英文摘要	Mn3O4/Cr2O3 composite materials were prepared by a chemical coprecipitation method. The structures were characterized by using SEM and XRD, and the supercapacitive behaviors of these composite materials were investigated with cyclic voltammetry (CV) and charge discharge tests. Morphology of Mn3O4/Cr2O3 composite materials showed that the Mn3O4/Cr2O3 composite materials containning a small amount of Cr2O3 has a better dispersion compared with that containning a lage amount of it. Owing to the higher surface area and poor crystallization, the Mn3O4/Cr2O3 composite materials containning a small amount of Cr2O3 show much higher specific capacitance (The highest specific capacitance value of 494 F/g was obtained), and were more promising for applications in supercapacitors.
