Hydrothermal Synthesis and Electrochemical Property of Self-Assembly K10[H2W12O42]⋅10H2O Nanorod

Using KOH and WO3 as raw materials, K-10[H2W12O42]center dot 10H(2)O nanorod was successfully synthesized via controlling the pH value and the K/W mole ratio of hydrothermal system. The structure and morphology of the samples were characterized by XRD, SEM, TEM, HRTEM and selected area electron diffraction (SAED). The size of K-10[H2W12O42]center dot 10H(2)O nanorod was about 300 nm in width and 3-10 mu m in length. The nanorod consisted of self-assembly nanowires with about 10nm in width. Moreover, the electrochemical performance of K-10[H2W12O42]center dot 10H(2)O as anode material was investigated, indicating that the as-prepared sample electrode possessed a certain ability of lithium ion insertion/extraction, and exhibited a high initial discharge capacity of 310 mAh g(-1).
