英文摘要：

The influence of transformation pH value on the performance of nano-scale Ni（OH）2 was analyzed. The measurement results of XRD and TEM indicate that the samples are composed of β-Ni（OH）2 with crystal size of 20-50 nm, and the crystal lattice parameters of nano-scale Ni（OH）2 prepared at different transformation pH values are different. With the increase of transformation pH value, the agglomeration of nano-scale Ni（OH）2 becomes obvious. Cyclic voltammograms（CV） and electrochemical impedance spectroscopy（EIS） measurement results show that transformation pH value affects the proton diffusion coefficient（D） and charge-transfer resistance（Rot） of the material. The specific capacity is up to 327.8 mA·h/g, and the discharge performance of electrodes depends on both D and Rct, so the kinetic characteristics that electrodes reaction is controlled by both mass-transfer step and charge-transfer step was put forward.
