Title: Electrochemical cell

Abstract: An alkaline electrochemical cell having an anode containing zinc and a cathode that includes a catalyst and an iodate is disclosed. The catalyst catalyzes the reduction of the iodate when the cell is discharged thereby enabling the cell to be used in devices that have a functional endpoint of 1.0V or higher. Preferred catalysts include platinum and palladium. Suitable iodates include copper iodate, strontium iodate and lead iodate.
