摘要
用化学方法在无水乙醇溶剂中制备出纳米级Ｎｉ（ＯＨ）２，对其进行ＸＲＤ、ＴＥＭ分析，证实样品是纳米级β－Ｎｉ－（ＯＨ）２，将常规用Ｎｉ（ＯＨ）２和纳米级Ｎｉ（ＯＨ）２以一定比例混合的充放电循环测试结果表明，放电容量增大，对其又进行了循环伏安、恒电位阶跃、Ｔａｆｅｌ极化曲线的测试，初步解释了作为纳米材料在电化学应用中所表现出的性质。
Nano phas nickel hydroxide 〔Ni(OH) 2〕 was prepared in anhydrous ethanol by chemical method,The measurements,such as XRD,TEM etc.were carried out and the results proved that the sample was nano phase Ni(OH) 2.The discharge capacity has been increased dramatically by mixing the conventional β Ni(OH) 2 with the nm β Ni(OH) 2 at an optimum weight ratio.The results can be explained by cyclic voltammetry,constant potential step and Tafel curves experiments.
