Self-assembled sandwich-like vanadium oxide/graphene mesoporous composite as high-capacity anode material for lithium ion batteries

Journal Article


Abstract


  • Sandwich-like V2O5/graphene mesoporous composite has been synthesized by a facile solvothermal approach. The crystalline structure, morphology, and electrochemical performance of the as-prepared materials have been investigated in detail. The results demonstrate that the 30-50 nm V2O5 particles are homogeneously anchored on conducting graphene sheets, which allow the V2O5 nanoparticles to be wired up to a current collector through the underlying conducting graphene layers. As an anode material for lithium ion batteries, the composite exhibits a high reversible capacity of 1006 mAh g-1 at a current density of 0.5 A g-1 after 300 cycles. It also exhibits excellent rate performance with a discharge capacity of 500 mAh g-1 at the current density of 3.0 A g-1, which is superior to the performance of the vanadium-based materials reported previously. The electrochemical properties demonstrate that the sandwich-like V2O5/graphene mesoporous composite could be a promising candidate material for high-capacity anode in lithium ion batteries.
