200 Ω / sq or less. Also, for the surface resistance values of the electrodes 11 and 12, the smaller the better. In practice, with 1 Ω / sq as the limit, it mostly becomes about 10 Ω / sq or more. Therefore, the surface resistance values of the electrodes 11 and 12 are preferably 1 Ω / sq to 1 kΩ / sq, more preferably 10 to 200 Ω / sq. For electrodes with surface resistance values as described above, an electric current can be appropriately passed through the electrolytes 13 and 14, and carbon dioxide can be appropriately separated. The thicknesses of the electrodes 11 and 12 are not particularly limited, but are preferably such that they can adsorb carbon dioxide and can appropriately prevent leakage of the electrolytic solution. The thicknesses of the electrodes 11 and 12 are, for example, preferably 20 μm or more and 10 mm or less, more preferably 50 μm or more and 5 mm. If the electrodes 11 and 12 are too thin, there is a tendency that the strength of the electrodes and the like becomes insufficient. Also, if the electrodes 11 and 12 are too thick, there is a tendency that the gas permeability (ventilation property) decreases, hindering the permeation of carbon dioxide. From these viewpoints, if the thicknesses of the electrodes are within the above ranges, carbon dioxide separation can be achieved over a long period. The pair of electrodes (the first electrode 11 and the second electrode 12) are preferably arranged in a face-symmetric manner with respect to the separator 18 (symmetric with each other with the separator 18 as the center). By arranging as described above, the adsorption and desorption of carbon dioxide from the electrode side of either of the pair of electrodes caused by reversing the voltage applied between the pair of electrodes 11 and 12 can be performed more reliably. Also, even when the voltage applied between the pair of electrodes 11 and 12 is reversed, the same performance can be maintained before and after the reversal. Therefore, the adsorption of carbon dioxide from a gas containing carbon dioxide, charging, and desorption of the carbon dioxide during discharge can be performed more efficiently as described above. It is preferable to select the above electrodes 11 and 12 such that the performance difference (the performance difference before and after inversion) when inverting the voltage applied between the pair of electrodes 11 and 12 is reduced. Specifically, it is preferable that the electrode 11 and the electrode 12 are made of the same material. Also, from the viewpoint of reducing the performance difference when inverting the voltage applied between the pair of electrodes, for example, the ratio of the thickness of the electrode 11 to the thickness of the electrode 12 (thickness of electrode 11 / thickness of electrode 12) is preferably 0.9 to 1.1, more preferably 0.95 to 1.05, and even more preferably 1 (i.e., the same thickness). Also, the ratio of the BET specific surface area of the electrode 11 to the BET specific surface area of the electrode 12 (BET specific surface area of electrode 11 / BET specific surface area of electrode 12) is preferably 0.9 to 1.1, more preferably 0.95 to 1.05, and even more preferably 1 (the same BET specific surface area). As described above, it is preferable that the above electrodes 11 and 12 are of the same material and characteristics, and more preferably are the same electrodes individually. If the electrode 11 and the electrode 12 are of the same material, the performance difference when inverting the voltage applied between the pair of electrodes is reduced. (Electrolyte) Each electrolyte constituting the first electrolyte 13 and the second electrolyte 14 is not particularly limited as long as it contains an electrolytic solution capable of dissolving carbon dioxide and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction. The above electrolytes 13 and 14 may also be the same electrolyte. Specifically, since the above electrolytes 13 and 14 are divided into the first electrolyte 13 and the second electrolyte 14 by the above separation material 18, the above electrolytes 13 and 14 are the same electrolyte. Also, as described above, the above electrolytes 13 and 14 are carbon dioxide separation bodies that contribute to the separation of carbon dioxide by affecting the adsorption and release of carbon dioxide. The aforementioned compound is not particularly limited as long as it can adsorb and desorb carbon dioxide through an electrochemical reaction. Examples of the aforementioned compound include a compound that adsorbs carbon dioxide by undergoing electrolytic reduction and desorbs carbon dioxide by undergoing electrolytic oxidation. Also, examples of the aforementioned compound in the aforementioned carbon dioxide adsorption battery 10 include the following compounds. Specifically, examples include a compound that adsorbs carbon dioxide when the potential is relatively low and it accepts electrons between the pair of electrodes 11 and 12, and desorbs carbon dioxide when the potential is relatively high and it supplies electrons. More specifically, examples of the aforementioned compound include a redox compound. Also, examples of the aforementioned redox compound include a redox compound having an N-oxy radical in the molecule. Preferably, the aforementioned redox compound is, for example, a compound in which two quaternary carbons are bonded to the N-oxy radical. In the compound in which two quaternary carbons are bonded to the N-oxy radical, the N-oxy radical can inhibit the decomposition of the N-oxy radical by removing a hydrogen radical from the carbon adjacent to the N-oxy radical. Therefore, the aforementioned redox compound can more appropriately adsorb and desorb carbon dioxide, and the aforementioned carbon dioxide adsorption battery can further adsorb carbon dioxide from a gas containing carbon dioxide and can further maintain a charged state. The aforementioned redox compound is not particularly limited as long as it is a redox compound having an N-oxy radical in the molecule. Preferably, the aforementioned redox compound is non-volatile. As shown in the following formula (4) and the following formula (5), the aforementioned redox compound adsorbs carbon dioxide by undergoing electrolytic reduction, and as shown in the following formula (7) and the following formula (8), desorbs the adsorbed carbon dioxide by undergoing electrolytic oxidation. For example, the redox compound is such that, by the aforementioned application unit 21, when a voltage is applied between the pair of electrodes 11 and 12, the N-oxy radical is reduced to form an N-oxy anion radical, which bonds to carbon dioxide. Also, when the aforementioned carbon dioxide adsorption battery 10 discharges, carbon dioxide desorbs to form an N-oxy anion radical, and the N-oxy anion radical is oxidized to revert to the N-oxy radical. The aforementioned redox compound is, as described above, a compound in which the N-oxy radical undergoes a change through redox. The redox compound contained in each of the electrolytes 13 and 14 described above is the