An investigation of new cell components for vented nickel-cadmium batteries shows that it is possible to prevent capacity loss due to crystal growth of cadmium and cadmium hydroxide by the addition of 1 indium hydroxide to the active cadmium powder. Cadmium anodes with 5 nickel hydroxide were found to be partially effective in resisting crystal growth. The investigation also shows that the low temperature performance of vented nickel-cadmium cells -20F with methacrylic acid-grafted polyethylene membranes, E-2291 4020, is equal to that of cells with standard cellophane membranes if the former are initially formed by means of an optimized pulse mode of charging based on USAF data, the room temperature life of vented nickel-cadmium batteries with E-2291 separator is about five times greater than standard batteries with cellophane membranes.
