[0010] In the technical solution of the embodiment of the present application, when the electrode module is disposed in the electrolytic cell, the second conductive member is in communication with the first conductive member. When the electrode module is disassembled from the electrolytic cell, the second conductive member is automatically disconnected from the first conductive member. Moreover, the first conductive member is disposed on the electrolytic cell, and the working electrode, the counter electrode, and the reference electrode are all detachably disposed on the electrolytic cell. In this way, when it is necessary to replace the electrode, only the corresponding working electrode, counter electrode, or reference electrode needs to be disassembled from the electrolytic cell. At this time, the second conductive member on the working electrode, counter electrode, or reference electrode is automatically disconnected from the first conductive member. The entire process can be completed without disconnecting the first conductive member from the external circuit, thereby avoiding the step of reconnecting the first conductive member to the external circuit and effectively improving the replacement efficiency. Moreover, after the replaced working electrode, counter electrode, or reference electrode is installed on the electrolytic cell, the first conductive member is automatically in communication with the second conductive member without re-wiring, further improving the replacement efficiency.

[0071] Next, the present application will be described in detail.

[0072] In recent years, electrochemical technologies in fields including batteries, electrocatalysis, etc. have witnessed great development. Among them, as the most commonly used device that can most intuitively reflect the performance of different electrodes and electrolytes, the three - electrode electrolytic cell has received extensive attention in the research of its components and functions.

[0073] A general three - electrode electrolytic cell includes a working electrode, a reference electrode, and a counter electrode. Among them, when the working electrode, the reference electrode, or the counter electrode is in use, it is connected to an external circuit through a wire. When the electrode needs to be replaced, the wire on the electrode needs to be disconnected from the external circuit. After replacing the new electrode, the new electrode also needs to be re - connected to the external circuit. The entire process requires disconnecting the external circuit and then reconnecting the external cable, which is a complex process and has a low replacement efficiency.

[0074] To solve the problem of low replacement efficiency in the process of replacing electrodes in existing three - electrode electrolytic cells, an embodiment of the present application provides a three - electrode electrolytic cell device, as Figure 1 and in combination with Figure 2 shown, the three - electrode electrolytic cell device includes: an electrolytic cell 10, a conductive component, and an electrode module. Among them, the conductive component includes a first conductive member and a second conductive member. The first conductive member is disposed on the electrolytic cell 10. The electrode module includes a working electrode 13, a counter electrode 14, and a reference electrode 15. The working electrode 13, the counter electrode 14, and the reference electrode 15 are all detachably disposed inside the electrolytic cell 10; among the three electrodes of the working electrode 13, the counter electrode 14, and the reference electrode 15, at least one electrode is provided with a second conductive member; when the electrode module is disposed inside the electrolytic cell 10 or removed from the electrolytic cell 10, the second conductive member is connected or disconnected from the first conductive member.

[0075] In this embodiment, the shape of the electrolytic cell 10 is not specifically limited and can be common geometric structures such as square, circular, etc. Specifically, it can be determined according to the actual situation, and this specification embodiment does not limit this.

[0076] In this embodiment, the electrodes among the working electrode 13, the counter electrode 14, and the reference electrode 15 are electronic conductors or semiconductors that are in contact with the electrolyte solution or electrolyte, and are a multiphase system.

[0077] Among them, the working electrode 13 is also called the research electrode, which means that the reaction to be studied occurs on this electrode. In photoelectrochemistry, common working electrodes are photoelectrodes. The working electrode 13 can be solid or liquid, and all kinds of conductive solid materials can be used as electrodes. At the same time, the electrode material is determined in advance according to the research nature. The most common "inert" solid electrode materials are glassy carbon, platinum, gold, silver, lead, and conductive glass, etc. Due to experimental needs, the working electrode 13 is commonly fixed with a working electrode clamp, and commonly used ones are platinum electrode clamps and glassy carbon electrodes.

