摘要:
采用溶胶凝胶法在氧化铝模板中成功的制备了LiFePO4一维纳 米管阵列. 扫描电子显微镜和透射电子显微镜表征结果表明所制备 的LiFePO4纳米管具有单分散性,互相平行,高度有序。综合选区电 子衍射、X射线衍射以及X光线能谱表征结果,所制备的LiFePO4纳 米管为单一的橄榄石型结构. 这种在室温和温和条件下合成的一 维LiFePO4纳米管,可以做为新型的锂离子电池正极材料.

Fabrication and Characterization of LiFePO4 Nanotubes by a Sol-gel-AAO Template Process

Abstract:
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 synthe- sized 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.
