摘要：
The impedance spectra of Zr(V0.4Ni0.6)(2), Zr(V0.2Mn0.2Ni0.6)(2), Zr(V0.2Mn0.2Ni0.55Si0.05)(2) alloys have been investigated An equivalent circuit for the reaction of an MH electrode is proposed The results reveal that: (1) the additions of Mn and Si have significant effects on the reaction resistances of the alloys; (2) Ni powder is an appropriate additive material in the manufacturing process of an MH electrode; (3) the amounts of Ni powder in the alloy electrode also should be considered in the practical utilisation.
