Electrochemical cell utilizing a mixture of phosphorus oxychloride and a low freezing solvent as the electrolyte

摘要

An electrochemical cell having an alkali metal anode; a cathode selected from the group consisting of halogens, metal halides, Group VI A elements and compounds thereof with metallic elements; and an electrolyte containing an inorganic solvent system and a solute dissolved in the solvent system. The solvent system comprises a mixture of phosphorus oxychloride, and a low freezing solvent selected from the group consisting of thionyl chloride, thiophosphoryl chloride, sulfuryl chloride and monofluorophosphoryl dichloride.
