Abstract

An electrochemical storage cell or battery with one anode chamber containing molten alkali metal as the anolyte and one cathode chamber containing sulfur-containing catholyte substance, the anolyte and catholyte separated by an alkali-ion-conducting solid electrolyte. The cathode chamber is bounded by a cellwall having a protective layer of a light weight metal also serving as a current collector. The light weight metal in the regions in contact with the catholyte is coated with a metallic alloy which under conditions of operation has certain properties of adhesion, conduction, resistance, corrosion and solubility.
