Three different VO2 (B) nanostructures, including urchin-like VO2 (B), VO2 (B) honeycombs and VO2 (B) nanorods have been successfully fabricated through hydrothermal process by adjusting the concentrations of the oxalic acid. The microstructure and morphology of the VO2 nanostructures were evaluated by using X-ray diffraction and scanning and transmission electron microscopies. Electrochemical properties measurements of urchin-like VO2 (B) and VO2 (B) honeycombs showed excellent cycling performance, especially the urchin-like VO2 (B) exhibited higher discharge capacity and better capacity retention.
