    Beschreibung: The results of initial characterization testing of 75 Ah actively cooled bipolar battery designs and 10 boilerplate nickel-hydrogen battery designs are presented. The results demonstrate the extended cycle life capability of the Ah batteries and the high capacity utilizations at various discharge rates of the nickel-hydrogen batteries.

    Beschreibung: Three aspects of nickel electrode analysis for Nickel-Hydrogen and Nickel-Cadmium battery cell applications are addressed: (1) the determination of active material; (2) charged state nickel (as NiOOH + CoOOH); and (3) potassium ion content in the electrode. Four deloading procedures are compared for completeness of active material removal, and deloading conditions for efficient active material analyses are established. Two methods for charged state nickel analysis are compared: the current NASA procedure and a new procedure based on the oxidation of sodium oxalate by the charged material. Finally, a method for determining potassium content in an electrode sample by flame photometry is presented along with analytical results illustrating differences in potassium levels from vendor to vendor and the effects of stress testing on potassium content in the electrode. The relevance of these analytical procedures to electrode performance is reviewed.
