%X Lithium vanadium oxide nanotubes as cathode materials for rechargeable lithium batteries were prepared via a sol-gel reaction followed by hydrothermal treatment, in which V2O5 and LiOH ¤H2O were used as raw materials and C16H33NH2 as structure-directing template. Structure and morphology of the nanotubes were investigated by SEM, TEM, XRD, FT-IR and XPS.Meantime, electrochemical behavior of the materials was researched by cyclic voltammetry. The results show that the inner and the outer diameters of the obtained nanotubes are of about 30nm and 70nm with length between 1|  to 3| , respectively. It is also confirmed by XPS that the elements of the products are made up of various chemical states. The electrochemical performance indicates that the obtained nanotubes as cathode materials for rechargeable lithium batteries have good lithium-ion insertion/deinsertion reversibility.
