▎ 摘  要

WO3 nanorods/graphene nanocomposites (WO3/RGO) were prepared by the solvothermal treatment of tungsten hexachloride and graphene oxide in alcohol. The electrochemical performance of WO3/RGO as anode materials for lithium-ion batteries was investigated by galvanostatic charge-discharge tests, cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The discharge capacity of the composite at the first cycle was 761.4 mAh.g(-1), and about 635 mAh.g(-1) of reversible capacity remained after 100 cycles at a rate of 0.1C (1C=638 mA.g(-1)). The corresponding retention rate was 83.4%. The reversible capacity remained lager than 460 mAh.g(-1) at a rate of 5C. WO3/RGO exhibited excellent cycling stability and rate performance, and has potential in advanced lithium-ion batteries.
