摘　　要：采用溶剂热法制备了超级电容器锰酸钴(CoMn2O4)电极材料.通过X线衍射(XRD)和扫描电子显微镜(SEM)对材料进行表征.XRD测试结果表明,样品为CoMn2O4.SEM结果显示,所制得的CoMn2O4在亚微米到微米尺度下形成花形团簇.电化学性能测试表明,CoMn2O4电极的比电容可达到179 F/g,且具有良好的电化学性能.Electrode material of CoMn2 04 was prepared through solvothermal process and characterized by X-ray diffraction（XRD） and scanning electron microscope （SEM）. The XRD result shows that the obtained sample is CoMn2O4. The SEM result shows that CoMn2O4 presents flower-like clusters in sub- micron and micron sizes. The results of electrochemical tests show that the specific capacitance of the CoMn2O4 electrode can arrive 179 F/g with good electrochemical property.
