纳米氢氧化镍的研制及其电化学性能

Preparation of Nano-nickel Hydroxide and its Electrochemical Performance

采用沉淀转化法制备出纳米氢氧化镍 ,并对表面活性剂和温度两个因素作了较细致的研究。XRD和TEM测试结果表明 :样品为球形或椭球形 ,直径 3 0～ 60nm ,晶型为 β型。将样品掺杂到氢氧化镍电极中可使氢氧化镍利用率提高 1 0

Nano scale nickel hydroxide is prepared through sedimentation transform method in this paper. And the effect of the concentration of surfactant and temperature on material is investigated. The measurement results of XRD and TEM indicate that the crystallization of the nano scale nickel hydroxide is β form and its shape is spherical with a diameter of 30～60 nm. The utilization ratio of Ni(OH) 2 can be raised by 10% when the nano scale nickel hydroxide is added in common nickel hydroxide with a ratio of 8%.\;
