Abstract：Manganese compounds are used as high-capacity electrode materials for supercapacitor Micro/nanostructure materials have the advantages of both nano-materials and micro-materials. In this paper,MnCO3were prepared by hydrothermal method,which transferred to Mn2O3after heat treatment at 600 ℃ in air.The structure and morphology analysis show that MnCO3micro spheres are comprised with nanosized cubic.Mn2O3microspheres are constructed by nanosized particles.After mixing with Super P with different ratio,the electrochemical properties of Mn-CO3and Mn2O3were studied.The results exhibit that the specific capacitances of MnCO3and Mn2O3are significantly enhanced by mixing with Super P.When the ratio is 9:1,the maximum capacitance of MnCO3/Super P can reach 207 F·g-1,which is much higher than Mn2O3/Super P.
