以多孔阳极氧化铝为模板，采用溶胶-凝胶法成功制备了LiFePO4纳米管。透射电子显微镜和扫描电子显微镜表明合成的LiFePO4纳米管呈单分散且相互平行。选区电子衍射图、X射线衍射和X射线光电子能谱研究共同证明合成的LiFePO4纳米管为纯橄榄石结构。这种方法为在室温和环境条件下制造有序LiFePO4纳米管提供了一种潜在的方法，有望作为锂离子电池中的新型正极材料获得有前景的应用。
The LiFePO4 nanotubes were successfully fabricated by a sol-gel method with porous anodic aluminum oxide as the template. Transmission electron microscopy and scanning electron microscopy showed that the synthesized LiFePO4 nanotubes were monodispersed and parallel to one another. Selected area electron diffraction pattern, X-ray diffraction and X-ray photoelectron spectroscopy investigations jointly demonstrated that the synthesized LiFePO4 nanotubes were pure olivine structure. This approach offered a potentially way for fabricating ordered LiFePO4 nanotubes at room temperature and ambient conditions, which might be expected to find promising application as a new cathode material in lithium ion battery.
