Abstract
There is disclosed a polymer electrolyte composition that comprises a polymer having a structural unit represented by the following formula (1), at least one electrolyte salt selected from the group consisting of lithium salts, sodium salts, and magnesium salts, and a molten salt having a melting point of 250° C. or less: wherein X− represents a counter anion.
Claims13
A polymer electrolyte composition comprising:
- a polymer having a structural unit represented by the following formula (1):
- wherein X represents a counter anion;
- at least one electrolyte salt selected from the group consisting of lithium salts, sodium salts, magnesium salts, and calcium salts;
- and
- a molten salt having a melting point of 250° C. or less,
- wherein the molten salt is at least one selected from the group consisting of 1-ethyl-3-methylimidazolium-bis(trifluoromethanesulfonyl)imide, N,N-diethyl-N-methyl-N-(2-methoxyethyl)ammonium-bis(trifluoromethanesulfonyl)imide, and N-ethyl-N-methylpyrrolidinium-bis(trifluoromethanesulfonyl)imide, and
- wherein a content of the molten salt is 30% by mass or more and less than 55% by mass based on the total amount of the composition.
