Carbon nanofibers (CNFs) have important application potential in the field of supercapacitors; however, the relatively low specific surface area often leads to a low capacitance. Herein, N-doped carbon nanofibers/carbon nanorods (CNFs/CNRs-N) composite with an N-doping level up to 8.9 atom % is designed, which shows excellent supercapacitor energy storage performance. CNFs/CNRs-N has a three-dimensional porous structure, a large specific surface area, and a huge number of active sites. Based on the synergy of various unique properties of CNFs/CNRs-N, when used as a supercapacitor electrode material, it shows a specific capacitance value of up to 595 F g –1 .
