Description

[Technical Field]

[0001] The present invention relates to a novel anion receptor compound and an electrolyte containing the same, and more particularly to a novel silazane-based anion receptor compound and an electrolyte containing the same. [Background technology]

[0002] Anion receptors improve anion stability through Lewis acid-salt interactions. These anion receptors are compounds containing electron-deficient atoms (N, B) that coordinate electron-rich anions around them, preventing the anion from binding to lithium cations as ion pairs and facilitating lithium cation migration. The first known anion receptors are azaethers composed of cyclic or linear amides substituted with perfluoroalkylsulfonyl groups, rendering the nitrogen atom of the amine group electron-deficient and enabling it to interact with electron-rich anions through Coulombic attraction (J. Electrochem. Soc., 143 (1996) 3825, 146 (2000) 9). However, these azaethers exhibit limited solubility in polar solvents typically employed in nonaqueous electrolytes, and their electrochemical stability window in the presence of LiCl salt does not meet the 4.0 V required for commercial anode materials. Furthermore, it was found that azaethers are unstable with LiPF6 (J. Electrochem. Solid-State Lett., 5 (2002) A248). That is, because LiPF6 is chemically and thermally unstable, even at room temperature, solid LiF and gaseous PF5 are in equilibrium, but the generation of this gaseous product, PF5, further shifts the equilibrium in favor of the production of PF5.

[0003] JPEG2025525467000002.jpg951

[0004] In non-aqueous solvents, PF5 tends to initiate a series of reactions, including ring-opening polymerization and the cleavage of ether bonds formed by atoms with lone electron pairs, such as oxygen or nitrogen. PF5, a strong Lewis acid, attacks electron pairs, but azaethers, due to their high electron density, are subject to immediate attack by PF5 (J. Power Sources, 104 (2002) 260). This severely limits the commercialization of azaether compounds. Given these limitations, McBreen et al. used the same method to synthesize an anion receptor using boron as the electron-deficient atom, substituted with an electron-attracting functional group (J. Electrochem. Soc., 145 (1998) 2813, 149 (2002) A1460).

[0005] Solid polymer electrolytes, on the other hand, are convenient to use due to their non-leakage electrolyte, high resistance to vibration and impact, and low self-discharge. They can also be used at high temperatures. These advantages are in line with the trend toward lighter and more compact portable electronic devices and wireless communication devices and home appliances. They are also widely applicable to high-capacity lithium polymer secondary batteries for electric vehicles and other applications. Therefore, much research has been conducted to improve their performance. Since P.V. Wright discovered polyalkylene oxide (PAO)-based solid polymer electrolytes in 1975 (British Polymer Journal, 7, 319), M. Armand coined the term "ion-conducting polymer" in 1978. A typical solid polymer electrolyte is composed of a polymer containing electron-donating atoms such as oxygen, nitrogen, or phosphorus, along with a lithium salt complex. The most representative solid polymer electrolyte known to date is polyethylene oxide (PEO) and its lithium salt complex, which exhibits a 100% ionic conductivity at room temperature. -8These PAO-based solid polymer electrolytes have low ionic conductivities (s / cm), making them unsuitable for electrochemical devices operating at room temperature. Because of their high crystallinity, these electrolytes restrict the movement of molecular chains, resulting in very low ionic conductivities at room temperature. To increase the mobility of molecular chains, the crystalline regions within the polymer structure must be minimized and the amorphous regions increased. To achieve this, research has been conducted using flexible siloxanes (Macromol. Chem. Rapid Commun., 7 (1986) 115) or phosphazenes (J. Am. Chem. Soc., 106 (1984) 6845) as the main chain, or introducing relatively short PAOs as side chains (Electrochem. Acta, 34 (1989) 635). Research is also underway to create network-structured solid polymer electrolytes by introducing one or more crosslinkable functional groups to the PAO terminals, but the ionic conductivities of these electrolytes at room temperature are only 10 or less. -5 ~10 -4 S / cm, which is unsuitable for use in lithium batteries operating at room temperature, and research is ongoing to improve this. To solve this problem, Abraham et al. introduced low-molecular-weight polyethylene oxide into vinylidene hexafluoride-hexafluoropropene copolymers to improve ionic conductivity (Chem. Mater., 9 (1997) 1978). In addition, by adding low-molecular-weight polyethylene glycol dimethyl ether (PEGDME) to a photocurable crosslinker with PEO side chains and siloxane main chain, it was possible to achieve a maximum ionic conductivity of 8 × 10 at room temperature under film-forming conditions. -4Ionic conductivities of up to 1000 S / cm have been demonstrated (J. Power Sources 119-121 (2003) 448). However, the calculated cycling efficiency on a Ni electrode was only about 53%. This low efficiency is explained by the rapid corrosion of the freshly deposited lithium surface, which results in passivation of the electrode surface (Solid State Ionics 119 (1999) 205, Solid State Ionics 135 (2000) 283). According to Vincent, the reaction between lithium salts and lithium metal proceeds as follows (Solid State Chem. 17 (1987) 145): the CF3 radicals generated here detach hydrogen atoms from the PEO polymer chains to form HCF3, and the resulting =COC- functional groups cleave the polymer backbone. At this time, the CH3 generated by the chain scission attacks the chain together with the CF3 radical or scisses the -CO- bond, resulting in Li-OR compounds adhering to the surface of the electrode and causing passivation.

