Vanadium pentoxide (V2O5) hollow microspheres with mesoporous shells were prepared by a solvothermal process followed by a high-temperature calcination step in air. The as-prepared hollow microspheres exhibit mesoporous structure on the shells, which provide channels for electrolyte transfer and show excellent lithium storage properties for lithium-ion batteries. The electrochemical performances of formed V2O5 porous-hollow microsphere anodes were investigated and analyzed. Among the formed samples, integral V2O5 hollow microspheres with mesoporous shells achieved a reversible capacity of 710.2 mA h g−1 after 400 cycles at a current density of 0.5 A g−1. The results demonstrate an ascendant electrochemical characteristic of as-prepared V2O5 hollow microspheres with mesoporous shells for the energy storage devices.
