Abstract

Surface-amorphous and oxygen-deficient Li₃VO_4−δsynthesized by simple annealing of Li₃VO₄ 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 Li₃VO_4−δ.
