摘要

通过水热法制备了钴酸铜(CuCo₂O₄)电极材料,研究了煅烧温度对CuCo₂O₄电极材料结晶度、形貌和电容性能的影响。结果表明:煅烧350℃制备的CuCo₂O₄材料的结晶度比煅烧300℃和400℃的结晶度更好;煅烧温度为350℃时,CuCo₂O₄材料呈片层状结构,片层之间交叉连接形成更多的间隙和孔道,结构更加疏松;煅烧温度为300℃和400℃时,CuCo₂O₄集聚在一起互相重叠堆积,间隙和孔道较少;煅烧温度为350℃时制备的CuCo₂O₄材料的比电容最大。

Abstract

CuCo₂O₄ electrode materials were synthesized by hydrothermal method.The effects of calcination temperature on the crystallinity,FESEM and capacitance property of CuCo₂O₄ were investigated.The results showed that the crystallinity of CuCo₂O₄ calcined at 350℃ was better than that of 300℃ and 400℃.FESEM of CuCo₂O₄ showed that the morphology of CuCo₂O₄ was lamellar structure.And cross-linking between them,more gaps and holes were formed,the structure was more loose,when the calcination temperature at 300℃ and 400℃.The layered material overlap gathered with each other,gaps and holes was less.The calcination temperature of 350℃,the specific capacitance of prepared CuCo₂O₄ material was the largest.
