Preparation of β-NiOOH and Its Charge/Discharge Performance
Abstract:
U-NiOOH was prepared by chemical oxidation of U-Ni(OH)2. The physical characteristics and the chemical composition of the product were characterized by XRD, TG/DTA and ICP measurements. U-NiOOH and the mixed samples of U-NiOOH with V-MnO2 in different ratios were charged/discharged in constant current, the results show that the addition of V-MnO2 improves the discharge voltage plateau of nickel electrode and the optimum ratio of V-MnO2 in the electrode is 25%. The cut off voltage of nickel electrode should be above 0V(vs.Hg/HgO).
