中文摘要：

以NiSO4、ZnSO4和Nd（NO3）3为原料，采用共沉淀快速冷冻法制备出了复合掺杂稀土Nd（III）和Zn（II）的非晶态氢氧化镍粉体材料。测试发现：样品材料微结构无序性强，结晶水含量较高。将样品材料制备成镍电极并组装成MH—Ni电池，在80mA／g恒电流充电5．5h、40mA／g恒电流放电、终止电压为1．0V的充放电制度下，复合掺杂6％Nd（III）和6％Zn（II）样品材料电池的放电平台为1．2624V，放电比容量为343．12mAh／g，远高于目前应用的B-Ni（OH）2电极活性材料的放电比容量。

英文摘要：

Amorphous nickel hydroxide eodoped in rare earth Nd （III） and Zn （II） can be synthesized by the method of quick cryoprecipition with NiSO4, ZnSO4 and Nd （ NO3 ） 3. The characterization shows that the microstructure of sample contains some crystal water,and the disordering degree is strong. A simulated MH-Ni battery composed of amorphous nickel hydroxide particles as activity material is assembled. When the sample codoped in 6% Nd（III） and 6%Zn（II） is charged at 80 mA/g for 5.5 h and discharged at 40 mA/g to a cut-off potential of 1.0 V, the discharge voltage plateau is smooth at 1. 262 4 V, the discharge specific capacity can reach as 343.12 mAh/g, higher than discharge specific capacity of β-Ni（OH） 2 electrode activity material.
