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

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