✦ Synopsis

The oxygen recombination (reduction) rate on plastic-bonded cadmium electrodes in sealed Ni-Cd systems can be increased by using metal screens applied to the gas side of the plastic-bonded cadmium electrode.

The metal screen applied should have an optimum geometry (mesh size, wire diameter) to provide optimum conditions for the existence of a uniform electrolyte film covering the total screen surface. The oxygen recombination rate in such a case is high enough to enable this type of cadmium electrode to be used in practical sealed cells.

No major differences between steel and nickel screens were noticed, but with a silver plated screen a substantially enhanced oxygen recombination rate was observed.

The rate of oxygen recombination (i.e., reduction) on plastic-bonded cadmium electrodes in sealed Ni-Cd systems can be controlled over a wide range by doping the negative active material with Ni(OH),, FeaOb or carbon black. The highest recombination rate was attained by combining all these additives

It was found that the rate of reduction of oxygen on plastic-bonded cadmium electrodes doped with Nl(OH), is highest when the added nickel amounts to 0.3%. If the active material 1s in prolonged contact with a solution of NISOq and then alkahzed, its oxygen reduction activity is appreciably lowered,
