CHANGING THE DISCHARGE CAPACITY OF A SILVER OXIDE ELECTRODE BY CHARGING WITH PERIODICALLY INTERRUPTED CURRENT.
Abstract
Sintered silver electrodes were oxidized anodically in 35% to 50% KOH at 25C, usually at the 20-hr rate, sometimes at faster rates. Length of charge plus open-circuit periods varied from 8 hr to 1/60 sec. A particular charge length and open-circuit length was repeated until oxygen evolution occurred. In 50% or 45% KOH this charge method gave either the same capacity as a constant dc charge or less capacity, but in 35% KOH the improvements averaged as high as 40% under certain conditions. Best results were obtained when the preceding discharges were at low rates. (Author)
