Improved solid electrolyte obtained by the polymerization of diacrylate monomer having a rigid alkane segment

摘要

This invention is directed to single phase solid solvent-containing electrolyte having recurring units derived from a diacrylate monomer having relatively rigid alkane segments within the solid polymeric matrix of such solid electrolyte as described. A preferred diacrylate monomer is 1,6-hexanediol diacrylate. Also, in a preferred embodiment recurring oxyalkylene units of 2 to 3 carbon atoms which are relatively flexible in nature are absent in the polymer backbone of the resulting solid polymeric matrix. A novel electrolytic cell that incorporates the subject electrolyte also is provided. The specific molecular structure having recurring rigid alkane groups present therein as described is believed to include relatively stable three-dimensional openings between adjacent molecular chains which advantageously facilitate the positioning of an inorganic ion salt and solvent among adjacent polymeric molecules during service within the single phase solid electrolyte.
