Abstract
A sealed lithium-type electrochemical cell is described which comprises a casing, a lithium-type anode positioned within the casing, a cathode positioned within the casing, the cathode functioning with a lithium-type anode and a solid lithium-sodium beta"-alumina electrolyte, and a solid lithium-sodium beta"-alumina electrolyte positioned within the casing between the anode and cathode and in contact with both the anode and cathode.
Claims4
A sealed lithium electrochemical cell comprising a casing, an anode positioned within the casing, the anode selected from the class consisting of lithium, lithium as an amalgam, lithium in a non-aqueous electrolyte, a lithium-alloy with from 1.0 weight percent to 99.0 weight percent lithium, a lithium-alloy as an amalgam, and a lithium alloy in a non-aqueous electrolyte, a cathode positioned within the casing, the cathode functioning with the anode, a solid lithium-sodium beta"-alumina electrolyte positioned within the casing between the anode and the cathode, the solid lithium-sodium beta"-alumina having the formula
- y(LiNa)O.nX.5Al.sub.2 O.sub.3
- wherein y is a range from 0.55 to 1.0;
- X is an oxide selected from the group consisting of MgO, Li.sub.2 O, m(MgO)p(Li.sub.2 O) wherein the total of m and p equal n;
- n is a range from 0 to 1.0;
- and 1.0 to 99.0 percent of the total alkali ion content is lithium.
