STATE-OF-THE-ART ALKALINE CADMIUM ANODES.
Abstract
Alkaline cadmium anodes have been developed to deliver 0.30 ampere-hours per gram of electrode at the C/5 rate. These anodes are of the sponge type and maintain 80-85% of theoretical capacity when continuously cycled at 100% depth of discharge (C/5 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 C/5 and C/2. 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.
