ABSTRACT:
A process is described for making nickel cadmium batteries in which the cadmium electrodes for these batteries are electrolytically impregnated under special conditions and employ a particular electrolytic solution. The electrolytic solution contains not only a soluble form of the cation of the active ingredient for the electrode and nitrate ions, but also certain other ions such as chloride, iodide and sulfate ions which increase the rates of impregnation and also increase the electrode loadings. In addition to obtaining more rapid and greater electrode impregnation, the present process improvements facilitate use of a continuous impregnation procedure.
