Liquid metal electrodes in secondary batteries

The present effort is directed mainly toward cells with solid lithium alloy (e.g., Li-Al, Li-Si) negative electrodes and metal sulfide positive electrodes. The current research and development work on sodium electrode batteries involves a liquid sodium electrode; a solid, ion-conducting electrolyte; and a liquid sulfur or metal chloride positive electrode. Both types of systems show promise for the electric automobile and load leveling applications.