electrolyte on the electrode side with a lower potential among the pair of electrodes 11 and 12. As shown in the following formula (4), the N-oxy radical is reduced to form an N-oxy anion radical. Then, as shown in the following formula (5), carbon dioxide dissolved in the electrolyte binds to the N-oxy anion radical, thereby promoting the dissolution of carbon dioxide in the electrolyte. Therefore, in the carbon dioxide adsorption battery 10 during charging, carbon dioxide is introduced from the electrode side with a lower potential among the pair of electrodes 11 and 12, and carbon dioxide is adsorbed by the electrolyte on the electrode side. That is, the redox compound, as shown in the following formula (4) and the following formula (5), adsorbs carbon dioxide by undergoing electrolytic reduction. On the other hand, the redox compound contained in each of the electrolytes 13 and 14 described above is the electrolyte on the electrode side with a higher potential among the pair of electrodes 11 and 12. As shown in the following formula (6), the N-oxy radical is oxidized to form an N-oxy cation radical. Although the separator 18 allows the electrolyte to pass through, it inhibits the passage of the redox compound. That is, the redox compound is more difficult to pass through the separator 18 than the electrolyte. Therefore, whether the redox compound in which the N-oxy radical is reduced to form an N-oxy anion radical or the redox compound bound to carbon dioxide, it is difficult to pass through the separator 18. Therefore, even after charging is stopped, as long as discharging is not performed, since these redox compounds are difficult to pass through the separator 18, the carbon dioxide adsorption battery 10 can maintain the charged state. Next, when the charged carbon dioxide adsorption battery 10 is discharged, as shown in the following formula (7), during charging, in the electrolyte on the electrode side with a higher potential among the pair of electrodes 11 and 12, the N-oxy cation radical is restored to the N-oxy radical. During charging, in the electrolyte on the electrode side with a lower potential among the pair of electrodes 11 and 12, as shown in the following formula (8), carbon dioxide desorbs from the redox compound, and as shown in the following formula (9), the N-oxy anion radical is restored to the N-oxy radical. Therefore, during discharging, the carbon dioxide adsorption battery 10 can discharge carbon dioxide from the electrode side where carbon dioxide was introduced. As described above, in the aforementioned carbon dioxide adsorption battery 10, by containing the aforementioned redox compound in the aforementioned electrolytes 13 and 14, carbon dioxide can be adsorbed during charging, released during discharging, and carbon dioxide can be easily adsorbed from a gas containing carbon dioxide while charging is being carried out. Also, in the aforementioned carbon dioxide adsorption battery 10, carbon dioxide can be concentrated by the adsorption and release of carbon dioxide as described above. Further, in the aforementioned carbon dioxide adsorption battery 10, since a redox compound having an N-oxy radical in the molecule, which has higher durability than the aforementioned quinone compound, is used instead of the aforementioned quinone compound, when ionization occurs as in the case of quinone, the reactivity for dehydrogenation and the like from other substances is extremely low, and thus, the durability is also good. Also, when the electrolyte on one electrode side of the pair of electrodes contains a quinone compound, it is difficult to use it while containing it on the electrolyte on the other electrode side. On the other hand, as long as it is a redox compound having an N-oxy radical in the molecule, since the N-oxy radical becomes an N-oxy cation radical by oxidation, the same compound can be used on both of the aforementioned pair of electrodes. Therefore, as the aforementioned compound contained in the aforementioned electrolytes 13 and 14, there is also an advantage that it is not necessary to prepare several kinds of complicated compounds, and the number of components can be reduced. The aforementioned electrolyte is not particularly limited as long as it is an electrolyte capable of dissolving carbon dioxide, and it may be an electrolyte containing an electrolyte and a solvent, or may be an electrolyte containing an ionic liquid. In addition, the electrolyte capable of dissolving carbon dioxide only needs to be capable of dissolving carbon dioxide, that is, as long as it is an electrolyte capable of dissolving a trace amount of carbon dioxide, high solubility is not required. The reason for the above is as follows. In the carbon dioxide adsorption battery of the present embodiment, as described above, by the bonding and desorption of carbon dioxide to the aforementioned compound, the following mechanism is adopted: during charging, carbon dioxide is introduced into the aforementioned first electrolyte 13 on the aforementioned first electrode 11 side or the aforementioned second electrolyte 14 on the aforementioned second electrode 12 side, and during discharging, carbon dioxide is released from each of the aforementioned electrolytes 13 and 14 on the side where carbon dioxide was introduced during charging, and the adsorption and release of carbon dioxide are carried out. Therefore, as long as a trace amount of carbon dioxide is dissolved in the electrolyte contained in each of the aforementioned electrolytes 13 and 14, the adsorption and release of carbon dioxide are carried out. As described above, the aforementioned electrolyte is not particularly limited as long as it is an electrolyte capable of dissolving carbon dioxide, but it is preferably non-volatile. As described above, the aforementioned electrolyte may be an electrolyte containing an electrolyte and a solvent, or may be an electrolyte containing an ionic liquid, but it is preferably non-volatile and can be used as an electrolyte.

Also, when two or more of them are used in combination as the aforementioned solvent, from the viewpoint of dissolving carbon dioxide, it is preferable to use water.

Furthermore, as described above, the redox compound may also be a polymer compound, and examples thereof include compounds obtained by polymerizing the compounds represented by any one of the aforementioned formulas (1) to (3). Examples of the aforementioned polymer compound include compounds obtained by polymerizing monomers such as 4-acryloyloxy-2,2,6,6-tetramethylpiperidinyloxy radical, 4-methacryloyloxy-2,2,6,6-tetramethylpiperidinyloxy radical, 3-acryloyloxy-2,2,6,6-tetramethylpyrrolidinyloxy radical, 3-methacryloyloxy-2,2,6,6-tetramethylpyrrolidinyloxy radical, 4-vinyloyloxy-2,2,6,6-tetramethylpiperidinyloxy radical, and 4-vinyloyloxy-2,2,5,5-tetramethylpyrrolidinyloxy radical. Also, as the aforementioned polymer compound, it may be a compound obtained by polymerizing the aforementioned monomers alone, or may be a compound obtained by polymerizing a combination of two or more of the aforementioned monomers.

