Abstract
A polymer electrolyte composition including a metal salt and at least one polymer comprising a poly(glycidyl ether), where the at least one polymer is amorphous at ambient temperature. The poly(glycidyl ether) polymer can be a blend of poly(glycidyl ether) polymers, can be a poly(glycidyl ether) polymer blended with a mechanically strong solid polymer, and can be a block of a block copolymer that also includes a polymer block forming a mechanically strong solid polymer.
