Sintered cadmium electrodes for alkaline batteries

The electrochemical behaviour of sintered cadmium electrode in 6N KOH electrolyte has been investigated by cyclic voltammetry. The anodic and cathodic curves were recorded at different sweep rates and the peaks were associated with the electrooxidation and electroreduction processes which occurred. The performances of sintered cadmium electrodes (70 x 35 x 1 mm) were investigated in a half-cell by charge-discharge curves. The different forms of active material (uncycled, charged and discharged) were characterized by X-ray diffraction.