[0006] JPEG2025525467000003.jpg1177

[0007] Therefore, to solve the above problems, it is necessary to design a compound with a structure that does not have a nitrogen atom that is easily attacked in the middle of the bond, such as an azaether, or to research a new material that can eliminate electrochemical instability and instability to lithium salts and increase ionic conductivity by replacing PAO-based plasticizers.

[0352] The present invention relates to electrolyte compositions containing the novel anion receptors according to the present invention.

[0354] According to one embodiment of the present invention, the electrolyte composition further includes the novel silazane compound; and at least one compound selected from the linear hydrocarbon compound represented by Chemical Formula 6, the cyclic hydrocarbon compounds represented by Chemical Formulas 7 to 11, the polyalkylene oxide compound represented by Chemical Formula 12, and the siloxane compounds represented by Chemical Formulas 13 to 15, each of which has a nitrogen atom in an amine group substituted with an electron-withdrawing group introduced therein.

[0355] Among the functional groups introduced as side chains, amine groups or nitrogen atoms in the ring substituted with electron-withdrawing groups can enhance the dissociation of alkali metal salts, thereby increasing electronegativity and cation mobility. For example, electron-withdrawing groups such as -SO2CF3, -OSO2CF3, -SO2CHF2, -OSO2CHF2, -SO2CH2F, -OSO2CH2F, -COCF3, -OCOCF3, -COCHF2, -OCOCHF2, -COCH2F, -OCOCH2F, -SO2CN, -OSO2CN, -SO2F, -OSO2F, -CF3, and -OCF3 make the amine group or nitrogen in the ring electron-deficient, forming electrically neutral complexes with the anionic species of the alkali metal salt and enhancing the dissociation of the alkali metal salt. Furthermore, because the hydrogen atoms of the amine groups are substituted with electron-withdrawing groups and the nitrogen atoms are located only at the ends of the hydrocarbon chains, the electrochemical instability, instability to lithium salts (e.g., LiPF6), and steric hindrance caused by the presence of a vulnerable nitrogen atom in the middle of the bond, as in the azaethers introduced in U.S. Pat. Nos. 5,705,689 and 6,120,941, can be eliminated. Furthermore, the nitrogen center is more exposed, allowing easy access for large anions, which promotes dissociation of the lithium salt and increases cation mobility, resulting in high ionic conductivity.

Preferably, the total content of the polymer compound, the crosslinkable polymer compound, and the anion receptor in the electrolyte composition for the solidified electrolyte is 12 wt % or more, or 13 wt % or more. When included in an amount equal to or greater than this minimum content range, the electrolyte or battery can be solidified to provide a rapid curing reaction at temperatures above a fire risk, such as about 130°C or higher. Furthermore, the nonaqueous solvent (d) can be present in an amount of 20 wt % to 80 wt % of the electrolyte composition for the solidified electrolyte.

[0500] According to one embodiment of the present invention, the solidified electrolyte may be prepared from the electrolyte composition for the gel polymer electrolyte and / or the electrolyte composition for the solid polymer electrolyte, or may be an electrolyte composition in which a curing reaction has not progressed. Furthermore, the solidified electrolyte has a viscosity and / or fluidity similar to or similar to that of a liquid. When applied to a battery, the solidified electrolyte rapidly cures at a certain temperature, for example, at a high temperature of 120°C or higher, or at a high temperature of 130°C or higher, thereby interrupting the operation of the battery and preventing thermal runaway and fire risks by ensuring battery stability at high temperatures.

