Novel polymer electrolyte for electrochemical power sources

摘要

A homogeneous single-phase polymer electrolyte containing a cyano monomer cross-linked with a second monomer having at least one α-unsaturated functionality, is described. A mixture of 2-cyanoethyl acrylate and a second monomer having α-unsaturated functionalities, such as multi-functional (meth)acrylates is preferred. The polymer electrolyte further includes a thermally activated initiator and a solvent system containing an ionizable salt. The preferred electrolyte is a polar aprotic organic compound having at least one ionizable lithium salt dissolved therein.
