SILVER-ZINC SECONDARY BATTERY INVESTIGATION

Abstract

The use of palladium in the positive plate appears to increase the cycle life of silver zinc cells when cycled at 25% depth of discharge. The operation on the monovalent silver level during charge and discharge appears to be exhausted anywhere from 400 to 1000 cycles. Additional cells are under construction with 2% palladium in the positive plate to determine if operation on the monovalent voltage level can be extended in cycle life and if higher depths of discharges (40%) can be accomplished for at least 500 cycles.