[0501] According to one embodiment of the present invention, the polymer electrolyte thin film may be prepared by, for example, a curing process using an electrolyte composition for the gel polymer electrolyte and / or an electrolyte composition for the solid polymer electrolyte.

[0503] In one example of the present invention, when the gel polymer electrolyte thin film is formed,

[0504] The step of preparing the electrolyte composition may involve preparing a gel polymer electrolyte composition, placing a non-aqueous solvent, an anion receptor, an alkali metal ion-containing material, etc. in a container in an appropriate mixing ratio, stirring the mixture with a stirrer to prepare a solution, and then adding and mixing the polymer support. During mixing, the polymer support may be melted by applying a predetermined amount of heat as needed to prepare a gel polymer electrolyte composition mixture for preparing the gel polymer electrolyte thin film of the present invention.

[0505] For example, the thin film forming step can be performed by coating the prepared composition mixture to an appropriate thickness on a support substrate made of glass or polyethylene, or a commercially available Mylar film, and then drying the coated substrate, or exposing it to electron beams, ultraviolet rays, or gamma rays, or heating it to cause a curing reaction to form a thin film. As another example, the thin film forming step can be performed by applying the composition mixture to the support substrate, fixing spacers for adjusting the thickness on both ends of the support substrate, covering it with another support substrate, and then causing a curing reaction using the curing irradiator or heat source to form a gel-type polymer electrolyte thin film.

[0506] In one example of the present invention, when forming the solid polymer electrolyte thin film,

[0507] For example, the step of preparing the electrolyte composition may involve preparing a solid polymer electrolyte composition. The anion receptor, polyalkylene glycol dialkyl ether, or non-aqueous solvent and alkali metal ion-containing material may be placed in a container in an appropriate mixing ratio, the mixture may be stirred with a stirrer to prepare a solution, and then a network, branched, or comb-like polymer compound or a crosslinkable polymer compound may be added and mixed. The network, branched, or comb-like polymer compound may then be dissolved by applying a predetermined amount of heat, if necessary, during mixing. In the case of a crosslinkable polymer compound, a curing initiator and a polymerization inhibitor may be added to the mixture and stirred to prepare a solid polymer electrolyte composition mixture for preparing a solid polymer electrolyte thin film of the present invention.

[0508] For example, the thin film forming step can be performed by coating the prepared composition mixture to an appropriate thickness on a support substrate made of glass or polyethylene, or a commercially available Mylar film, and then drying the coated substrate, or exposing it to electron beams, ultraviolet rays, or gamma rays, or heating it to cause a curing reaction. As another example, the thin film forming step can be performed by applying the composition mixture to the support substrate, fixing spacers for adjusting the thickness on both ends of the support substrate, covering it with another support substrate, and then causing a curing reaction using the curing irradiator or heat source to produce a solid polymer electrolyte thin film.

For example, in the case of a waste battery used for an electric vehicle, there is a high risk of explosion and fire when it is charged, so a process of completely discharging the charged current and then separating the battery pack into individual cells may be necessary. Each discharged cell can be evaluated for its charge capacity and discharge capacity using a charger / discharger, and classified according to its capacity.

[0546] For example, cells are divided into those with capacities over 80%, 68% to 80%, and below 68%, and the regeneration process is performed on cells with a significant drop in capacity below 68%. Cells with a drop in capacity are fully discharged, and then holes are drilled in each cell in a dry room or inert atmosphere, and the existing electrolyte, generated gas, and impurities are removed under vacuum. An electrolyte containing an additive that can restore performance is then injected into the cell to seal the holes, and the cell is then rocked for a certain period of time under a constant temperature (25°C to 50°C) to evenly distribute the electrolyte, activate the anode and cathode active materials, and increase the activity of Li-ions, restoring the battery's capacity.

[0812] A solid polymer thin film was produced in the same manner as in Example 6, using the composition of the compounds used as shown in Table 1. As shown in Table 1, the polymer electrolyte of the comparative example did not contain an anion receptor.

[0813]

[0814] Experimental Examples 1-28. Ion Conductivity Experiments

[0815] The ionic conductivity was measured for the solid polymer electrolyte thin films produced in Examples 6 to 32 and Comparative Example 1. The ionic conductivity was measured by the following method.

[0816] The solid polymer electrolyte composition was applied to a band-type conductive glass substrate or a lithium-copper foil, photo-cured, and thoroughly dried. The AC impedance between the band-type or sandwich-type electrodes was measured under a nitrogen atmosphere, and the measured value was analyzed using a frequency response analyzer to obtain the complex impedance.

