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. |