[0078] The counter electrode 14 is also called the auxiliary electrode. This electrode and the working electrode 13 form a circuit to make the current of the working electrode 13 smooth, so as to ensure that the reaction to be studied occurs on the working electrode. Compared with the working electrode 13, the counter electrode 14 should have a larger surface area, so that the externally applied polarization voltage acts on the working electrode 13. The resistance of the counter electrode 14 itself should be small and it is not easily polarized. During the experiment, the shape and position of the counter electrode 14 also have an impact on the experimental results. Commonly used counter electrodes 14 are platinum electrodes or graphite rod electrodes of different specifications and sizes.

[0079] The reference electrode 15 refers to an electrode with a known potential and close to an ideal non-polarizable electrode. There is basically no current passing through the reference electrode 15, which is used to measure the electrode potential of the working electrode 13 relative to the reference electrode 15. Different reference electrodes 15 can be selected for different research systems. Commonly used reference electrodes 15 include Ag / AgCl electrodes, saturated calomel electrodes, mercury-mercuric oxide electrodes, and mercurous sulfate electrodes, etc. Different reference electrodes need to be correctly selected according to the electrolyte solution system.

[0080] In this embodiment, both the first conductive member and the second conductive member can be wires, conductive sheets, etc., and can be specifically determined according to the actual situation, which is not limited in the embodiments of this specification.

[0081] The working principles of the working electrode 13, the counter electrode 14, and the reference electrode 15 in the electrolytic cell 10 in this embodiment are all prior arts and will not be elaborated here.

[0082] In the technical solution of the embodiment of the present application, when the electrode module is disposed in the electrolytic cell 10, the second conductive member is connected to the first conductive member. When the electrode module is disassembled from the electrolytic cell 10, the second conductive member is automatically disconnected from the first conductive member. Moreover, the first conductive member is disposed on the electrolytic cell 10, and the working electrode 13, the counter electrode 14, and the reference electrode 15 are all detachably disposed on the electrolytic cell 10. In this way, when it is necessary to replace the electrode, only the corresponding working electrode 13, counter electrode 14, or reference electrode 15 needs to be disassembled from the electrolytic cell 10. At this time, the second conductive member on the working electrode 13, counter electrode 14, or reference electrode 15 is automatically disconnected from the first conductive member. The whole process can be completed without disconnecting the first conductive member from the external circuit, thus avoiding the step of reconnecting the first conductive member to the external circuit and effectively improving the replacement efficiency. Moreover, after the replaced working electrode 13, counter electrode 14, or reference electrode 15 is installed on the electrolytic cell 10, the first conductive member is automatically connected to the second conductive member without re-wiring, further improving the replacement efficiency.

[0083] According to some embodiments of the present application, as Figure 1 shown, second conductive members are disposed on both the working electrode 13 and the counter electrode 14; or, as Figure 3 shown, second conductive members are disposed on both the working electrode 13 and the reference electrode 15; or, second conductive members are disposed on both the counter electrode 14 and the reference electrode 15; or, as Figure 5 shown, second conductive members are disposed on the working electrode 13, the counter electrode 14, and the reference electrode 15.

[0084] In this embodiment, a second conductive member is respectively provided on the working electrode 13 and the counter electrode 14, or a second conductive member is respectively provided on the working electrode 13 and the reference electrode 15, or a second conductive member is provided on both the counter electrode 14 and the reference electrode 15, or a second conductive member is respectively provided on the working electrode 13, the counter electrode 14, and the reference electrode 15. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0085] When it is necessary to replace the working electrode 13 and the counter electrode 14, or, when it is necessary to replace the working electrode 13 and the reference electrode 15, or, when it is necessary to replace the counter electrode 14 and the reference electrode 15, or, when it is necessary to replace the working electrode 13, the counter electrode 14, and the reference electrode 15, only the corresponding working electrode 13, counter electrode 14, and reference electrode 15 need to be disassembled from the electrolytic cell 10. At this time, the second conductive member on the working electrode 13, counter electrode 14, or reference electrode 15 is automatically disconnected from the first conductive member, and the entire process can be completed without disconnecting the first conductive member from the external circuit, thus avoiding the step of reconnecting the first conductive member to the external circuit and effectively improving the replacement efficiency.

