Abstract | Vanadium oxide@vanadium carbide (VxOy@VxC) composites with a core-shell structure was constructed via a simple in-situ oxidation method, i.e. by oxidizing V2C precursor at 350-400 degrees C for 1 h under air atmosphere. As obtained VxOy@VxC composites are in the submicro-sized particle distribution. These VxOy@VxC composites have displayed remarkable electrochemical performances as anodes in lithium-ion batteries (LIBs), thereinto V2O5@VO2@V2C@VC composite exhibits the most impressive cycling stability, releasing-252.1 mAh g(-1) after 200 cycles at 0.5 A g(-1) with capacity retention of 89.5% and-492 mAh g(-1) in the continuous 120 cycles at 0.1 A g(-1). Such an outstanding electrochemical performance could benefit from the unique core-shell heterostructure of VxC encapsulated by VxOy, with an excellent structural stability. It is favorable to provide the excellent charge transfer field and effectively restrain the aggregation and structural deformation during the electrochemical reaction process. This design of V2O5@VO2@V2C@VC composite is promising for motivating the development of anode materials in LIBs. |
