Abstract

Abstract This invention is directed to a single phase solid solvent-containing electrolyte having recurring units derived from a substituted allylic chloroformate incorporated within the solid polymeric matrix of the solid electrolyte. A novel electrolytic cell that incorporates the subject electrolyte also is provided. The specific molecular structure exhibited by such solid polymeric matrix is believed to advantageously facilitate the positioning of an inorganic ion salt and solvent between adjacent polymeric molecules during service within the solid electrolyte.
