Abstract
Problems arise with nickel/cadmium aircraft batteries as a result of deterioration of the conventional cellophane barrier layer in the separators. The cellophane deteriorates especially rapidly in the cells at elevated temperatures. Tests have shown that Celgard, a polypropylene microporous polymeric film manufactured by the Celanese Plastics Company, can be substituted for the cellophane and can readily withstand the oxidizing environment in the cell even at elevated temperatures.
