Nano-particles Ni(OH)₂ were prepared from PEG solution of Ni(NO₃)₂ by chemical precipitation method and characterized by XRD and TEM techniques. The results indicated the sample is nano-phase β-Ni(OH)₂ with average size of 48 nm. The gavanostatic charge-discharge test and the cyclic voltammetry demonstrated the resultant sample has a higher electrochemical activity. Its specific capacity reaches 96.5% of the ideal capacity and stronger anti-overchargeability.