[0086] According to some embodiments of the present application, such as Figure 1 and in combination with Figure 2 As shown, the first conductive member includes a first wire 18, and the second conductive member includes a second wire 16 and a first electrode rod 11. Wherein, one end of the first wire 18 is fixed in the inner wall 101 of the electrolytic cell 10, and the other end is located outside the electrolytic cell 10; the first electrode rod 11 is detachably arranged on the electrolytic cell 10, the second wire 16 is fixed to the first electrode rod 11, and the second wire 16 is electrically connected to the working electrode 13; when the first electrode rod 11 is arranged inside the electrolytic cell 10 or disassembled from the electrolytic cell 10, the second wire 16 is connected or disconnected from the first wire 18.

[0087] In this embodiment, a section of the first wire 18 located inside the electrolytic cell 10 can be integrally formed with the electrolytic cell 10, or, a wire hole (not marked in the figure) is provided on the inner wall 101 of the electrolytic cell 10, and a section of the first wire 18 located inside the electrolytic cell 10 is located in the corresponding wire hole. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0088] The first electrode rod 11 in this embodiment can be threadedly connected to the electrolytic cell 10, and one end of the first electrode rod 11 is located in the inner cavity of the electrolytic cell 10, or, the first electrode rod 11 is snap - connected to the electrolytic cell 10, and one end of the first electrode rod 11 is located in the inner cavity of the electrolytic cell 10. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0089] In this embodiment, the second wire 16 can be bonded to the first electrode rod 11 or wound around the first electrode rod 11, and specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0090] In this embodiment, since the first electrode rod 11 is detachably arranged on the electrolytic cell 10, by externally applying force to install or disassemble the first electrode rod 11, it is convenient to connect or disconnect the second wire 16 on the first electrode rod 11 from the first wire 18 fixed on the electrolytic cell 10.

[0091] According to some embodiments of the present application, the first electrode rod 11 includes a first guide rod 111 and a second guide rod 112 connected coaxially, wherein the diameter of the first guide rod 111 is larger than that of the second guide rod 112; as Figure 1 shown, the electrolytic cell 10 is provided with a first fixing hole 102 and a first through hole 103, wherein the diameter of the first fixing hole 102 is larger than that of the first through hole 103, one end of the first fixing hole 102 communicates with the outside, the other end communicates with the first through hole 103, and the first through hole 103 communicates with the inner cavity of the electrolytic cell 10; under the condition that the first electrode rod 11 is arranged on the electrolytic cell 10, the first guide rod 111 is located in the first fixing hole 102, and the second guide rod 112 passes through the first through hole 103 and is at least partially arranged inside the electrolytic cell 10.

[0092] The first guide rod 111 and the second guide rod 112 in this embodiment are integrally formed, or the first guide rod 111 is clamped on the second guide rod 112, and specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0093] Both the first fixing hole 102 and the first through hole 103 in this embodiment have a certain depth. For example, the depth of the first fixing hole 102 is 10 mm, 12 mm, etc., and the depth of the first through hole 103 is 6 mm, 8 mm, etc. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0094] Reference Figure 1As shown, since the electrolytic cell 10 is provided with a first fixing hole 102 and a first through hole 103, the diameter of the first fixing hole 102 is larger than that of the first through hole 103. One end of the first fixing hole 102 communicates with the outside, and the other end communicates with the first through hole 103. The first through hole 103 communicates with the inner cavity of the electrolytic cell 10. When the first electrode rod 11 is installed on the electrolytic cell 10, only the first electrode rod 11 needs to be inserted into the first fixing hole 102. At this time, the first guide rod 111 is located in the first fixing hole 102, and the second guide rod 112 extends into the electrolytic cell 10 after passing through the first through hole 103. In this way, the first electrode rod 11 can be fixed to the electrolytic cell 10 or removed from the electrolytic cell 10 by simple plugging and unplugging, effectively improving the installation efficiency of the first electrode rod 11.

