| 中文摘要 | gamma-MnO2 was synthesized by reducing KMnO4 with H2O2, and then calcined at various temperatures. The physical properties of the samples were examined TG-DSC, SEM, PSD, X-ray diffraction and FTIR. The effects of calcination temperature on the electrochemical performance of the samples were investigated by galvanostatic discharge, cyclic voltammetry and electrochemical impedance spectroscopy. The results show that calcination has definite effects on the crystal structure and electrochemical performance of the samples. The sample treated at 473 K a larger discharge capacity and higher discharge potential than the others, and its specific discharge capacity is 36.8% higher than commercial MnO2. |
