Study of Preparation and Performance on MO/C Style Composite Electrode Materials
Preparing the MO/C style composite electrode materials by the method of coating,and the structural composition of the composite was characterized by X-ray diffraction (XRD),the electrochemical capacitive behavior of composite electrode material was investigated by cyclic voltammetry (CV) and chronopotentiometry method in 6M KOH aqueous solution additionally. Results show that composite electrode material which coated metal have most high capacitance (218.3 F/g at 0.5 A/g). In addition,composite electrode material show excellent power characteristics:the specific capacitance is as high as 168 F/g when the current density increases to 5 A/g,and the specific capacitance retains 77.0％,indicating a promising electrode material for supercapacitors.
