The feasibility of a room‐temperature, nonaqueous organic solvent, electrochemical cell that can deliver 10 mA/cm2 at 4V has been demonstrated. The cell consists of a lithium negative, a graphite compound positive electrode, and a lithium perchlorate‐dimethyl sulfite electrolyte solution. The cell develops an open‐circuit potential of approximately 4.5V. Apparently the lithium perchlorate‐dimethyl sulfite electrolyte undergoes no or least slow oxidation or reduction within a 4.5V range.
