摘要:超级电容器是一种新型的储能元件,超级电容器相对于传统的电容器和蓄电池来说,比电容更高,充放电速率更快,具有更长的循环寿命,使用效率更高,使用范围较广,并且对环境无污染,表现出了显著的优势。多壁碳纳米管作为一种性能优异的超级电容器电极材料,相对于其他的电极材料而言比电容较高,但是却具有难以成型的缺点,所以研究中将其与微晶纤维素进行复合,得到具有稳定形态的柔性超级电容器电极。文章最主要的部分是研究来自稻壳基等微晶纤维素与碳纳米管在不同质量比的情况下超级电容器柔性电极的电化学性能的优劣情况。通过采用电化学性能测试手段来表征微晶纤维素与碳纳米管质量比分别为1:1、2:1、4:1、6:1时相应的电化学性能,得到1:。

ABSTRACT:Super capacitor is a new type of energy ponent. Compared with traditional capacitor and battery, super capacitor showed a significant advantage. It has higher capacitance, faster charge and discharge rate, a long cycle life, wide using range. It is more effective and no pollution to the environment. Multi-walled carbon nanotube is a kind of excellent performance of super capacitor electrode material. It shows higher specific capacitance than the other electrode materials. But it is difficult to molding. So we made pounded with microcrystalline cellulose. Then they became a stable form of flexible super capacitor paper mainly researched the performance of super capacitor flexible electrode when the microcrystalline cellulose and carb
