Abstract The LiFePO₄ nanowire arrays was successfully fabricated by a sol-gel method using anodic oxide aluminum (AAO) as the template. The field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) images showed the synthesized LiFePO₄ nanowire arrays were monodispersed and parallel to one another. The X-ray diffraction (XRD) and energy dispersive spectrometer (EDS) investigations jointly demonstrated a pure olivine structure of the synthesized LiFePO₄ nanowire arrays.The LiFePO₄ nanowire arrays also showed excellent electrochemical performance as cathode materials of lithium ion battery.Compared with nanoparticles prepared by the same condition,the nanowire arrays exhibited desirable rate performance (156.4 mAh/g at 0.1C and 106.9 mAh/g at 10C) and excellent cycle stability (99.1% after 100 cycles at 1C and 91.6% after 350 cycles at 10C).

Key words： lithium iron phosphate three-dimensional structured nanowire array anodic aluminum oxide template sol-gel method
