Vanadium oxynitride/vanadium trioxide nanoparticle anchored on carbon (VN 0.95 O 0.07 /V 2 O 3 @C) was prepared by one step of the annealed mixture of NH 4 VO 3 and dicyandiamide in the inert gas. As a new type of anode material for lithium-ion batteries, VN0.95O0.07/V2O3@C displays a higher specific capacity, excellent cyclic ability and rate capability. VN 0.95 O 0.07 /V 2 O 3 @C anode presents charge capacity of 800.8 mAh g −1 at the current rate of 100 mA g −1 after 100 cycles. Even at high current rate of 1.5 A g −1 , VN 0.95 O 0.07 /V 2 O 3 @C anode electrode shows high initial charge capacity of 379.4 mAh g −1 and the reversible specific capacity of 392.1 mAh g −1 after 300 cycles. The results demonstrate that VN 0.95 O 0.07 /V 2 O 3 @C based materials will be a promising candidate of anode material for LIBs after further majorization of synthesis and components. This work provides a favorable way to develop high energy and stable electrode materials for Li-ion battery.
