| 摘要: 利用电泳沉积法(EPD)制备碳螺旋纤维基MnO2@CMC复合材料，采用电子扫描电镜、拉曼光谱(Raman)、X射线光电子能谱(XPS)对其形貌和结构进行表征并测试其电容性能，结果显示：当电位差扫描速率为5 mV·s-1时，充放电容量较高，可达115 F·g-1，在0.2 A·g-1的扫描电流下，循环200圈后电容量为96.7 F·g-1，为起始电容量的89.5%，表现出良好的电容保持率和循环稳定性。 |

| 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. |
