제목 Commercial level mass loading three-dimensional carbon nanofibers networks for high energy density symmetric supercapacitors
초록 Rational design and development of the supercapacitor electrodes with high mass loading yet maintaining the excellent electrochemical properties are crucial. Herein, we have synthesized free-standing three-dimensional carbon nanofibers (3D-CNFs) electrode with mass loading of 35 mg/cm2 via electrospinning, sodium borohydride treatment, stabilization, and carbonization followed by the electrochemical reduction of reduction of 3D-CNFs using Na2SO4 electrolytes for 500 CV cycles. The as-reduced 3D-CNFs was used as anode and cathode while fabricating 2.0 V symmetric supercapacitors. As-constructed symmetric supercapacitors delivered energy density of 27 Wh/kg and outstanding cyclic durability. The as-fabricated device could be a potential candidate for various energy storage applicaitons.