[0095] According to some embodiments of the present application, as Figure 1 shown, a first protrusion 1111 is provided on the first guide rod 111, and a first groove 106 is provided in the inner wall 101 of the electrolytic cell 10, wherein the first protrusion 1111 cooperates with the first groove 106.

[0096] Referring to Figure 1 shown, in this embodiment, a first protrusion 1111 can be provided at the lower right of the first guide rod 111. Of course, it can be understood that the first protrusion 1111 can also be provided at the lower left of the first guide rod 111, etc., and can be specifically determined according to the actual situation, and the embodiments of this specification do not limit this.

[0097] In this embodiment, since a first protrusion 1111 is provided on the first guide rod 111, after the first guide rod 111 is inserted into the corresponding first fixing hole 102, the first protrusion 1111 is located in the first groove 106. In this way, the installation position of the first guide rod 111 on the electrolytic cell 10 can be effectively limited, thereby limiting the installation position of the first electrode rod 11, and further limiting the position and orientation of the working electrode 13 on the first electrode rod 11 inside the electrolytic cell 10.

[0098] According to some embodiments of the present application, as Figure 1 shown, the three - electrode electrolytic cell device further includes a first seal 26, which is disposed in the first through hole 103 and the first seal 26 is sleeved on the second guide rod 112.

[0099] In this embodiment, the first seal 26 is in the structure of a sealing ring. A groove is provided on the inner wall of the first through hole 103, and the first seal 26 is fixed in the corresponding groove. When the first electrode rod 11 passes through the first fixing hole 102 and the first through hole 103 from top to bottom and extends into the electrolytic cell 10, the sealing ring is sleeved on the second guide rod 112 on the first electrode rod 11 correspondingly. In this way, the sealing performance between the second guide rod 112 and the first through hole 103 is effectively improved, and the electrolyte in the electrolytic cell 10 is prevented from volatilizing to the outside through the first through hole 103.

[0100] According to some embodiments of the present application, as Figure 1 shown, the three-electrode electrolytic cell device further includes a first conductive sheet 17 and a second conductive sheet 19. Among them, the first conductive sheet 17 is arranged on the first guide rod 111, and the first conductive sheet 17 is connected to the second wire 16. The second conductive sheet 19 is arranged in the inner wall 101, and the second conductive sheet 19 is connected to one end of the first wire 18 located in the inner wall 101; under the condition that the first electrode rod 11 is arranged inside the electrolytic cell 10 or disassembled from the electrolytic cell 10, the first conductive sheet 17 and the second conductive sheet 19 are connected or disconnected.

[0101] In this embodiment, the first conductive sheet 17 can be fixed to the side of the first guide rod 111 by bolts, or the first conductive sheet 17 is clamped to the side of the first guide rod 111. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0102] Referring to Figure 1 shown, after the first conductive sheet 17 is fixed to the side of the first guide rod 111, the side of the first conductive sheet 17 facing away from the first guide rod 111 is flush with the side of the first guide rod 111.

[0103] In this embodiment, the second conductive sheet 19 can be fixed in the inner wall 101 by bolts, or the second conductive sheet 19 is clamped in the inner wall 101. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0104] Referring to Figure 1 shown, after the second conductive sheet 19 is fixed to the inner wall 101, the side of the second conductive sheet 19 facing the first conductive sheet 17 is flush with the circumferential side of the first fixing hole 102.

[0105] When the first guide rod 111 is installed in the first fixing hole 102, the first conductive sheet 17 and the second conductive sheet 19 are in contact and connected. When the first guide rod 111 is pulled out from the first fixing hole 102, the first conductive sheet 17 and the second conductive sheet 19 are automatically separated. By providing the first conductive sheet 17 and the second conductive sheet 19, the contact area when the second wire 16 and the first wire 18 are connected is increased, ensuring that the second wire 16 and the first wire 18 can be effectively connected.

