Abstract
Three-dimensional V2O5 hollow structures have been prepared through a simple
synthesis strategy combining solvothermal treatment and a subsequent thermal annealing. The V2O5
materials are composed of microspheres 2–3 m in diameter and with a distinct hollow interior.
The as-synthesized V2O5 hollow microspheres, when evaluated as a cathode material for lithium-ion
batteries, can deliver a specific capacity as high as 273 mAh g���1 at 0.2 C. Benefiting from the hollow
structures that afford fast electrolyte transport and volume accommodation, the V2O5 cathode also
exhibits a superior rate capability and excellent cycling stability. The good Li-ion storage performance
demonstrates the great potential of this unique V2O5 hollow material as a high-performance cathode
for lithium-ion batteries.
