Alkaline cadmium anodes have been developed to deliver 0.30 ampere-hours per gram of electrode at the C5 rate. These anodes are of the sponge type and maintain 80-85 of theoretical capacity when continuously cycled at 100 depth of discharge C5 rates of charge and discharge at room temperature. Loss of capacity of the cadmium anode is prevented by a employment of 5-10 Fe2O3 or TiO2 extender, b elimination of carbonate within the unit cell, c moderate overcharging during initial cycling, and d charging at rates between C5 and C2. Shorting by cadmium penetration through the separator system is prevented by a elimination of carbonate within the unit cell, b the employment of bibulous inert interseparators between the anode and main separator, and c keeping overcharge to a minimum.
