ELECTRODE MIGRATION AND REACTION PROCESSES OCCURRING WITHIN ALKALINE-ZINC BATTERIES.
Abstract
The cathodic zinc processes have been studied at 50 C. The limiting current density of the zinc electrode and the overvoltage for the zincate reduction were measured in 20, 30, 35, 40, and 45% KOH, each containing varying amounts of dissolved zinc oxide. The limiting current density is higher and the overvoltage is less when the zinc electrodes are amalgamated. The rate of decomposition of electrolytically formed zincate has been measured in 20, 30, 35, 40, and 45% KOH. The rate of this decomposition is greater as the amount of zincate above the equilibrium value increases, but this rate decreases as the concentration of the free hydroxide ions increases. This work was all done at room temperature. (Author)
