ABSTRACT:
A high energy density electrochemical cell comprises an anode consisting essentially between about 63% and 92% lithium, on an atomic basis, and the balance essentially aluminum, a cathode and a nonaqueous electrolyte. Advantageously, the cathode is an electrochemically active transition metal chalcogenide, such as titanium disulfide, and the nonaqueous electrolyte is an organic solvent, such as dioxolane, having at least one lithium salt, preferably lithium perchlorate, dissolved therein.
