Abstract

Hydrated vanadium pentoxide (V₂O₅·0.86H ₂O) nanoribbons modified with reduced graphene oxide (RGO) are synthesized by a hydrothermal process. These ribbons are 30 nm thick, 200 nm to 1 μm wide and above 50 μm long. Binder-free films are prepared by using these ribbons and annealed at 300 C in nitrogen as the cathode for rechargeable lithium cells. The intertwining network of this free-standing VO_x/RGO film provides efficient conduction pathways for electrons and short diffusion distances for Li ions. The electrochemical tests exhibit that this cathode film delivers a high reversible specific capacity (160 mAh g^-1) and good cycling stability (133 mAh g^-1 after 200 cycles) in the voltage range between 2.0 and 3.5 V.
