Title: Chalcogenide electrochemical cell

Abstract

A battery is provided in which the anode contains an alkali metal in a high state of thermodynamic activity; the cathode comprises a partially alkali metal-intercalated chalcogenide of the formula AYMYZX wherein a is an alkali metal more electropositive and larger than the anode alkali metal, M is a transition metal of group IV or V, X is a numerical value of from about 1.8 to about 2.1, Y is a numerical value of from about 0.01 to about 1 and Z is sulfur, selenium or tellurium; and the electrolyte comprises ions of the anode metal in a medium which is compatible with the anode and cathode allowing transport of the ion from anode to intercalate into the cathode. In the discharged state the battery includes a cathode characterized by the presence of A'ZAYMZX in which A' is alkali metal more electronegative than A and Z is a numerical value in the range 0< or = 3.25.