Among the aforementioned redox compounds and the compounds exemplified above, 1,4-bis(1-oxy-2,2,6,6-tetramethyl-1-piperidin-4-yloxy)xylene, 4-acetamido-2,2,6,6-tetramethylpiperidine 1-oxyl radical, and poly(4-methacryloyloxy-2,2,6,6-tetramethylpiperidinyloxy radical) are preferable. The aforementioned redox compound may be used alone or in combination of two or more. The compound represented by any one of the aforementioned formulas (1) to (3) may be a compound obtained by synthesis using a specified synthesis method or may be a commercially available product. As the aforementioned synthesis method, as long as it is a synthesis method for obtaining the compound represented by any one of the aforementioned formulas (1) to (3), there is no particular limitation, and examples thereof include a method of nitroxidation by oxidizing the amino group of a disubstituted amine compound. Furthermore, non-volatile means that at normal temperature and pressure, the substance does not evaporate or does not evaporate immediately. For example, in this specification, 2,2,6,6-tetramethylpiperidine 1-oxyl radical (TEMPO) is not non-volatile but volatile. From this perspective, as the standard for non-volatility, for example, the boiling point at normal pressure is higher than 193 °C, which is the boiling point of TEMPO, preferably 200 °C or higher, more preferably 220 °C or higher. Also, as the standard for non-volatility, for example, the vapor pressure at 20 °C is lower than 0.4 hPa, which is the vapor pressure of TEMPO at 20 °C (i.e., less than 0.4 hPa), and preferably lower than 0.2 hPa (i.e., less than 0.2 hPa). Each of the foregoing electrolytes 13 and 14 may also contain components other than the foregoing electrolyte solution and the foregoing redox compound. Examples of other components contained in each of the foregoing electrolytes 13 and 14 include polyethylene glycol, polyacrylate, polymethacrylate, and polyvinyl acetal. Each of the electrolytes 13 and 14 is in a layered form between the electrodes 11 and 12 and the separator 18 in the carbon dioxide adsorption battery 10. The thickness of each of the electrolytes 13 and 14 is not particularly limited, but for example, it is preferably 0.1 μm to 2 mm, more preferably 1 μm to 1 mm. If each of the electrolytes 13 is too thin, not only the amount of fixed carbon dioxide and the stored electricity amount decrease, but also there is a tendency to form minute holes in each of the electrolytes 13 and 14, that is, to form pinholes. If pinholes are formed, there are problems such as being unable to properly adsorb carbon dioxide and being unable to contribute to the current flow for carbon dioxide adsorption. Also, if each of the electrolytes 13 and 14 is too thick, the diffusion of carbon dioxide adsorbed on each of the electrolytes 13 and 14 within each of the electrolytes 13 and 14 becomes slow, resulting in a difference in the amount of fixed carbon dioxide and the stored electricity amount. Therefore, when charging, there is a tendency to become difficult to grasp that carbon dioxide is sufficiently adsorbed. The above is caused by the following. In the carbon dioxide adsorption battery 10, the help for the diffusion of carbon dioxide in each of the electrolytes 13 and 14 for the adsorption of carbon dioxide or the diffusion of the redox compound that binds carbon dioxide is greater than the help for the above diffusion during charging. Also, if each of the electrolytes 13 and 14 is thick, the influence of the above diffusion becomes greater compared to the case of being thin. From these viewpoints, the difference in the thickness of each of the electrolytes 13 and 14 when the adsorption rate of carbon dioxide is high and when it is low is greater than the difference in the thickness of each of the electrolytes 13 and 14 when the charging rate is high and when it is low. Therefore, when each of the electrolytes 13 and 14 is thin, it is relatively easy to grasp that carbon dioxide is sufficiently adsorbed from the stored electricity amount. When each of the electrolytes 13 and 14 is thick, as described above, a difference occurs in the amount of fixed carbon dioxide and the stored electricity amount, so it is difficult to grasp that carbon dioxide is sufficiently adsorbed from the stored electricity amount. Therefore, the thicker each of the electrolytes 13 and 14 is, the more difficult it becomes to grasp that carbon dioxide is sufficiently adsorbed when charging. Also, for the same reason, if each of the electrolytes 13 and 14 is too thick, there is a tendency to become difficult to grasp that carbon dioxide is sufficiently released when discharging. Each of the electrolytes 13 and 14 may contain a substrate. Examples of each of the electrolytes 13 and 14 include those in which the electrolyte solution containing the redox compound is impregnated into the substrate. Also, examples of the substrate include glass fiber filter paper and the like. The method for manufacturing the electrolyte 13 is not particularly limited as long as each of the electrolytes 13 and 14 can be manufactured. When each of the electrolytes 13 and 14 contains the substrate, examples include a method in which the redox compound is dispersed or dissolved in the electrolyte solution and the electrolyte solution containing the redox compound is impregnated into the substrate. The impregnation is preferably performed while applying ultrasonic vibration to either the electrolyte solution or the substrate. By doing so, the formation of minute holes in the electrolyte 13, that is, the formation of pinholes, can be suppressed. The first electrolyte 13 and the second electrolyte 14 are preferably arranged to be face-symmetrical with respect to the separator 18 (face-symmetrical with each other with the separator 18 as the center). By arranging as described above, the adsorption and desorption of carbon dioxide on the electrode side of any one of the pair of electrodes caused by reversing the voltage applied between the pair of electrodes 11 and 12 can be performed more reliably. Also, even when the voltage applied between the pair of electrodes 11 and 12 is reversed, the same performance can be maintained before and after the reversal. Therefore, the adsorption of carbon dioxide from a gas containing carbon dioxide can be performed more reliably as described above, while charging, and the carbon dioxide is desorbed during discharge. The ratio of the total amount of carbon dioxide that can theoretically react with the compound (a compound that can adsorb and desorb carbon dioxide through an electrochemical reaction) contained in the electrolyte solution on the first electrolyte 13 side relative to the separator 18 to the total amount of carbon dioxide that can theoretically react with the compound (a compound that can adsorb and desorb carbon dioxide through an electrochemical reaction) contained in the electrolyte solution on the second electrolyte 14 side relative to the separator 18 (total amount of carbon dioxide on the first electrolyte 13 side / total amount of carbon dioxide on the second electrolyte 14 side) is preferably 0.8 to 1.2, more preferably 0.9 to 1.1, and even more preferably 0.95 to 1.05. Also, it is particularly preferable that the total amount of the carbon dioxide on the first electrolyte 13 side relative to the separator 18 is the same as the total amount of the carbon dioxide on the second electrolyte 14 side relative to the separator 18. That is, it is particularly preferable that the ratio is 1. Here, the electrolyte solution compared with the above-mentioned separator 18 existing on the side of the first electrolyte 13 refers to the entire electrolyte solution compared with the above-mentioned separator 18 existing on the side of the first electrolyte 13 (or the first electrode 11). Specifically, for example, in the case of the carbon dioxide adsorption battery 10 shown in FIG. 1, it is the entire electrolyte solution existing on the left side compared with the above-mentioned separator 18. The total amount of carbon dioxide that can theoretically react with the above-mentioned