Abstract : The reduction of Cd(OH)2 to cadmium at the nickel electrode in the NiCd cell has been found to compete with the hydrogen evolution reaction during cell reversal. This reduction reaction can lead to internal short circuits as cadmium dendrites bridge the separator. The cadmium metal short circuits are reoxidized when the cell is recharged and do not appear to have a significant short-term effect on cell performance. (Author)
