Abstract: A rechargeable, self-heating aluminum-chalcogen battery is provided, with an aluminum or aluminum alloy negative electrode, a positive electrode of elemental chalcogen, and a mixture of chloride salts providing a molten salt electrolyte. The predominant chloride salt in the electrolyte is AlCl3. Additional chloride salts are chosen from alkali metal chlorides. The cell operates at a modestly elevated temperatures, ranging from 90° C. to 250° C.
