Title: Cell having chalcogenide cathode and solvated alkali metal salt electrolyte. [preferred embodiment is Li/solvated metal--Li--halogen salt/TiS/sub 2/]

Abstract

A novel electrochemical cell has the following components: 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'A/sub p/, wherein M' is one or more metals selected from the group consisting of titanium, zirconium, hafnium, niobium, tantalum, and vanadium, A is one or more chalcogens selected from the group consisting of oxygen, sulfur, selenium, and tellurium, and p is a numerical value between about 1.8 and about 3.2; and a solid electrolyte consisting essentially of one or more solvated metal--alkali metal--halogen compounds of the formula ZMX/sub n/, wherein Z is an alkali metal, M is a metal selected from the group consisting of Zn, Cd, B, Al, Ga, In, Tl, Sn (stannous), P, and As, X is one or more halogens selected from the group consisting of chlorine, fluorine, bromine, and iodine, and n is a numerical value equal to one plus the valence of the metal M. Preferred are the cells wherein the anode is lithium, the cathode contains as its cathode-active material TiS/sub 2/, and the electrolyte consists essentially of a solid solvated metal--lithium--halogen salt.
