A general and simple method to synthesize well-crystallized nanostructured vanadium oxides for high performance Li-ion batteries

Abstract

A remarkably simple and effective high-temperature mixing method under hydrothermal conditions was applied to synthesize well-crystallized V₃O₇·H₂O nanobelts, VO₂ (B) nanosheets and VO₂ (A) nanorods with good performances for Li-ion batteries. In particular, V₃O₇·H₂O exhibited an excellent electrochemical performance. The outstanding electrochemical properties were explained through analysis of the crystal structures.
