摘要: |
A series of activated carbons with high mesoporous ratio were prepared by KOH reactivation based on activated carbon as the precursor. As the KOH/AC mass ratio was increased to 4:1, the mesoporous ratio increases from 60% to 76%, and the average pore size from 2.23 to 3.14 nm. Moreover, the specific capacitance for the activated carbon in ionic liquid 1-ethyl-3-methylmidazolium tetrafluoroborate ([EMIm]BF(4)) can reach the maximum value of 189 F g(-1) (8.0 mu F cm(-2)). In addition, the decrease of specific capacitance for activated carbons by KOH reactivation with current density increase shows two regimes, suggesting that activated carbons with high mesoporous ratio are much fit for charge-discharge at larger current density. |
