Three‐dimensional (3D) hollow‐porous vanadium pentoxide (V 2 O 5 ) 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 V 2 O 5 to achieve a high capacity and remarkable rate capability as a cathode material for lithium batteries.
