Abstract: Disclosed is a process for making a solid electrolyte for use in solid state electrochemical device which process includes the use of a solvent comprising a low boiling point component having a boiling point not greater than about 100.degree. C. Specifically, the disclosed process comprises:(i) solvating a solid matrix-forming monomer or a partial polymer thereof in a solvent comprising at least one low boiling point solvent component having a boiling point not greater than 100.degree. C. and which is capable of solvating an electrolytic salt;(ii) coating the solvated monomer or partial polymer onto an electrode to form a layer of electrolyte precursor;(iii) covering said electrolyte precursor with a protective sheet layer which is substantially impervious to said solvent but which allows passage of radiation which cures the uncured electrolyte; and(iv) curing the electrolyte precursor by radiation through the sheet layer.

Abstract: This invention is directed to novel solid electrolytes containing a solid polymeric matrix having incorporated therein allylic ester or carbonate. The solid electrolytes are used in electrochemical cells.

Abstract: A method for making a cathode comprises introduction of polyethylene oxide into a suitable solvent prior to introduction of a compatible cathodic material and an electroconductive agent. The mixture of components forms a cathode paste which is used to form a cathode which can be employed in an electrolytic cell, e.g., a solid battery.

Abstract: A method and apparatus for drying a non-aqueous liquid electrolyte through the non-contact use of a desiccant includes a closed system having separate containers for the electrolyte and the desiccant. The closed system is charged with an inert gas, and a means is provided to circulate the gas between the containers. A stirring means is provided to stir the electrolyte to facilitate the release of water from the electrolyte.

Abstract: This invention is directed to solid electrochemical cells containing a solid radiation cured polymer electrolyte and a cathode composed of radiation cured polymer electrolyte and fullerene.

Abstract: This invention is directed to a novel acrylic alkoxy substituted silane and to a single phase solid solvent-containing electrolyte having recurring units derived from such silane 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.
