New alkaline battery electrodes used in cells such as nickel oxide--cadmium, nickel oxide--hydrogen, nickel oxide--zinc, and silver oxide--zinc were developed as a result of contracted and in-house research at the Air Force Aero-Propulsion Laboratory. Cathodic hydroxide precipitation techniques are used for preparation of nickel oxide and cadmium electrodes. Bipolar silver oxide--zinc electrodes are fabricated by spray deposition-sintering and vapor deposition techniques. Novel methods for preparation of dry-charged nickel oxide electrodes for reserve-type nickel oxide--zinc batteries are being investigated. One technique involves charging conventional sintered, vacuum-impregnated electrodes, then removing electrolyte with a distilled water wash. Drying is performed in vacuo. The plates yield rated capacity upon activation, but on long-term dry storage data are available. Secondary nickel oxide electrodes, prepared by cathodic precipitation techniques, appear far superior to other nickel oxide electrodes because of their reduced thickening with charge--discharge cycling at deep depths of discharge and their good charge acceptance at high temperatures. The silver oxide--zinc electrode fabrication techniques made construction of a multicell pile for high-power applications feasible. Minor problems such as anomalous gassing were incurred but appear capable of solution.
