Abstract

Abstract : Zinc silicate (Zn2 SiO4 ) nanorods with diameters of 90–100 nm and lengths of up to 600–700 nm have been successfully prepared by a simple hydrothermal route without the assistance of any templates or surfactants. The characterisations of the products were carried out by X‐ray diffraction (XRD), field‐emission scanning electron microscopy and transmission electron microscopy technology. On the basis of XRD and scanning electron microscopy analyses of the products at different reaction time periods, an Ostwald ripening mechanism is proposed to elucidate the formation mechanism of the nanorod structure. The electrochemical performance of the as‐prepared Zn2 SiO4 nanorods was investigated by a galvanostatic charge–discharge method. The results have shown that the Zn2 SiO4 nanorods exhibited a higher discharge capacity and better cyclability than the Zn2 SiO4 bulk materials.
