【 摘 要 】

C-MnO2was synthesized by direct hydrothermal decomposition of KMnO4. The structure and morphology of C-MnO2was characterized by XRD and SEM, electrochemical performances were investigated by cyclic voltammetry. The effects of hydrothermal temperatures, and time were systemat ically investigated. The XRD pattern can be identified as a α-types space group, and it matches well with Bragg reflection of the standard α-MnO2, suggesting that a targeted α-MnO2has been successfully synthesized. The results show that pure phase MnO2nanorods can be obtained in 160 °C. C-MnO2composites show a larger current response and C-MnO2composite material has improved the efficiency of the large current charge and discharge.
