Abstract

WO₃ nanowires/graphene nanocomposite was synthesized via a facile hydrothermal method and evaluated as an anode for lithium ion battery. The nanocomposite is composed of WO₃ nanowires uniformly distributed on graphene matrix. The electrochemical properties were analyzed using cyclic voltammetry and galvanostatic charge/discharge cycling. The nanocomposite electrode exhibited a reversible lithium storage capacity of 656 mAh g ^-1 after 100 cycles at 100 mA g^-1 and an enhanced cyclability compared with the bare WO₃ nanowires electrode. The improved electrochemical performance could be ascribed to the incorporation of graphene and the unique 3D architecture of the nanocomposite.
