Simply fabricating F-doped V2O3 nanoparticles adhered to N-doped carbon as a high-rate anode

F-doped V2O3 nanoparticles/N-doped carbon composite was initially synthesized and applied as a high-rate anode material for LIBs. [Display omitted] •F-doped V2O3/N-doped carbon composite is prepared for the first time.•Doping F and combined with NC bring fast electrochemical reaction kinetics.•F-V2O3/NC anode shows excellent rate performance and cyclic stability.•High capacity of 481 mA h/g is achieved at 2 A/g. The development and application of V2O3-based anodes are hindered by their poor reversible capacity and rate performance. Doping F and combined with N-doped carbon at the same time would achieve excellent electrochemical performance, but the related materials are not prepared and employed to lithium-ion batteries due to the absent synthetic method. In this investigation, a simple strategy was firstly invented to achieve F-doped V2O3/N-doped carbon composite. The F-doped V2O3 nanoparticles are adhered to N-doped carbon, which would enhance electrochemical reaction kinetics. As a result, a high capacity of 481 mAh/g can be obtained at 2 A/g.
