Abstract

Nitrogen-rich hierarchical porous hollow carbon nanofibers (HPCNFs) were synthesized by concentric electrospinning and subsequent KCl/K₂CO₃ activation. The obtained HPCNFs have quite high nitrogen content (14.4 wt%) and rational hierarchical porous structure, thus exhibiting a high specific capacitance of 293 F g^-1, a superior specific areal capacitance of 40 μF cm^-2 at 0.2 A g^-1 and an excellent rate capability of 62.8% (185 F g^-1) at 50 A g^-1 in 6 M KOH electrolyte.
