EXAMPLE - An electrolyte composition comprised 50 wt.% compound (F-31), 48 wt.% compound (F-32) and 2 wt.% dimethyl 2,2'-azo bis isobutylene (as heat polymerization initiator). The compound (F-31) was composed of an anion of formula (A-16) and a lithium cation. The compound (F-32) was composed of an anion of formula (A-16) and a cation of formula (C-2). The polymerization treatment was carried out at 80 degreesC for 1 hour.
