Fiber-like VO2(B) was successfully synthesized by using V2O5 and ethanol as reactants via a magnetic stirring solvothermal process. The stirring rates significantly affected the phase, morphology and the cycling performance of as-synthesized products. When the stirring rate was 867 rpm, the fiber-like particles were 3–5 μm long and 50–100 nm wide, and showed better dispersion than the sample of VO-0, the electrochemical performance test demonstrated that the initial discharge capacity of VO-867 was 223 mAh/g, and maintained 186 mAh/g after cycling for 50 times, the retention rate of the capacity was 83.4%, which showed best cycling property of all samples.
