Abstract

Abstract

We successfully fabricated VO2(B) nanostructures through a hydrothermal process. The microstructures and the corresponding electrochemical properties of as-synthesized materials were evaluated. Experimental results indicated that the morphology of the products can be changed by modifying concentrations of the reducing agent, and the nanoflowers composed of nanobelts perform better specific capacity and cycling properties than those composed of nanoflakes. Our results show that the VO2(B) nanostructures may have potential use in the anode material of Li-ion batteries.
