nickel-cadmium battery

The development of nickel-cadmium batteries with high energy capacious electrodes is described. Selection and development of technology of manufacturing nickel-oxide electrodes based on nickel-plated carbon and graphite felt materials are considered. Discharge characteristics of the electrodes are analysed.

The possible mechanisms of cadmium shunting in nickel-cadmium batteries are analyzed. The transfer of the negative elektrode active mass to the interelectrode gap is shown to be the main cause leading to a short circuit. The complete or partial cathodic reduction of this mass results in the separator loosing its insulating ability and in an internal short circuit.
