Electrochemical impregnation and cycle life of lightweight nickel electrodes for nickel-hydrogen cells
Author and Affiliation:
Britton, Doris L.(NASA Lewis Research Center, Cleveland, OH, United States)
Abstract: Development of a high specific energy nickel electrode is the main goal of the lightweight nickel electrode program at NASA-Lewis. The approach was to improve the nickel electrode by continuing combined in-house and contract efforts to develop a more efficient and lighter weight electrode for the nickel-hydrogen cell. Lightweight plaques are used as conductive supports for the nickel hydroxide active material. These plaques are commercial products that are fabricated into nickel electrodes by electrochemically impregnating them with active material. The electrodes are life cycle tested in a low earth orbit regime at 40 and 80 percent depths-of-discharge.
