摘要：
Reduced graphene oxide (rGO) modified vanadium teroxide (V2O3) is synthesized by a solvothermal process followed with calcination treatment in a reducing atmosphere. The as-prepared hybrid materials were quite uniform and V2O3 distributed homogeneously in the hybrid composite. The influence of annealing atmospheres to the electrochemical performance of the electrode material was also studied. As an anode material for lithium ion batteries, the V2O3-rGO composite exhibited higher capacity and better cyclic stability. (C) 2014 Elsevier B.V. All rights reserved.
