The LiV3O8 nanowires are fabricated by using sol-gel process with porous anodic aluminum oxide (AAO) as the template. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) characterizations show that the synthesized LiV3O8 nanowires are monodispersed and paralleled to one another. Selected area electron diffraction (SAED) pattern, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) investigations jointly demonstrate that the synthesized nanowires are most consisted of monoclinic phase LiV3O8. Since the LiV3O8 nanowires can be mass-produced by using this method, it is expected to find promising application as a new cathode material in lithium ion battery.
