Abstract

Abstract:

Activated carbon/manganese oxide (MnOx) composites were prepared by the thermal decomposition of Mn(NO₃)₂ that was impregnated on the surface of activated carbon XC-72 with a specific surface area of 250 m²·g^-1 and on YEC-8 with a specific surface area of 1726 m²·g^-1 at 200 ℃. The surface morphology and crystalline structure of the composites were investigated using scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The electrochemical properties of the composites were tested by cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy. We found that α-Mn₂O₃ and α-Mn₃O₄ were formed when the composites were annealed at 200 ℃. At mass ratios of C and MnOx of 2∶1 and 9∶1, the specific capacitance of MnO_x in the composites of XC-72/MnO_x was 499 and 435 F·g^-1 and the specific capacitance of MnOx in the composites of YEC-8/MnO_x was 554 and 606 F·g^-1, respectively. This suggests a significant contribution of pseudocapacitance from MnOx to the specific capacitance of the electrode.
