Lithium ion-conductive polymer electrolyte and lithium ion battery

摘要

A lithium ion-conductive polymer electrolyte, comprising an acrylate, methacrylate, vinyl-ether or allyl-ether thermoplastic polymer containing a crown ether bonded to its side chain through a spacer, and a lithium salt as an electrolyte contained therein. The polymer electrolyte is solid at room temperature, can be formed into a film or the like and exhibits a good lithium ionic conductivity.
