In this work, a N-doped-carbon-nanofiber (NCNF)-supported Fe₃C/Fe₂O₃ nanoparticle (NCFCO) composite was synthesized via the facile carbonizing and subsequent annealing of electrospinning nanofibers containing an Fe source. In the hybrid structure, the porous carbon nanofibers used as a substrate could provide fast electron and ion transport for the Faradic reactions of Fe₃C/Fe₂O₃ during charge-discharge cycling. The as-obtained NCFCO yields a high specific capacitance of 590.1 F g^-1 at 2 A g^-1, superior to that of NCNF-supported Fe₃C nanoparticles (NCFC, 261.7 F g^-1), and NCNFs/Fe₂O₃ (NCFO, 398.3 F g^-1). The asymmetric supercapacitor, which was assembled using the NCFCO anode and activated carbon cathode, delivered a large energy density of 14.2 Wh kg^-1 at 800 W kg^-1. Additionally, it demonstrated an impressive capacitance retention of 96.7%, even after 10,000 cycles. The superior electrochemical performance can be ascribed to the synergistic contributions of NCNF and Fe₃C/Fe₂O₃.
