Abstract：The nano-sized particles of Ni(OH)₂ are prepared by chemical deposition method. The sample is proved to be β- Ni(OH)₂ which can be used as electrode material by XRD. And the particle diameter of β-Ni (OH) are calculated about 10nm. The process parameters of the temperature, the concentration of ammonia and pHvalue for fabrication of nano-sized nickel hydroxide are optized.
