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/Cr 2O3 composite materials showed that the Mn 3O4/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 Mn3O 4/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. © (2012) Trans Tech Publications.
