Characterization and cycle tests of lightweight nickel electrodes

Development of a high specific energy nickel electrode is the main goal of the lightweight nickel electrode program at NASA Lewis Research Center. 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 battery. High energy nickel electrodes suffer from having shorter lives than state-of-the-art electrode. However, these lightweight electrodes appear to be favorable for missions requiring moderate cycle lives and depth-of-discharge.
