ABSTRACT OF THE DISCLOSURE A novel electrochemical cell is disclosed utilizing: (a) an anode which contains as the anode-active material an alkali metal; (b) a cathode which contains as the cathode-active material a chalcogenide of the empirical formula M'Zn 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 (c) an electrolyte consisting essentially of one or more solid alkali metal aluminum tetrahalide compounds of the formula MA1X4 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 TiS2, and the electrolyte consists essentially of LiA1C14.
