Abstract

An electrochemical cell and method for improving voltage regulation of said cell. The cell employs lithium as an anode, lithium tetrachloroaluminate as an electrolyte, sulfur dioxide as a solvent, and high surface area carbon black containing cupric chloride as a cathode. Oxidizing agents such as halides and oxyhalides are employed to improve voltage regulation.
