Abstract
A novel aluminum-lithium negative electrode and method for making such a novel aluminum-lithium negative electrode, including providing an admixture of aluminum powder and lithium halide electrolyte salts to form an aluminum lithium halide mixture, pressing the aluminum lithium halide mixture to form an aluminum lithium halide mixture negative electrode, placing the aluminum lithium halide mixture negative electrode next to a separate electrode composed of MgO and lithium halide electrolyte salts, providing a positive electrode of iron sulfide, lithium carbonate, and carbon, assembling the electrodes into a battery, and reacting lithium carbonate, carbon, and aluminum in situ in the battery to form an aluminum-lithium alloy negative electrode.
