ABSTRACT:
A sealed lithium-reducible metal salt cell for ambient temperature operation is described which comprises a casing, an anode positioned within the casing, the anode selected from the class consisting of lithium, lithium as an amalgam, and lithium in a nonaqueous electrolyte, a cathode positioned within the casing, the cathode comprising a reducible metal salt in a nonaqueous electrolyte with an ionic conductivity enhancing material, 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 LiNaO.sup.. 9Al.sub.2 O.sub.3 of which 1.3 to 85% of the total alkali ion content is lithium.
