Abstract
A method of making a cathode for a high temperature rechargeable electrochemical cell comprises impregnating a mixture, in granular form, of an alkali metal halide and a substance comprising a transition metal selected from the group consisting of iron, nickel, cobalt, chromium, manganese, and mixtures thereof, with an alkali metal aluminium halide molten salt electrolyte. The impregnated mixture is subjected to at least one charge cycle in a high temperature electrochemical cell in which the impregnated mixture forms the cathode and is located in a cathode compartment of the cell. The cathode compartment is separated from an anode compartment by a solid electrolyte separator. Alkali metal forms in the anode compartment during the charge cycle.
