Abstract
This invention provides a method of making a cathode for a high temperature rechargeable electrochemical cell. A mixture is formed in particulate form of an alkali metal chloride such as sodium chloride and a substance comprising a transition metal such as iron, and the mixture is impregnated with a chloride ion-containing alkali metal aluminium halide molten salt liquid electrolyte such as molten sodium aluminium chloride. The impregnated mixture is then subjected to at least one charge cycle in a high temperature cell in which it forms the cathode and is separated from an alkali metal anode by a solid electrolyte separator.