[0817] The band-type electrodes were fabricated by attaching 0.5-2 mm wide masking tape to the center of conductive glass (ITO) at intervals of about 0.5-2 mm, etching it in an etching solution, and then washing and drying. The ionic conductivity of the fabricated solid polymer electrolyte thin film was measured at a temperature of 30°C, and the results are shown in Table 2 below.

[0818]

[0819] [Table 2] JPEG2025525467000239.jpg7548

[0820] The above results show that the solid polymer electrolyte containing an anion receptor exhibits higher ionic conductivity than the solid polymer electrolyte not containing an anion receptor.

[0821]

[0822] Example 33. Fabrication of a battery using a liquid electrolyte containing an anion receptor

[0823] Anion receptor compound 1-1 (AR-8B, 0.015 g) prepared in Example 1-1 and anion receptor compound 3-1 (AR-7, 0.015 g) prepared in Example 3-1 were mixed with organic solvent EC / DMC / EMC (1:1:1, 1M LiPF6) (1.0 g). A battery was assembled in a dry room (humidity: 3% or less) by sandwiching a polypropylene separator impregnated with the above mixture solution between an NMC ternary anode and a graphite carbon cathode, and vacuum sealing the mixture.

[0824]

[0825] Comparative Example 2. Preparation of a battery using a liquid electrolyte containing no anion receptor

[0826] A separator impregnated with 1.0 g of organic solvent EC / DMC / DEC (1:1:1, 1M LiPF6), an NMC ternary anode, and a graphite carbon cathode were assembled in the same manner as in Example 33 to prepare a battery.

[0827]

[0828] Experimental Example 29. Lithium cycling performance experiment

[0829] The lithium cycling performance and efficiency of the batteries prepared in Example 33 and Comparative Example 2 were measured at room temperature using a charge-discharge tester (Maccor 4000). Charge and discharge were performed at 1 C. The batteries were charged and discharged at 0.6 mA / cm against an NMC counter electrode. 2 (Charging), 1.5mA / cm 2 The battery was charged and discharged between 3.0 V and 4.2 V at a constant current density (discharge).

[0830] A comparison of the capacity retention rate at high temperature (60°C) over time between batteries manufactured using an electrolyte containing anion receptor compound 1-1 of the present invention and an electrolyte not containing anion receptor compound 1-1 of the present invention is shown in Figure 1. The batteries using electrolytes containing anion receptor compound 1-1 (AR-7 in Figure 1) and anion receptor compound 3-1 (AR-8B in Figure 1) showed significantly higher capacity retention rates than the batteries using an electrolyte not containing anion receptor compound (Ref).

[0831] Therefore, the above results suggest that the use of an anion receptor results in a high capacity retention rate and a low internal resistance increase rate at high temperatures, which indicates an extension of the battery's lifespan and high-temperature stability.

[0832] The present invention also provides a reusable battery in which the waste electrolyte in a used electric vehicle battery (waste battery) is replaced and filled with the electrolyte to which the anion receptor has been added.

[0833] The following describes how to make a reusable battery by replacing and filling the novel electrolyte containing the anion receptor of the present invention.

[0834] The method for manufacturing a reusable battery of the present invention includes the steps of preparing a waste battery, removing waste electrolyte and other impurities from the waste battery, and regenerating the waste battery by injecting the novel electrolyte of the present invention into the waste battery.

[0835] The step of removing the waste electrolyte and other impurities from the waste batteries may be carried out in a dry room or in an inert atmosphere.

[0836] Alternatively, the step of removing the waste electrolyte and other impurities from the waste batteries may be performed under vacuum conditions.

[0837] The step of injecting a new electrolyte into the waste battery to regenerate it may be performed by applying vibration at a constant temperature after injecting the new electrolyte into the waste battery, and the constant temperature may be 20 to 50°C.

[0838] To explain the method of recycling the waste batteries in more detail, in the case of used electric vehicle batteries, there is a high risk of explosion and fire when they are charged, so it is necessary to completely discharge the charged current and then separate the battery pack into individual cells. Each discharged cell is evaluated for its charge capacity and discharge capacity using a charger / discharger, and classified according to its capacity.

[0839] For example, the cells are divided into those with capacities of 80% or more, 68% to 80%, and 68% or less, and the cells with a significantly reduced capacity of 68% or less are subjected to a regeneration process.

