Abstract

A highly ordered LiNi_0.5Mn_0.5O₂ nanowire array was prepared using a porous anodic aluminium oxide (AAO) template from a sol–gel solution containing Li(OAc), Ni(OAc)₂ and Mn(OAc)₂. Electron microscopy results show that LiNi_0.5Mn_0.5O₂ nanowires of uniform length and diameter are obtained, and that the length and diameter of the LiNi_0.5Mn_0.5O₂ nanowires are dependent upon the pore diameter and the thickness of the applied AAO template. X-Ray diffraction and electron diffraction investigations demonstrate that the LiNi_0.5Mn_0.5O₂ nanowires have a layered structure of LiNi_0.5Mn_0.5O₂. X-ray photoelectron spectroscopy indicates that a nearly stoichiometric layered LiNi_0.5Mn_0.5O₂ material has been obtained.
