| Abstract: | In this study, Carbon microcoils (CMCs) have been coated by MnO2 using an electrophoresis deposition (EPD) method. The morphology and structure of the composites are characterized by SEM, Raman and XPS, respectively, and their electrochemical properties are also investigated. The experimental results show a specific capacitance of 115 F·g-1 at a scan rate of 5 mV·s-1. Moreover, it retains 96.7 F·g-1 (89.5%) at current density of 0.2 A·g-1 after 200 cycles, which illustrates its good cycling stability. |