compound contained in the electrolyte solution compared with the above-mentioned separator 18 existing on the side of the first electrolyte 13 can be obtained from the type and amount of the above-mentioned compound contained in the electrolyte solution compared with the above-mentioned separator 18 existing on the side of the first electrolyte 13. Also, the electrolyte solution compared with the above-mentioned separator 18 existing on the side of the second electrolyte 14 refers to the entire electrolyte solution compared with the above-mentioned separator 18 existing on the side of the second electrolyte 14 (or the second electrode 12). Specifically, for example, in the case of the carbon dioxide adsorption battery 10 shown in FIG. 1, it is the entire electrolyte solution existing on the right side compared with the above-mentioned separator 18. The total amount of carbon dioxide that can theoretically react with the above-mentioned compound contained in the electrolyte solution compared with the above-mentioned separator 18 existing on the side of the second electrolyte 14 can be obtained from the type and amount of the above-mentioned compound contained in the electrolyte solution compared with the above-mentioned separator 18 existing on the side of the second electrolyte 14. (Separator) The above-mentioned separator 18 is not particularly limited as long as it can inhibit the passage of the above-mentioned compound and can pass the electrolyte solution. That is, the above-mentioned separator 18 makes the above-mentioned compound more difficult to pass than the electrolyte solution. Also, as the above-mentioned separator 18, although it can pass the electrolyte solution, it is preferably one that does not allow the above-mentioned compound to pass. The above-mentioned separator 18 can pass the electrolyte solution, but is provided to separate the first electrolyte 13 and the second electrolyte 14 and inhibit the passage of the above-mentioned compound. Therefore, the pair of electrodes 11 and 12 are separated by the above-mentioned separator 18. As the above-mentioned separator 18, for example, a separator generally used in lithium secondary batteries can be cited. In particular, a separator with a low resistance to ion migration in the electrolyte and excellent moisture retention of the electrolyte solution is preferably used. As the material of the above-mentioned separator, for example, glass fiber, polyester, polyethylene, polypropylene, and polytetrafluoroethylene (PTFE) can be cited. As the material of the above-mentioned separator, it can be used alone or in combination of two or more. Also, the above-mentioned separator 18 is composed of the material of the above-mentioned separator 18. As its form, it can be a non-woven fabric or a woven fabric. The pore diameter of the above-mentioned separator 18 is not particularly limited, and is preferably, for example, 0.01 to 10 μm. Also, the thickness of the above-mentioned separator 18 is not particularly limited, and is preferably, for example, 5 to 300 μm. (Flow path) Each of the pair of flow paths 15 and 16 constituting the above-mentioned flow path is not particularly limited as long as it is a flow path through which gas can flow. Examples include a flow path through which at least one of carbon dioxide adsorbed on the above-mentioned compound and carbon dioxide desorbed from the above-mentioned compound can flow. Further, the first flow path 15 is connected to the first electrode 11 and can flow through the gas passing through the first electrode 11 and the gas released from the first electrode 11. Further, the second flow path 16 is connected to the second electrode 12 and can flow through the gas passing through the second electrode 12 and the gas released from the second electrode 12. Further, the pair of flow paths 15 and 16 may also be provided with valves 31, 32, 33, and 34 as needed. (Applying unit) As described above, the carbon dioxide adsorption battery 10 may also be provided with a voltage applying unit such as the applying unit 21 and the applying unit 23. By providing the applying units 21 and 23, the carbon dioxide adsorption battery 10 can be a carbon dioxide concentrating device. That is, a carbon dioxide concentrating device is obtained that includes the carbon dioxide adsorption battery 10 and the applying units 21 and 23 that apply a voltage between the pair of electrodes 11 and 12. The applying units 21 and 23 are not particularly limited as long as they can apply a voltage between the pair of electrodes 11 and 12. Examples of the applying units 21 and 23 include secondary batteries, external power sources, and capacitors. Further, the applying units 21 and 23 are preferably voltage applying units that can switch the levels of the potentials of the pair of electrodes 11 and 12. As described above, the carbon dioxide adsorption battery 10 can be a carbon dioxide concentrating device that can efficiently concentrate carbon dioxide by providing the applying units 21 and 23 that can switch the levels of the potentials of the pair of electrodes 11 and 12. That is, a carbon dioxide concentrating device is obtained that includes the carbon dioxide adsorption battery 10 and the applying units 21 and 23 that apply a voltage between the pair of electrodes 11 and 12, and the applying units 21 and 23 can switch the levels of the potentials of the pair of electrodes 11 and 12. After charging, as shown in FIGS. 2 and 4, when the carbon dioxide adsorption battery 10 is discharged, the resistor 22 is provided between the pair of electrodes 11 and 12 for discharging. The resistor 22 is not particularly limited as long as it can discharge the carbon dioxide adsorption battery 10. Regarding the aforementioned carbon dioxide adsorption battery 10, as long as it can be manufactured into the aforementioned structure, its manufacturing method is not particularly limited. Specifically, as the manufacturing method of the aforementioned carbon dioxide adsorption battery 10, examples include using the aforementioned first electrode 11, the aforementioned second electrode 12, the aforementioned first electrolyte 13, the aforementioned second electrolyte 14, the aforementioned first flow path 15, the aforementioned second flow path 16, and the aforementioned separator 18, and even using the aforementioned application parts 21 and 23 and the aforementioned resistor 22 as needed, in such a way as to form the structure shown in FIGS. 1 to 6, and assembling by a general assembly method, etc. [Other Carbon Dioxide Adsorption Batteries] The carbon dioxide adsorption battery 40 according to the second embodiment of the present invention, as shown in FIGS. 7 to 10, includes a pair of electrodes 41, 42 (a first electrode 41 and a second electrode 42), a separator 18 disposed between the pair of electrodes 41, 42, and a pair of flow paths 15, 16 (a first flow path 15 and a second flow path 16) respectively connected to the pair of electrodes 41, 42.

Then, the pair of electrodes 41, 42 includes an electrolyte containing a carbon dioxide-soluble electrolyte and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction. That is, the carbon dioxide adsorption battery 40 is the same as the carbon dioxide adsorption battery 10 except that the pair of electrodes 11, 12 includes the electrolyte.

Therefore, the aforementioned charge-discharge device can repeatedly charge and discharge each of the aforementioned carbon dioxide adsorption batteries alternately by including two or more of the aforementioned carbon dioxide adsorption batteries. From this perspective, this charge-discharge device becomes a charge-discharge device with high energy efficiency. Also, the aforementioned charge-discharge device can separate carbon dioxide. Furthermore, in the aforementioned first carbon dioxide adsorption battery 10a and the aforementioned second carbon dioxide adsorption battery 10b, when charging, carbon dioxide is adsorbed from a gas containing carbon dioxide (such as air containing nitrogen and carbon dioxide), and when discharging, the adsorbed carbon dioxide is released.

