摘要：

Three-dimensional (3D) hollow-porous vanadium pentoxide (V 2O5) quasi-microspheres are synthesized by a facile solvothermal method followed by annealing at 450 °C in air. The interconnected hollow-porous networks facilitate the kinetics of lithium-ion diffusion and improve the performance of V2O5 to achieve a high capacity and remarkable rate capability as a cathode material for lithium batteries. © 2014 WILEY-VCH Verlag GmbH & Co.
