| Abstract | A novel ultrathin W18O49@carbon nanowire web anode material for high performance lithium-ion batteries is synthesized via a facile one-step solvothermal method. A carbon layer is uniformly coated on ultrathin W18O49 nanowire bundles. The electrochemical properties are analyzed by cyclic voltammetry, galvanostatic charge/discharge cycling and electrochemical impedance. The W18O49@carbon nanowire web electrode exhibits a high lithium storage capacity of 889 mA h g−1 after 250 cycles at 200 mA g−1, which is the best cycling performance among the tungsten oxide anode materials used in lithium-ion batteries reported to date. The improved electrochemical performance can be ascribed to the incorporation of carbon and the unique ultrathin nanowire web architecture of the nanocomposite. |