Therefore, the charge-discharge device 50 not only becomes a charge-discharge device with high energy efficiency, but also can efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the carbon dioxide during discharge. This specification discloses various aspects of the technology as described above, and the main technologies are summarized below. The carbon dioxide adsorption cell according to the first aspect of the present invention is a carbon dioxide adsorption cell that includes a pair of electrodes, a separator disposed between the pair of electrodes, electrolytes respectively disposed between the pair of electrodes and the separator, and a pair of flow paths respectively connected to the pair of electrodes. Each of the pair of electrodes is a gas-permeable electrode, and the electrolyte includes an electrolytic solution capable of dissolving carbon dioxide and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction. According to the above configuration, a carbon dioxide adsorption cell can be provided that can efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the carbon dioxide during discharge. The reason for this is as follows. Each of the pair of electrodes allows the gas present around each electrode to pass through. When the gas passes through each electrode, the gas passing through each electrode comes into contact with the electrolyte on the respective electrode side. From this perspective, when the gas present around each electrode contains carbon dioxide, the electrolyte on the side of the gas containing carbon dioxide comes into contact with carbon dioxide. Therefore, since the electrolyte contains an electrolytic solution capable of dissolving carbon dioxide, carbon dioxide dissolves in the electrolytic solution contained in the electrolyte on the side of the gas containing carbon dioxide. In the aforementioned carbon dioxide adsorption battery, if a voltage that electrochemically converts the aforementioned compound into a state capable of adsorbing carbon dioxide is applied between the pair of electrodes in the electrolyte on the side where the gas containing carbon dioxide exists, the carbon dioxide dissolved in the electrolyte is adsorbed onto the aforementioned compound. Also, due to the separator provided in the aforementioned carbon dioxide adsorption battery, the aforementioned compound is less likely to pass through than the electrolyte. Therefore, in the aforementioned carbon dioxide adsorption battery, the passage of the aforementioned compound is more inhibited than the passage of the electrolyte. That is, the aforementioned compound is less likely to pass through the separator than the electrolyte. From this perspective, the aforementioned compound that adsorbs carbon dioxide is not easily transferred to the electrolyte on the side where the gas containing carbon dioxide does not exist. Therefore, when the aforementioned compound adsorbs the carbon dioxide, the aforementioned carbon dioxide adsorption battery is in a charged state. Furthermore, since the carbon dioxide dissolved in the electrolyte is adsorbed onto the aforementioned compound, the dissolution of carbon dioxide in the electrolyte is promoted, and the aforementioned carbon dioxide adsorption battery appropriately proceeds to the charged state. From these perspectives, as shown in FIG. 1, in the aforementioned carbon dioxide adsorption battery, if a gas containing carbon dioxide flows through one of the pair of flow paths, and a voltage that electrochemically converts the aforementioned compound into a state capable of adsorbing carbon dioxide is applied between the pair of electrodes in the electrolyte on the side where the gas containing carbon dioxide flows, carbon dioxide can be adsorbed while charging. Also, as described above, in the aforementioned carbon dioxide adsorption battery, since the aforementioned compound is less likely to pass through the separator, even if the voltage application between the pair of electrodes is stopped, as long as the pair of electrodes are not electrically connected to discharge, the state where carbon dioxide is adsorbed onto the aforementioned compound, that is, the charged state, is appropriately maintained. After that, as shown in FIG. 2, if the pair of electrodes are electrically connected to discharge, the state where the aforementioned compound adsorbs carbon dioxide can be eliminated by an electrochemical reaction, and the carbon dioxide adsorbed onto the aforementioned compound desorbs from the aforementioned compound. Therefore, in the aforementioned carbon dioxide adsorption battery, during discharge, carbon dioxide is released from the electrode on the carbon dioxide adsorption side during charging. That is, in the aforementioned carbon dioxide adsorption battery, during discharge, carbon dioxide is released from the flow path (the flow path through which the gas containing carbon dioxide flows during charging) among the pair of flow paths that is connected to the electrode on the carbon dioxide adsorption side during charging. The gas released from the aforementioned carbon dioxide adsorption battery during discharge is the gas adsorbed onto the aforementioned compound in the aforementioned carbon dioxide adsorption battery during charging, that is, mainly carbon dioxide, and thus is a gas with a very high carbon dioxide concentration. From this perspective, the aforementioned carbon dioxide adsorption battery can concentrate carbon dioxide. Furthermore, as the discharge for electrically connecting between the pair of electrodes in the aforementioned carbon dioxide adsorption battery, the voltage applied between the pair of electrodes may also be reversed for the operation. By performing in this way, first, a discharge occurs between the pair of electrodes, and the gas adsorbed in the aforementioned compound in the carbon dioxide adsorption battery during charging, that is, carbon dioxide, is released. After that, as shown in FIG. 3, in the aforementioned state, by flowing a gas containing carbon dioxide through a flow path (the other flow path) different from the flow path through which the gas containing carbon dioxide flowed during charging in the pair of flow paths, in the above state, the electrolyte on the carbon dioxide adsorption side sandwiches the aforementioned separator, and the aforementioned compound contained in the electrolyte on the opposite side adsorbs carbon dioxide for charging. Then, as shown in FIG. 4, by performing a discharge, carbon dioxide can be released. From these viewpoints, in the aforementioned carbon dioxide adsorption battery, the adsorption and desorption of carbon dioxide can be performed from the electrode side of any one of the pair of electrodes. Also, by performing the adsorption and desorption of carbon dioxide from the electrode side of any one of the pair of electrodes, the deviation in the usage frequency of the electrodes is reduced, and thus the durability life of the electrodes can be extended. According to the foregoing, the aforementioned carbon dioxide adsorption battery can efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the aforementioned carbon dioxide during discharge. The carbon dioxide adsorption battery according to the second aspect of the present invention is a carbon dioxide adsorption battery including a pair of electrodes, a separator disposed between the pair of electrodes, and a pair of flow paths respectively connected to the pair of electrodes. Each of the pair of electrodes is an electrode through which gas can pass, and the pair of electrodes includes an electrolyte containing an electrolytic solution capable of dissolving carbon dioxide and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction. According to the configuration as described above, similar to the carbon dioxide adsorption battery according to the first aspect of the present invention, a carbon dioxide adsorption battery can be provided that can efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the aforementioned carbon dioxide during discharge. The foregoing is caused by the following reasons. Since the pair of electrodes includes the aforementioned electrolyte, the gas present around each electrode comes into contact with the aforementioned electrolyte contained in each electrode. From this viewpoint, when the gas present around each electrode contains carbon dioxide, the aforementioned electrolyte contained in the electrode on the side where the gas containing carbon dioxide is present comes into contact