Abstract
Abstract Electrochemical cells having an oxidizable active anode material; a cathode material selected from the group consisting of halogens and metal halides; and an electrolytic solution between and in contact with the anode and the cathode, the electrolytic solution comprising a liquid covalent inorganic oxyhalide or thiohalide solvent selected from the group consisting of monofluorophosphoryl dichloride, monobromophosphoryl difluoride, dibromophosphoryl monofluoride, monofluorothiophosphoryl dichloride, thiophosphoryl chloride, monobromothiophosphoryl difluoride, dibromothiophosphoryl monofluoride, and mixtures thereof, and a solute dissolved therein.