[0106] According to some embodiments of the present application, as Figure 3 shown, under the condition that the first electrode rod 11 is disposed inside the electrolytic cell 10, the first conductive sheet 17 and the second conductive sheet 19 are plugged together.

[0107] In this embodiment, the plugging structure of the first conductive sheet 17 and the second conductive sheet 19 is equivalent to the mating structure of an existing plug and socket, which will not be elaborated herein.

[0108] Referring to Figure 3 shown, when the first conductive sheet 17 and the second conductive sheet 19 are distributed in the up-down direction, that is, the first conductive sheet 17 is located above the second conductive sheet 19, after the first conductive sheet 17 is fixed to the first guide rod 111, at least part or all of the first conductive sheet 17 is located below the first guide rod 111 on the first electrode rod 11.

[0109] After the second conductive sheet 19 is fixed to the inner wall 101, at least part or all of the second conductive sheet 19 is located in the corresponding first groove 106.

[0110] During installation, after the first guide rod 111 is installed into the first fixing hole 102, the first conductive sheet 17 on the first guide rod 111 extends into the corresponding first groove 106 and is snap-connected to the second conductive sheet 19, in this way, the stability of the first conductive sheet 17 and the second conductive sheet 19 during connection can be ensured.

[0111] According to some embodiments of the present application, a first contact is provided on the first conductive sheet 17, a second contact is provided on the second conductive sheet 19, and the first contact and the second contact cooperate.

[0112] Both the first contact and the second contact in this embodiment are metal contacts. When the first contact and the second contact are in contact under the condition of being powered on, the first conductive sheet 17 and the second conductive sheet 19 are in a connected state.

[0113] According to some embodiments of the present application, a gold plating layer (not marked in the figure) is provided on the first contact and / or the second contact.

[0114] In this embodiment, a gold plating layer can be provided on the first contact alone, or a gold plating layer can be provided on the second contact alone, or gold plating layers can be provided on both the first contact and the second contact. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0115] The gold plating layer in this embodiment can be selected as gold plating, copper plating, etc. Specifically, it can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0116] Since the gold plating layer can improve the uniformity and contact quality of the contact surface, reduce the generation of contact resistance, and the reduction of contact resistance can effectively reduce the energy loss during signal transmission, improve the transmission efficiency, and can reduce the wire heating, reduce signal attenuation and distortion, thereby ensuring the stability and accuracy of signal transmission.

[0118] In this embodiment, the first terminal 20 can be snap-fitted on the circumferential surface of the electrolytic cell 10, or the first terminal 20 can be fixed on the circumferential surface of the electrolytic cell 10 by bolts, and specifically can be determined according to the actual situation, and the embodiments of the present specification do not limit this.

[0119] In this embodiment, since the first terminal 20 is provided on the electrolytic cell 10, in this way, when it is necessary to connect an external circuit to the first wire 18, it is only necessary to fix the external circuit to the corresponding first terminal 20, thereby facilitating the connection of the external circuit.

In this way, a part of the second wire 16 can be fixed inside the first electrode rod 11. When the second guide rod 112 on the first electrode rod 11 extends into the electrolytic cell 10, it is possible to prevent the second wire 16 from contacting the electrolyte in the electrolytic cell 10 entirely.

[0124] According to some embodiments of the present application, the connection structure between the second electrode rod 12 and the electrolytic cell 10 is the same as the connection structure between the first electrode rod 11 and the electrolytic cell 10. Of course, it can be understood that the connection structure between the second electrode rod 12 and the electrolytic cell 10 may also be different from the connection structure between the first electrode rod 11 and the electrolytic cell 10, and specifically can be determined according to the actual situation, and the embodiments of this specification do not limit this.

[0128] According to some embodiments of the present application, the connection structure between the third wire 21 and the fourth wire 23 is the same as the connection structure between the second wire 16 and the first wire 18. Of course, it can be understood that the connection structure between the third wire 21 and the fourth wire 23 may also be different from the connection structure between the second wire 16 and the first wire 18, and specifically can be determined according to the actual situation, and the embodiments of this specification do not limit this.
