Constructing flexible hybrid supercapacitors is a feasible way to achieve devices with high energy density, high power density and flexibility at the same time. Herein, flexible asymmetric hybrid supercapacitors are fabricated with blow spun activated carbon fibers. Owing to the highly effective conductive network, abundant nitrogen doping, optimized pore-structure and surface chemical properties of the carbon fibers, the as-prepared flexible hybrid supercapacitor shows outstanding energy and power performance (98 W h kg (0.3 mW h cm) @ 400 W kg, 9 W h kg @ 34 kW kg), as well as excellent cycle stability with 93% capacitance retention after 4000 cycles.
构建柔性混合超级电容器是一种同时实现具有高能量密度、高功率密度和柔性的器件的可行方法。在此，采用吹纺活性炭纤维制备了柔性非对称混合超级电容器。由于碳纤维具有高效的导电网络、丰富的氮掺杂、优化的孔结构和表面化学性质，所制备的柔性混合超级电容器表现出优异的能量和功率性能（在400 W/kg时为98 W h/kg（0.3 mW h/cm），在34 kW/kg时为9 W h/kg），以及出色的循环稳定性，在4000次循环后电容保持率为93%。
