Abstract

Mesoporous V2O5 nanofibers were fabricated by a method combining sol–gel processing with electrospinning followed by annealing in air. The resultant nanofibers were 350 nm in diameter and consisted of porous polycrystalline vanadium oxide with a specific surface area of ∼97 m2 g−1. The mesoporous V2O5 nanofibers demonstrated a significantly enhanced Li ion storage capacity of above 370 mA h g−1 and a high charge/discharge rate of up to 800 mA g−1 with little cyclic degradation.
