Abstract:

A method is described for preparing coherent sponge cadmium electrodes on cadmium-plated substrates by electrodeposition from cadmium chloride solutions in the absence and presence of potassium chloride. The deposit morphology was a function of current density, pH, plating bath composition and temperature. This material had a useful capacity approximately twice that of conventional electrodes, implying a net increase in battery capacity of at least 30 if conventional sintered plate positives were used. In addition, the elimination of the sintered nickel substrate and the possibility of continuous production methods promised a lower cost. In a separate series of experiments, ultramicrotome sections of the sponge deposits were examined by transmission electron microscopy. Author
