Surface‐amorphous and oxygen‐deficient Li 3 VO 4− δ synthesized by simple annealing of Li 3 VO 4 powders in a vacuum shows great enhancements in both reversible capacity and coulombic efficiency for the first discharge/charge without delicate size control and carbon coating. The results are associated with the improved charge‐transfer kinetics caused by the amorphous surface of Li 3 VO 4− δ .
