Abstract
A solid state electrochemical cell 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, or alloys of lithium with indium or thallium, a cathode positioned within the casing, the cathode comprising a non-stoichiometric lithium compound in which the composition can be expressed by the formula Li.sub.x M.sub.y O.sub.z wherein the subscript x is in the range 0<x<1, M is a cation which can change its oxidation state in accordance with the value of x, the subscript y is in the range 0<y.ltoreq.3, and z has a value such that electrical neutrality of the compound is established, 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.9Al.sub.2 O.sub.3 of which 1.3 to 85.0% of the total alkali ion content is lithium.
