Claims
- 1. A totally inorganic rechargeable non-aqueous electrochemical cell comprising, a cathode, an anode of alkali or alkaline earth metal, and an electrolyte comprised of an electrolyte salt dissolved in sulfur dioxide, with said electrolyte being free of organic solvents; characterized in that said cathode is comprised of at least 60% by weight of a cathode active metal halide insoluble in said sulfur dioxide, said metal halide being admixed with a conductive carbon material and wherein said metal halide discharges in preference to said sulfur dioxide.
- 2. The cell of claim 1 wherein said metal halide is CuCl.sub.2 or CuBr.sub.2.
- 3. The cell of claim 1 wherein said anode is comprised of lithium.
- 4. The cell of claim 1 wherein said electrolyte salt is a gallium halide salt.
- 5. The cell of claim 1 wherein said electrolyte salt is an aluminum halide salt.
- 6. A totally inorganic rechargeable non-aqueous electrochemical cell comprising a lithium anode and an electrolyte consisting essentially of LiAlCl.sub.4 dissolved in SO.sub.2 characterized in that said cell contains a cathode comprised of at least 60% by weight of CuCl.sub.2 with said CuCl.sub.2 being admixed with a conductive carbon material and wherein said CuCl.sub.2 discharges in preference to said sulfur dioxide.
- 7. A totally inorganic rechargeable non-aqueous electrochemical cell comprising a lithium anode and an electrolyte consisting essentially of LiGaCl.sub.4 dissolved in SO.sub.2 characterized in that said cell contains a cathode comprised of at least 60% by weight of CuCl.sub.2 with said CuCl.sub.2 being admixed with a conductive carbon material and wherein said CuCl.sub.2 discharges in preference to said sulfur dioxide.