with carbon dioxide. Therefore, since the aforementioned electrolyte contains an electrolytic solution capable of dissolving carbon dioxide, carbon dioxide dissolves in the aforementioned electrolytic solution contained in the aforementioned electrolyte on the side where the gas containing carbon dioxide is present. The aforementioned carbon dioxide adsorption battery, similar to the carbon dioxide adsorption battery of the first aspect of the present invention, if a gas containing carbon dioxide flows through one of the pair of flow paths, a voltage that electrochemically converts the aforementioned compound into a state capable of adsorbing carbon dioxide is applied between the aforementioned pair of electrodes in the electrolyte on the side where the gas containing carbon dioxide flows, then carbon dioxide can be adsorbed and charged simultaneously. Furthermore, in the aforementioned carbon dioxide adsorption battery, since the aforementioned compound hardly passes through the aforementioned separator, even if the voltage applied between the aforementioned pair of electrodes is stopped, as long as the discharge is not performed by electrically connecting the aforementioned pair of electrodes, the state where carbon dioxide is adsorbed on the aforementioned compound can be appropriately maintained, and the charged state can be maintained. After that, if the aforementioned pair of electrodes are electrically connected to perform discharge, then similar to the carbon dioxide adsorption battery of the first aspect of the present invention, the carbon dioxide adsorbed on the aforementioned compound desorbs from the aforementioned compound. Therefore, in the aforementioned carbon dioxide adsorption battery, because during discharge, similar to the carbon dioxide adsorption battery of the first aspect of the present invention, carbon dioxide is released from the electrode on the side where the gas containing carbon dioxide exists during charging, the aforementioned carbon dioxide adsorption battery can concentrate carbon dioxide. Furthermore, in the aforementioned carbon dioxide adsorption battery, by reversing the voltage applied between the aforementioned pair of electrodes, similar to the carbon dioxide adsorption battery of the first aspect of the present invention, first, carbon dioxide is released. After that, in this state, by flowing a gas containing carbon dioxide through a flow path (the other flow path) different from the flow path through which the gas containing carbon dioxide flowed during charging in the aforementioned pair of flow paths, in the above state, the electrolyte on the carbon dioxide adsorption side sandwiches the aforementioned separator, and the aforementioned compound contained in the electrolyte on the opposite side adsorbs carbon dioxide to perform charging. From these viewpoints, in the aforementioned carbon dioxide adsorption battery, carbon dioxide adsorption and desorption can be performed from the electrode side of any one of the aforementioned pair of electrodes. Also, by performing carbon dioxide adsorption and desorption from the electrode side of any one of the aforementioned pair of electrodes, the deviation in the usage frequency of the electrodes is reduced, and thus the durability life of the electrodes can be extended. Based on the foregoing, the aforementioned carbon dioxide adsorption battery can efficiently adsorb carbon dioxide from a gas containing carbon dioxide, charge simultaneously, and desorb the aforementioned carbon dioxide during discharge. The carbon dioxide adsorption battery of the third aspect of the present invention is a carbon dioxide adsorption battery in which, in the carbon dioxide adsorption battery of the first or second aspect of the present invention, the aforementioned pair of electrodes are arranged in a face-symmetric manner with respect to the aforementioned separator. According to the above-described configuration, it is possible to more surely perform the adsorption and desorption of carbon dioxide from the electrode side of any one of the pair of electrodes by reversing the voltage applied between the pair of electrodes as described above. Further, even when the voltage applied between the pair of electrodes is reversed, the same performance can be maintained before and after the reversal. Therefore, it is possible to more surely perform the adsorption of carbon dioxide from a gas containing carbon dioxide as described above, while charging, and desorbing the carbon dioxide during discharging. The carbon dioxide adsorption battery according to the fourth aspect of the present invention is a carbon dioxide adsorption battery, in the carbon dioxide adsorption battery according to any one of the first to third aspects of the present invention, the flow path is a flow path through which at least one of carbon dioxide adsorbed on the compound and carbon dioxide desorbed from the compound can flow.

According to the above-described configuration, the carbon dioxide adsorption battery can more efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the carbon dioxide during discharging. This is due to the following reasons. In the carbon dioxide adsorption battery, in the electrolyte on the carbon dioxide adsorption side, the compound contained in the electrolyte layer undergoes electrolytic reduction to become a reduced body. Specifically, in the carbon dioxide adsorption battery, as a voltage for electrochemically converting the compound into a state capable of adsorbing carbon dioxide in the electrolyte on the side where the gas containing carbon dioxide flows, a voltage is applied such that the potential of one of the pair of electrodes becomes lower than the potential of the other electrode. Near the side of the electrode with the lower potential, the compound contained in the electrolyte layer undergoes electrolytic reduction to become a reduced body. Carbon dioxide dissolved in the electrolyte binds to the reduced body and is introduced into the electrolyte. From this viewpoint, carbon dioxide is introduced from the side of the one electrode. Thereafter, if discharging is performed, the compound that has become a reduced body undergoes electrolytic oxidation to return to the state before electrolytic reduction, and carbon dioxide is desorbed from the compound. From this viewpoint, carbon dioxide is released from the side of the one electrode. As described above, the compound can appropriately adsorb and desorb carbon dioxide with respect to the compound.

According to the above-described configuration, the carbon dioxide adsorption battery can more efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the carbon dioxide during discharging. This is due to the following reasons. In the aforementioned carbon dioxide adsorption battery, as a voltage for electrochemically converting the aforementioned compound into a state capable of adsorbing carbon dioxide in the aforementioned electrolyte on the side where the gas containing carbon dioxide flows, a voltage is applied such that the potential of one of the pair of electrodes becomes lower than the potential of the other electrode. If the potential of the electrode on the carbon dioxide adsorption side (one electrode) is lower than the potential of the other electrode (the other electrode), the electrolyte on the carbon dioxide adsorption side becomes a potential lower than the reduction potential of the aforementioned compound, and the aforementioned compound accepts electrons, adsorbs carbon dioxide, and is introduced into the aforementioned electrolyte. From this viewpoint, carbon dioxide is introduced from the side of the aforementioned one electrode. Thereafter, if discharging is performed, the potential of the aforementioned other electrode becomes the same as the potential of the aforementioned one electrode in the aforementioned one electrode. That is, the state where the potential is lower than the potential of the aforementioned other electrode disappears. Therefore, the state where the potential is lower than the reduction potential of the aforementioned compound also disappears. Therefore, electrons are supplied from the aforementioned compound to the outside, and carbon dioxide is desorbed from the aforementioned compound. From this viewpoint, carbon dioxide is discharged from the side of the aforementioned one electrode. As described above, the aforementioned compound can appropriately perform adsorption and desorption of carbon dioxide to the aforementioned compound.

