Abstract

Three-dimensional (3D) porous vanadium pentoxide (V₂O₅) thin films were synthesized by electrostatic spray deposition followed by annealing at 350 °C in air. The interconnected pore networks facilitate the kinetics of lithium-ion diffusion and help the porous V₂O₅ with stable capacity, high energy efficiency and excellent rate capability as a cathode material for lithium batteries.
