摘　　要：NiOOH was prepared by chemical oxidation of β Ni(OH) 2. The physical 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 MnO 2 in different ratios were charged/discharged in constant current, the results show that the addition of γ MnO 2 improves the discharge voltage plateau of nickel electrode and the optimum ratio of γ MnO 2 in the electrode is 25%. The cut off voltage of nickel electrode should be above 0 V( vs .Hg/HgO).NiOOH was prepared by chemical oxidation of β Ni(OH) 2.