If the potential of the electrode on the carbon dioxide adsorption side (one electrode) is lower than the potential of the other electrode (the other electrode), the potential of the electrolyte on the carbon dioxide adsorption side becomes lower than the potential at which the aforementioned redox compound is reduced. The aforementioned redox compound accepts electrons and becomes a reductant. Carbon dioxide dissolved in the aforementioned electrolyte binds to the reductant and is introduced into the aforementioned electrolyte. From this perspective, carbon dioxide is introduced from the side of the aforementioned one electrode. After that, if discharging is performed, the potential of the aforementioned other electrode becomes the same as the potential of the aforementioned one electrode in the aforementioned one electrode. That is, the state where the potential is lower than the potential of the aforementioned other electrode disappears. Therefore, the state where the potential is lower than the potential at which the aforementioned redox compound is reduced also disappears. Accordingly, electrons are supplied from the aforementioned redox compound that has become a reductant to the outside, and it returns to the state before electrolytic reduction, and carbon dioxide desorbs from the aforementioned redox compound. From this perspective, carbon dioxide is released from the side of the aforementioned one electrode. As described above, the aforementioned compound can appropriately adsorb and desorb carbon dioxide to the aforementioned compound. Therefore, the aforementioned carbon dioxide adsorption battery can more efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the aforementioned carbon dioxide during discharging.

According to the above configuration, the aforementioned carbon dioxide adsorption battery can more efficiently adsorb carbon dioxide from a gas containing carbon dioxide while charging, and desorb the aforementioned carbon dioxide during discharging. This is due to the following reasons. The aforementioned carbon dioxide adsorption battery, as described above, applies a voltage such that, in the aforementioned electrolyte on the gas side containing carbon dioxide, the aforementioned compound is made into a state capable of adsorbing carbon dioxide through an electrochemical reaction, and the potential of one of the aforementioned pair of electrodes becomes lower than the potential of the other electrode. If the potential of the carbon dioxide adsorption side electrode (one electrode) is lower than the potential of the other side electrode (the other electrode), the potential of the electrolyte on the carbon dioxide adsorption side becomes lower than the potential at which the aforementioned redox compound is reduced. The aforementioned N-oxy radical in the redox compound is reduced to form an N-oxy anion radical. Carbon dioxide dissolved in the aforementioned electrolyte binds to the N-oxy anion radical and is introduced into the aforementioned electrolyte. From this perspective, carbon dioxide is introduced from the aforementioned one electrode side. After that, if discharging is performed, the potential of the aforementioned other electrode becomes the same as the potential of the aforementioned one electrode in the aforementioned one electrode. That is, the state where the potential is lower than the potential of the aforementioned other electrode disappears. Therefore, the state where the potential is lower than the potential at which the aforementioned redox compound is reduced also disappears. Accordingly, the aforementioned N-oxy anion radical is oxidized to form an N-oxy radical or an N-oxy cation radical, and carbon dioxide desorbs from the aforementioned compound. From this perspective, carbon dioxide is released from the aforementioned one electrode side. As described above, the aforementioned compound can appropriately adsorb and desorb carbon dioxide to the aforementioned compound.

[Examples] [Example 1] <Fabrication of Carbon Dioxide Adsorption Battery> A carbon dioxide adsorption battery having the structure shown in FIGS. 1 to 4 was fabricated using the following steps. (Electrolyte: First Electrolyte and Second Electrolyte) To 100.0 g of dimethylformamide (manufactured by FUJIFILM Wako Pure Chemical Corporation), 6.5 g of Poly(vinylidenefluoride - co - hexafluoropropylene) (manufactured by Sigma - Aldrich) was added, and the mixture was stirred at 80°C for 3 hours for dissolution. Next, 24.0 g of a compound [poly(4 - methacryloyloxy - 2,2,6,6 - tetramethylpiperidinyloxy radical)] (non - volatile), which was obtained by polymerizing 4 - methacryloyloxy - 2,2,6,6 - tetramethylpiperidinyloxy radical (manufactured by Tokyo Chemical Industry Co., Ltd.), which belongs to the aforementioned redox compound as a monomer, was added to the obtained solution, and the mixture was stirred at 80°C for 3 hours for dissolution. Then, 12.9 g of an ionic liquid [1 - ethyl - 3 - methylimidazolium bis(fluorosulfonyl)imide (non - volatile) (emimFSI manufactured by Sigma - Aldrich)], which is an electrolyte capable of dissolving carbon dioxide, was added to the obtained solution, heated to 40°C, and stirred and mixed for 3 hours. Using the liquid obtained as described above, a liquid film with a thickness of 500 μm was fabricated on a glass plate with a spreader, and dried under reduced pressure at 60°C for 8 hours. The dried film obtained by the aforementioned drying was peeled off from the glass plate. By doing so, a dried film with a thickness of 100 μm was obtained. The obtained dried film was cut into a size of 20 mm in length × 24 mm in width and used as the electrolyte (electrolyte layer). After visually confirming the obtained electrolyte layer, no minute holes (pinholes) were confirmed. (Pair of Electrodes: First Electrode and Second Electrode) Multiple pieces of carbon paper (GDL35BC manufactured by SGL Carbon Japan Co., Ltd.) were cut into a size of 30 mm in length × 30 mm in width × 1 mm in thickness.

