中文摘要：

通过快速冷冻沉淀法制备非晶态氢氧化镍粉体，微粒形状不规则，具有较小粒度分布和较大比表面积。经测量，发现其样品粉体拉曼光谱（Raman）峰较多，差热分析（DSC）发现其分解温度较低，为295．18℃，结果分析表明活性较高。将所制备的非晶态Ni（OH）2粉体作为活性物质合成正极材料，并组装成MH—Ni碱性模拟电池，在恒流50mA／g下充电8h，25mA／g下放电，终止电压为1．0V时，其放电工作电压平稳且时间长，放电平台为1．26v。放电比容量可达333．22mAh／g，高于β-Ni（OH）2的理论比容量289mAh／g，循环伏安曲线的测试结果表明，可逆性能较好，在碱性电解液中结构稳定。

英文摘要：

In this paper, amorphous nickel hydroxide powder was produced by the micro-emulsion rapid precipitation method. The shapes of particulates were abnormal; they had less narrow particle size distribution and bigger specific surface. It was found that there were many peaks in Raman spectrum of the sample by measurement. DSC curve indicated that amorphous nickel hydroxide had a lower decomposition temperature （about 295.18℃）, The results showed that the amorphous Ni（OH）2 has high activity. A simulated MH-Ni battery composed of amorphous nickel hydroxide particles as activity material was assembled. On the condition of charging at 50 mA/g for 8 h and discharging at 25 mA/g to a cut-offpotential of 1.0 V, the discharge voltage is calm at 1.26 V. The discharge specific capacity can reach 333.22 mAh/g, which is higher than discharge specific capacity of β-Ni（OH）2. Cyclic voltammeter curve indicates that cyclic reversibility of samples is good, and structure is stable in the alkaline electrolyte.
