Abstract

The improved method comprises electrochemically deposition of nickel hydroxide into the sintered nickel plaque cathode from nickel aqueous electrolyte at acid pH in a treating zone containing an anode. The electrochemical impregnation was examined under various conditions. Deposition condition of fine active material was obtained from the impregnation of a high temperature and also high current density. This method also could be decreased swelling and buckling of the plaque. A nickel electrode prepared by electrochemical impregnation is useful as the positive in nickel-cadmium cells. The utilization of the active material indicated almost 100% based on a one electron charge.
