文摘
N-doping carbon nanosheets framework (N-CNF) is fabricated from cellulose acetate. The N-CNF shows an architecture like hydrogel with high specific surface area. The N-CNF exhibits excellent rate capability and high specific capacitance. A single symmetric supercapacitor easily lights 60 red light-emitting diodes.