[0840] Cells with reduced capacity should be fully discharged and then stored in a dry room or inert atmosphere. A hole is drilled in each cell and a vacuum is used to remove the existing electrolyte, generated gas, and impurities. An electrolyte containing an additive that can restore performance is then injected into the cell and the hole is sealed. The cell is then shaken for a certain period of time at a constant temperature (25-50°C) to distribute the electrolyte evenly, activating the anode and cathode active materials and increasing the activity of the Li-ions, thereby restoring the battery's capacity.

[0841] The method of using the electrolyte of the present invention to make a reusable battery is described in detail below.

[0842]

[0843] Example 34. Fabrication of a reusable battery

[0844] (1) Preparation of waste batteries

[0845] In this example, modules were disassembled from battery packs used in electric buses and separated into unit cells. Cells classified based on discharge capacity as less than 12 Ah (less than 68% of the initial capacity) were then discharged to 2.5 V at 0.5 C. Then, in an inert atmosphere in a dry room or glove box, holes were pierced in the cells using a syringe and vacuum suction was applied to remove the existing waste electrolyte, generated gas, and impurities before use.

[0846]

[0847] (2) Cell reassembly and activation

[0848] The novel electrolyte of the present invention was injected using a syringe, the hole was sealed, and then the battery was aged by shaking it from side to side while maintaining the temperature at 25 to 30°C. After that, a current of 0.1C rate (2.1A) was applied to charge the battery to 4.2V at a constant current, and then a constant voltage charge of 4.2V was performed at a current value of 0.01C (0.21A).

[0849]

[0850] Comparative Example 3. Manufacturing of a reusable battery

[0851] The battery was prepared in the same manner as in Example 34, except that a non-aqueous electrolyte containing 1M LiPF6 in a mixed solvent of EC:EMC:DMC in a volume ratio of 3:3:4 was used without any additives.

[0852]

[0853] Experimental Example 30. Evaluation of reusable batteries

[0854] The battery produced in Example 34 was evaluated for constant current discharge capacity at a current value of 0.1 C (2.1 A) in the range of 3.0 to 4.2 V using a charger / discharger. As a result, the discharge capacity recovered from 6.2 Ah to 14.8 Ah.

[0855] On the other hand, evaluation of the battery produced in Comparative Example 3 showed that although the discharge capacity increased from 6.2 Ah to 10.5 Ah, a sufficient capacity was not recovered.

[0856]

[0857] The present invention also provides a solidified electrolyte that uses the electrolyte of the present invention to operate as a normal lithium ion battery until it reaches a certain temperature (preferably 70°C), and then rapidly hardens (within 5 to 10 minutes) to stop the operation of the battery when it reaches a certain temperature (preferably 130°C) or higher, in order to prevent the risk of fire caused by a sudden rise in battery temperature due to thermal runaway.

[0858] The method for producing the solid electrolyte containing the anion receptor of the present invention will be described below.

[0859] In the case of a solidified electrolyte, first, an anion receptor, a crosslinking agent, a curing initiator, and a polymerization inhibitor are added to an electrolytic solution, and the mixture is stirred to prepare a composition mixture for producing the solidified electrolyte of the present invention, as shown in Table 3 below.

[0860] A manufacturing example of the solidified electrolyte composition mixed solution and the results of the hardening experiment will be described in detail below.

[0861]

[0867]

[0868] Comparative Example 6. Production of solid electrolyte

[0869] 6.04 g of a crosslinking agent (TEGDA), anion receptor compound 1-1, an electrolyte solution, and an initiator were mixed in the same amounts as those in Comparative Example 3 to prepare a solid electrolyte.

[0871] Comparative Example 7. Production of solid electrolyte

[0872] 6.00 g of a crosslinking agent (TEGDA), anion receptor compound 1-1, an electrolyte solution, and an initiator were mixed in the same amounts as those in Comparative Example 3 to prepare a solid electrolyte.

[0873]

[0874] Comparative Example 8. Production of solid electrolyte

[0875] 5.40 g of a crosslinking agent (TEGDA), anion receptor compound 1-1, an electrolyte, and an initiator were mixed in the same amounts as those in Comparative Example 3 to prepare a solid electrolyte.

[0876]

[0877] Comparative Example 9. Production of solid electrolyte

[0878] 4.50 g of a crosslinking agent (TEGDA), anion receptor compound 1-1, an electrolyte, and an initiator were mixed in the same amounts as those in Comparative Example 3 to prepare a solid electrolyte.

