Abstract
A polymer electrolyte-forming composition containing (A) a quaternary ammonium salt of general formula (1) below and (B) an ionic liquid can be converted into a polymer without compromising the excellent properties of the ionic liquid, thus enabling an electrolyte having an excellent safety and electrical conductivity and also a broad potential window to be obtained. In formula (1), Rto Rare each independently an alkyl group of 1 to 5 carbons or a substituent having a reactive unsaturated bond and any two from among Rto Rmay together form a ring, and Ris methyl, ethyl or a substituent having a reactive unsaturated bond, with the proviso that at least one of Rto Ris a substituent having a reactive unsaturated bond. X is a monovalent anion, the letter m is an integer from 1 to 8, and the letter n is an integer from 1 to 4.
