摘要： 用沉淀转化法制备了Ni(OH)2超微粉,并以微米级球形Ni(OH)2作对照,用循环伏安法和电化学阻抗谱研究其电化学性能,发现Ni(OH)2超微粉有更好的电化学性能。

关键词: Ni(OH)2, 超微粉, 制备, 循环伏安法, 电化学阻抗谱

Abstract: Ultrafine nickel hydroxide was prepared from NiC2O4·2H2O and NaOH in the presence of surfactant and its electrochemical behavior were compared with the micronsized spherical nickel hydroxide by CV and EIS techniques. The ultrafine nickel hydroxide prepared showed a better electrochemical property.

Key words: nickel hydroxide, ultrafine powder, preparation, cyclic voltammetry, electrochemical impedance spectrometry
