A Novel Substrate for Nickel Cadmium Batteries

Although the nickel-cadmium battery is accepted as the rechargeable system for applications where size and weight are crucial, its electrode substrate accounts for about 40% of the battery weight. A new fibrous nickel substrate, Fibrex, has become available that offers a potential of 50% reduction in the weight of the electrode substrate and a corresponding 20% gain in energy density. Thus it is desirable to determine whether this substrate is a good material for the Ni/Cd battery.
