Abstract
Abstract A sealed lithium electrochemical cell with sodium beta-alumina ion-conductive electrolyte is described which comprises a casing, an anode positioned within the casing, the anode selected from the class consisting of lithium, lithium as a solid alloy, and lithium in a non-aqueous electrolyte, a cathode positioned within the casing, the cathode functioning with a lithium-type anode and a solid sodium beta-alumina ion-conductive electrolyte, and a solid sodium beta-alumina ion-conductive electrolyte positioned within the casing between the anode and cathode and in contact with both the anode and cathode.
