Abstract
The present invention is directed to a technique for enhancing an ionic conductivity of a polymer electrolyte composition composed of a matrix polymer containing at its backbone or side chain a Lewis base functional group; and a metal salt containing a metal ion and a counter ion; and optionally a plasticizer by mixing a promoter polymer therein. The promoter polymer contains a hydrogen-bond-forming functional group. The hydrogen-bond-forming functional group forms a hydrogen bond with said Lewis base functional group, creating an enhanced basicity of said Lewis base functional group and/or a reduced crystallinity of said matrix polymer, so that said ionic conductivity is improved.
