Surface‐Amorphous and Oxygen‐Deficient Li(3)VO(4−δ) as a Promising Anode Material for Lithium‐Ion Batteries

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 associa...

Sumario: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). [Image: see text]
