Abstract
Activated carbon cloth is used as an electrode, achieving an excellent areal capacitance of 88 mF/cm(2) (8.8 mF/g) without the use of any other capacitive materials. Significantly, when it is incorporated as part of a symmetric solid-state supercapacitor device, a remarkable charge/discharge rate capability is observed; 50% of the capacitance is retained when the charging rate increases from 10 to 10,000 mV/s.
摘要
活性炭布被用作电极，在不使用任何其他电容材料的情况下，实现了出色的面电容 88 mF/cm²（8.8 mF/g）。值得注意的是，当它被纳入对称固态超级电容器装置的一部分时，观察到了显著的充放电速率能力；当充电速率从 10 增加到 10,000 mV/s 时，电容保持 50%。
