Abstract

The effect of some organic additives on the capacity performance of pressed pellet and sintered plate type cadmium electrodes has been studied. The additives under investigation are benzimidazole and polyvinyl alcohol. The organic electrode additives for the cadmium electrode of the nickel-cadmium battery is aimed mainly for increasing the discharge capacity and minimising the self discharge. It is found that pressed electrode can be used for low rates of discharge whereas the sintered electrodes can be used for both low and high rates of discharge. It is found that pressed electrode can be used for low rates of discharge whereas the sintered electrodes can be used for both low and high rates of discharge. The organic additive sources show better low and high rate performance for sintered cadmium electrodes.
