摘　　要：本文以三水合硝酸铜、六水合硝酸钴分别作为铜源和钴源,通过水热法和离子交换法成功合成了铜钴氧化物和铜钴硫化物。SEM结果显示铜钴硫化物和铜钴硫化物都具有纳米花状结构。其中,铜钴硫化物的纳米薄片更薄,大约为40~50 nm,团聚现象更低。用恒电流法测得在1.0 A/g的放电电流密度下,其比容可达572 F/g。在2.0 A/g的放电电流密度下循环3000次,其容量保持率可达77%。In this article, as the Copper nitrate trihydrate and Cobalt nitrate hexahydrate for the source of Cooper and Cobalt respectively, We successfully synthesized cooper cobalt oxide and cooper cobalt sulfide via the process of hydrothermal and ion exchange method. The sem results show that both copper cobalt oxide and copper cobalt sulfide possess the nano-flower structure. Especially, the nanosheets of copper cobalt sulfide are approximately 40 nm to 50 nm thickness which more thinner than the nanosheets of cooper cobalt oxide. The nanosheets of copper cobalt sulfide grown in different oritentions show less phenomenon of agglomeration. The specific capacitance of copper cobalt sulfide can reach 572 F/g. At the curent density of 1 A/g by galvanostatic charge-discharge test. After 3000 cycles, the specific capacitance retention of copper cobalt sulfide is 77 %.
