EFFECTS OF CONSTANT-CURRENT REVERSALS DURING CHARGE OF THE SILVER OXIDE ELECTRODE,
Abstract
The sintered silver electrodes used in storage batteries were charged by a constant current, interrupted by periodic constant-current discharge. A large capacity increase was obtained when the charge current was reversed for 15 min out of every 60 min during a charge at the 20-hr rate, but this method greatly increased the total time required for a charge. Capacity could be improved a smaller amount, without charge time becoming excessive, by partly discharging the silver electrodes the first one or two times that the potential reached a chosen value near the end of a charge. In general, capacity improvement decreased as KOH concentration increased. Commercial silver-zinc cells always gave less improvement than the test cells. (Author)
