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