摘要：

Due to their cycling stability and high power density, the supercapacitors bridge the power/energy gap between traditional dielectric capacitors and batteries/fuel cells. Electrode materials are key components for making high performance supercapacitors. An activated carbon nanowhiskers (ACNWs) wrapped-on graphitized electrospun nanofiber (GENF) network (ACNWs/GENFN) with 3D porous structure is prepared as a new type of binder-free electrode material for supercapacitors. The supercapacitor based on the ACNWs/GENFN composite material displays an excellent performance with a specific capacitance of 176.5 Fg(-1) at current density of 0.5 A g(-1) an ultrahigh power density of 252.8 kW kg(-1) at current density of 800 A g(-1) and an outstanding cycling stability of no capacitance loss after 10,000 charge/discharge cycles.
