Rao, B M.L.; Sibernagel, B G

A novel electrochemical cell is disclosed utilizing an anode which contains as the anode-active material an alkali metal; a cathode which contains as the cathode-active material a chalcogenide of the empirical formula M'Z/sub n/, wherein M' is one or more metals selected from the group consisting of titanium, zirconium, hafnium, niobium, tantalum, and vanadium, Z is one or more chalcogens selected from the group consisting of oxygen, sulfur, selenium, and tellurium, and n is a numerical value between about 1.8 and about 3.2; and an electrolyte consisting essentially of one or more solid alkali metal aluminum tetrahalide compounds of the formula MA1X/sub 4/, wherein M is an alkali metal and X is one or more halogens selected from the group consisting of chlorine, bromine, and iodine. Preferred is the cell wherein the anode is lithium, the cathode contains as its cathode-active material TiS/sub 2/, and the electrolyte consists essentially of LiAlCl/sub 4/. 2 tables.
