采用浸渍-水热沉淀法合成CuO掺杂Ni（OH）2前驱体,经300℃煅烧得NiO-CuO复合氧化物。利用FT-IR、XRD、SEM和恒流充放电分析测试复合材料的相结构、微观形貌和电化学性能。结果表明,当镍铜比为4∶1时,在5mA/cm2的电流密度下所得复合氧化物单电极比电容为822F/g,180次循环后衰减率仅为4.5%,循环可逆性能好。

Nickel hydroxide doped with copper oxide were synthesized by dipping at hydrothermal process.They were annealed in air 300℃ to obtain composite oxide.The samples of phase structure,micro-cosmic morphology and electrochemical properties were characterized by FT-IR,XRD,SEM and constant-current charge-discharge testing techniques.The results showed that the specific capacitance of the NiO-CuO obtained after calcination as a single electrode was up to 822F/g to 5mA/cm2 discharge when nickel copper than for 4∶1.Then the attenuation rate was only 4.5% after 180 cycle.
