1,135,218. Electrodes. WESTERN ELECTRIC CO. Inc. 16 Dec., 1965 [7 Jan., 1965], No. 53378/65. Heading H1B. A foraminous nickel electrode is activated by impregnation with nickel hydroxide, followed by at least one cycle of charge, overcharge and discharge in a carbonate (e.g. K 2 CO 3 or Na 2 CO 3 ) solution. The impregnating material, nickel hydroxide, is stated to merely promote the formation of nickel hydroxide in situ by the corrosion of the electrode per se and the amount of impregnating nickel hydroxide used bears no relation to the capacity of the electrode. The nickel electrode may be charged, overcharged and discharged in a potassium hydroxide solution either before or after activation in carbonate solution, but such a step is inessential since it occurs naturally in a battery incorporating such an electrode. Various conventional impregnating methods are mentioned. |
