Abstract: β-Ni(OH)2 nano-particles were produced by homogeneous precipitation method and anhydrous ethanol method. The Characteristics of the nano particles were studied by XRD, TG, DTA,TEM and ICP. It was found that the effect of main factors including the kind of surface activeagent, the transform condition of crystal type and the aftertreatment temperature, on the sampleperformance was great. The performance of the charge/discharge cycles was also studied.

Key words: nano-particles, β-Ni（OH）2, homogeneous precipitation, suface active agent
