POLYMER GEL ELECTROLYTE COMPOSITION AND PROCESS FOR PRODUCING THE SAME

摘要

A polymer gel electrolyte composition which comprises: a three−dimensionally crosslinked polymer network matrix containing an electrolyte solution in a nonaqueous solvent; and an uncrosslinked polymer contained in the matrix. The uncrosslinked polymer comprises (a) ethylene units and/or propylene units and (b) units of an unsaturated carboxylic acid in which the carboxy group has been esterified with a polyalkylene glycol in which one of the terminal hydroxy groups has been protected.
