Nickel doped Li3VO4 nanocrystallites with high surface energy showed excellent lithium ion storage property with a capacity of 650 mAh g−1 at 50 mAh g−1 and excellent capacity stability as anode in lithium ion batteries. The nickel doping promoted the formation of V4+ and more amorphous in the surface of Li3VO4, probably resulting in higher surface energy, more nucleation sites for the phase transformation and reducing the activation energy of the redox reactions and phase transition during the Li+ intercalation/extraction processes.
