ABSTRACT:
A sealed lithium-sodium electrochemical cell is described which comprises a casing, an anode positioned within the casing, the anode selected from the class consisting of lithium-sodium, lithium-sodium as an amalgam, and lithium-sodium in a non-aqueous electrolyte, a cathode positioned within the casing, the cathode functioning with a lithium-sodium type anode and a solid lithium-sodium aluminate electrolyte, and a solid lithium-sodium aluminate electrolyte positioned within the casing between the anode and cathode and in contact with both the anode and cathode, the solid lithium-sodium aluminate electrolyte having an approximate composition of LiNa0.9Al.sub.2 O.sub.3 of which 1.3 to 85% of the total alkali ion content is lithium.