[0879]

[0880] Comparative Example 10. Production of solid electrolyte

[0881] Anion receptor compound 1-1 (0.30 g) prepared in Example 1 and 8.40 g of triethylene glycol dimethacrylate (manufactured by Aldrich, "TEGDA") as a crosslinker were mixed with 60 g of electrolyte (EC:EMC:DMC=3:3:4, LiPF 61 mol / L). To this mixture, 0.01 g of Luperox TBEC (manufactured by Aldrich) as an initiator and 1.2 mg of 4-methoxyphenol as a polymerization inhibitor were added to prepare a solid electrolyte.

[0882]

[0883] Example 35. Preparation of solid electrolyte

[0884] Anion receptor compound 1-1 (0.33 g) prepared in Example 1 and 9.23 g of triethylene glycol dimethacrylate (manufactured by Aldrich, "TEGDA") as a crosslinker were mixed with 60 g of electrolyte (EC:EMC:DMC=3:3:4, LiPF 61 mol / L). To this mixture, 0.01 g of Luperox TBEC (manufactured by Aldrich) as an initiator and 1.2 mg of 4-methoxyphenol (manufactured by Aldrich) as a polymerization inhibitor were added to prepare a solid electrolyte.

[0887]

[0888] Experimental Example 31. Hardening experiment of solidified electrolyte (1)

[0889] The solidified electrolyte solutions prepared in Comparative Examples 4 to 9 were placed in 50 ml round flasks, and the curing times were measured by visual observation at 50°C, 70°C, 90°C, 110°C, and 130°C under a nitrogen atmosphere.

[0890] The measurement results of Comparative Examples 4 to 9 are shown in Table 4 below.

[0891] [Table 4] JPEG2025525467000241.jpg2366

[0892]

[0893] (In the table above, X means uncured and O means cured)

[0894] From Table 4, it can be seen that in the cases of Comparative Examples 4 to 6, all of them hardened at temperatures between 50°C and 130°C and could not be used as a solidifying agent. In addition, in the cases of Comparative Examples 7 to 9, none of them hardened at temperatures between 50°C and 130°C and could not be used as a solidifying agent either.

[0895] From Table 4 above, it can be seen that in order to achieve cure, the total content of additives must be at least 12.33%.

[0896]

[0897] Experimental Example 32. Hardening experiment of solidified electrolyte (2)

[0898] The solidified electrolyte solutions prepared in Comparative Example 10 and Example 35 were measured for their hardening times in the same manner as in Experimental Example 31.

[0899] The measurement results of Comparative Example 10 and Example 35 are shown in Table 5 below.

[0900] [Table 5] JPEG2025525467000242.jpg1177

[0901] (In the table above, X means uncured and O means cured)

[0902] From Table 5, it can be seen that in the case of Example 35, it does not harden at temperatures below 70°C, but hardens rapidly in just 5 minutes at a high temperature of 130°C, making it usable as a solidifying agent. However, in the case of Comparative Example 10, it hardens even at temperatures below 70°C, making it unusable as a solidifying agent.

[0903] From Table 3, it can be seen that in both Example 35 and Comparative Example 10, when 1.2 mg of polymerization inhibitor was added, the total content of additives was at least 13.74% as in Example 35, and the composition could be used as a solidifier without hardening at temperatures below 70°C.

[0904] As described above, liquid electrolytes using the novel anion receptor additives according to the present invention can provide electrolytes with improved lithium cycling performance and efficiency, and thus can be used as electrolyte additives for high-capacity lithium-ion batteries. Furthermore, polymer electrolytes containing the novel anion receptors of the present invention can provide electrolytes with significantly improved ionic conductivity and electrochemical stability at room temperature, and thus can be widely used as polymer electrolytes for compact lithium polymer secondary batteries used in various electronic devices, such as mobile phones, laptops, and camcorders, as well as for large-capacity lithium polymer secondary batteries used in power storage devices for power leveling and electric vehicles. Furthermore, a solid electrolyte is provided that rapidly hardens within five minutes above a certain temperature (130°C), thereby reducing the battery's performance and preventing the risk of fire caused by a sudden rise in temperature due to thermal runaway. Demand for such solid electrolytes is expected to grow not only in electric vehicle batteries, where ensuring safety during use is a top priority due to the recent frequent occurrence of fire accidents, but also in power storage devices.
