Investigation of battery active nickel oxides. Final report
A study of the compounds formed on a nickel oxide electrode with respect to charged stand, charge rate, state of charge and during overcharge, was made. This was done by use of x-ray diffraction, differential thermal analysis, chemical analysis, and spectroscopy. It was found that the active compounds of the electrode are essentially ..beta..-NiOOH and Ni(OH)/sub 2/ during ordinary conditions of charge and discharge. During overcharge, an unstable compound is found having the x-ray patterns of ..gamma..-NiOOH. These patterns were obtained by means of x-ray monitoring a two-plate cell during overcharge. Data for decay of this compound during open circuit stand are also presented. Differential thermal analysis indicated the existence of a compound of nickel at the graphitic level which differs from both ..beta..-NiOOH and Ni(OH)/sub 2/. Initial cycling data and testing data are also presented for sintered-plate nickel and tubular graphite types of positive plates. An experiment for stabilizing the sintered-plate nickel oxide electrode by means of formation at various rates and temperatures was started.
