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 160 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
