Chronopotentiometric Measurements of Zinc Electrodeposition Kinetics from Concentrated KOH Solutions.
Abstract
In order to improve the efficiency of zinc-silver oxide cells, it consequently is desirable to examine the kinetics of zinc electrodeposition from the KOH electrolyte used in spacecraft cells. It was thought that chronopotentiometry would have the greatest probability of successful application to the caustic 41% KOH electrolyte containing 1 M ZnO solute, which is used in zinc-silver oxide cells. Chronopotentiometry was accordingly applied to compare the kinetics of zinc electrodeposition on zinc and amalgamated zinc electrodes (which are used in zinc-silver oxide storage batteries) with the kinetics for electrodeposition on nickel, lead, copper, tin, silver, gold, mercury-film, and platinum electrodes. The chronopotentiometric technique was also applied to investigate the effect of lead ion additives on zinc electrodeposition and to examine wetting agent effects on zinc electrodeposition.
