Abstract

Hierarchical structures of Li1+xV3O8 nanorods growing on electrospun fibers have been successfully synthesized by electrospinning and calcinations. Field-emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction and Raman spectra are applied to characterize the products. The formation mechanism of the hierarchical structures is investigated, showing that the morphology of the hierarchical structures is mainly determined by calcined conditions, such as temperature and time of calcination. Electrochemical properties of the Li1+xV3O8 hierarchical structures are investigated by cyclic voltammetry and charge-discharge experiments. The results demonstrate that the Li1+xV3O8 hierarchical structures exhibited a high discharge capacity (313 mAhg-1) and excellent cycling stability.
