摘要: Abstract Hierarchically porous carbon with micropores, mesopores, macropores and high specific surface area for supercapacitors is fabricated from an aqueous curable composition by curing subsequent carbonization, followed KOH activation under N 2 atmosphere. With the manipulation of to peculiar morphology developed during external grows 208 1151 m g −1 , while micropores stays at around 1100 m leading micro/external ratio decreases 5.36 0.94. Prepared KOH/carbon weight 2.0, total 1590 m moderate about exhibits intriguing electrochemical performance in 1 M H SO 4 electrolyte, such as superior capacitance (274 F g 0.1 A g ), excellent rate capability (161 F g remained 20 A g ) outstanding cycling stability (no loss over 5000 cycles). The promising could be attributed synergy hierarchically area.