After that, perform constant current discharge at a discharge current (2.5 mA) until 0 V, and measure the discharge capacity (mAh / g) at this time. In addition, the discharge capacity is obtained in the form of the capacity per unit weight of each radical material in order to facilitate comparison of the efficiency of radical materials. When measuring the discharge rate characteristic evaluation, after the aforementioned charging is completed, use a portable carbon dioxide concentration meter (CGP-31 manufactured by Toa DKK Corporation) installed in the hole of the flow path on the first electrode side to measure the residual carbon dioxide concentration (CO concentration after charging). 2 Concentration). Also, after the aforementioned discharge, use a portable carbon dioxide concentration meter installed in the hole of the flow path on the first electrode side to measure the carbon dioxide concentration (CO concentration after discharge). 2 Concentration). (Second charge-discharge: Carbon dioxide adsorption and desorption test) Next, for the aforementioned carbon dioxide adsorption battery, during charging, as shown in Figure 3, connect the conductive copper foil tape of the first electrode and the conductive copper foil tape of the second electrode as the power source of the application part. Also, for the aforementioned carbon dioxide adsorption battery, during discharge, as shown in Figure 4, connect a resistor between the conductive copper foil tape of the first electrode and the conductive copper foil tape of the second electrode. Except for the above connections, perform charge-discharge under the same conditions as the first charge-discharge, and observe the behavior of carbon dioxide. The results are shown in Table 1. [Example 2] As the electrolyte (ionic liquid) capable of dissolving carbon dioxide, use 42.9 g of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide instead of 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide, and perform the same operations as in Example 1 to manufacture a carbon dioxide adsorption battery. Then, use the obtained carbon dioxide adsorption battery to perform the same evaluation as in Example 1. The results are shown in Table 1. [Example 3] As the first electrode and the second electrode, use the following electrodes to replace the cut carbon paper, and perform the same operations as in Example 1 to manufacture a carbon dioxide adsorption battery. Then, use the obtained carbon dioxide adsorption battery to perform the same evaluation as in Example 1. The results are shown in Table 1. Activated carbon (YP-50 manufactured by Kuraray Co., Ltd.), styrene-butadiene rubber (SBR) (TRD2001 manufactured by JSR Corporation), carboxymethyl cellulose (CMC) (CELLOGEN BSH manufactured by Daiichi Kogyo Seiyaku Co., Ltd.), and carbon black (Super-P manufactured by TIMCAL Graphite & Carbon) were made into activated carbon:SBR:CMC:carbon black = 90:3:2:5 (mass ratio) and mixed with water to obtain a slurry. Instead of carbon paper, a stainless-steel mesh (stainless-steel mesh, stainless-steel 304, mesh count 635 manufactured by Clever Co., Ltd.) was used. The obtained slurry was applied to the stainless-steel mesh with a bar coater and then dried in a glass tube oven at 150 °C for 7 hours under reduced pressure to obtain an activated-carbon-coated electrode (activated-carbon layer thickness 150 μm). This electrode was used as the aforementioned first electrode and the aforementioned second electrode. [Comparative Example 1] 28.4 g of a compound [poly(4-methacryloyloxy-2,2,6,6-tetramethylpiperidinyloxy radical)] (non-volatile), which was obtained by dissolving 4-methacryloyloxy-2,2,6,6-tetramethylpiperidinyloxy radical (manufactured by Tokyo Chemical Industry Co., Ltd.), which is a redox compound, as a monomer in 30.0 g of toluene and polymerizing it by the conventional anionic polymerization method, was dissolved. The solution obtained as described above was dropped onto the entire surface of a glass fiber filter paper (GC50 manufactured by ADVANTEC). After that, the glass fiber filter paper onto which the aforementioned solution was dropped was dried in a nitrogen atmosphere. By doing so, toluene was removed to obtain a solid electrolyte layer. An element was manufactured in the same manner as in Example 1, except that this solid electrolyte layer that does not contain an electrolyte capable of dissolving carbon dioxide was used. Then, using the obtained element, the same evaluation as in Example 1 was carried out. In addition, it was confirmed that no gas leaked from the flow path formed on the second electrode side. Also, this element did not adsorb carbon dioxide and did not store electricity, so it was simply referred to as an element. The results of these are shown in Table 1. [Comparative Example 2] A carbon dioxide adsorption battery was manufactured in the same manner as in Example 1, except that no redox compound was added. Then, using the obtained carbon dioxide adsorption battery, the same evaluation as in Example 1 was carried out. Furthermore, it was confirmed that no gas leaked from the flow path formed on the second electrode side. Also, this element did not adsorb carbon dioxide and did not store electricity, so it was simply referred to as an element. The results of these are shown in Table 1. [Comparative Example 3] A carbon dioxide adsorption battery was manufactured in the same manner as in Example 1, except that no flow path was provided on the second electrode side. Then, using the obtained carbon dioxide adsorption battery, the same evaluation as in Example 1 was carried out. The results are shown in Table 1. In addition, in Table 1, "-" in the column of discharge capacity indicates that power cannot be stored (the charged state cannot be maintained). [Table 1] As can be seen from Table 1: A carbon dioxide adsorption battery (Examples 1 to 3), in a battery having the aforementioned pair of electrodes, the aforementioned separator, the aforementioned electrolyte, and the aforementioned pair of flow paths, each of the aforementioned pair of electrodes is a gas-permeable electrode, the aforementioned electrolyte contains an electrolytic solution capable of dissolving carbon dioxide and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction, and it can be charged and discharged. Also, it can be seen that the carbon dioxide adsorption batteries of Examples 1 to 3, different from the case where they do not have this configuration (Comparative Examples 1 to 3), can adsorb and desorb carbon dioxide from either the first electrode or the second electrode. [Example 4] The same procedure as in Example 1 was carried out to manufacture the element. Then, using the obtained element, charging under the same conditions as the charging in the aforementioned first charge and discharge (the charging shown in Fig. 5) was carried out, and then, without discharging, charging under the same conditions as the charging in the aforementioned second charge and discharge (the charging shown in Fig. 6) was carried out. Charging was carried out under the conditions as described above, and moreover, the behavior of carbon dioxide was observed. [Comparative Example 4] A carbon dioxide adsorption battery was manufactured in the same manner as in Example 1, except that a flow path was not provided on the second electrode side in the aforementioned first charge. Then, using the obtained carbon dioxide adsorption battery, the same evaluation as in Example 4 was carried out. The results are shown in Table 2. [Table 2] As can be seen from Table 2: A carbon dioxide adsorption battery (Example 4), in a battery having the aforementioned pair of electrodes, the aforementioned separator, the aforementioned electrolyte, and the aforementioned pair of flow paths, each of the aforementioned pair of electrodes is a gas-permeable electrode, the aforementioned electrolyte contains an electrolytic solution capable of dissolving carbon dioxide and a compound capable of adsorbing and desorbing carbon dioxide through an electrochemical reaction, and by carrying out the charging shown in Fig. 5 and the charging shown in Fig. 6, even without discharging in between, carbon dioxide can be adsorbed and desorbed from either the first electrode or the second electrode.
