The lithiated vanadium oxides half opened- nanotubes are synthesized by using solvothermal reaction with octadecylamine oxide as the template.Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) characterizations show that the lithiated vanadium oxides nanotubes are half opened and agglomerate.X-ray diffraction (XRD) investigation demonstrates that the synthesized half opened-nanotubes are most consisted of monoclinic phase LiV3O8.Cyclic voltammetry (CV) test indicates that some redox processes are hindered,which is propitious to improve electrochemical performance of LiV3O8 cathode material.
