Title: Lithium-lead sulfate primary electrochemical cell

Abstract: Disclosed is a primary electrochemical cell which employs a lithium metal anode, a lead sulfate cathode, and an electrolyte solution comprising a lithium salt in an organic solvent. The cell has an operating voltage and energy density sufficiently close to conventional 1.5 V cells to permit their direct replacement.
