英文摘要	Both vanadium nitride and carbon are the important negative materials for capacitors electrodes, while effectively dispersing vanadium nitride into the surface of carbon materials would highly enhance the utilization of active materials. In this article, we find out a valid dispersion method of vanadium nitride nanoparticles into the porous carbon networks, which is derived from a synthesized block copolymer of polyacrylonitrile-b-poly[2-(methacryloyloxy)ethyl]trimethylarnmoriiurn. chloride-b-polyacrylonitriletogether with the absorbed ammOrdurn, metavanadate. With the superiority of the designed structure, the fabriCated materials are used' as negative materials for capacitors electrodes and show outstanding electrocheinical performance with a specific capacitance of 195.7 F/g and a prior cycle stability of 75% retention. In addition, 'the effect of the ratio of copolymer to ammonium metavanadate on the electrochemical performance of the product is also investigated in detail.
