中文摘要：

以柠檬酸三钠为络合剂，采用络合反应快速冷冻共沉淀法制备出铜掺杂氢氧化镍超细粉体样品材料，采用XRD、SEM、TEM、TG—DSC、Raman和红外对其进行表征，同时将其作为正极活性材料组装成MH—Ni电池，测试了其电化学性能。充放电结果表明，样品电极具有较好的循环特性．当Cu的掺杂量为5％时，合活性物质80％的样品电极在恒流80mA／g下充电6h，40mA／g放电，终止电压为1．0V时．放电电压稳定于1．260V的时间较长，开路电位为1．462V，放电比容量可达362．976mAh／g，表现出其较高的电化学活性。

英文摘要：

Cu-substituted amorphous nanometer-level nickel hydroxide powder have been prepared by the method of coordination-precipitate with sodium citrate as complexant. The powers were characterised by XRD,SEM,TEM, Raman, TG-DSCand IR, and the electrochemical properties was tested by using a simulated MH-Ni battery composed of amorphous nanometer-level nickel hydroxide particles as activity material When the sample electrodes with 80% active substance which has 5% Cu was charged at 80mA/g for 6 h and discharged at 40mA/g to 1.0V ,the sample has longer discharge time at 1.260v,and the discharge specific capacity can be reached as high as 362.976mAh/g, and it shows great electrochemical performances.
