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), R
1
to R
3
are each independently an alkyl group of 1 to 5 carbons or a substituent having a reactive unsaturated bond and any two from among R
1
to R
3
may together form a ring, and R
4
is methyl, ethyl or a substituent having a reactive unsaturated bond, with the proviso that at least one of R
1
to R
4
is 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.
