摘要：

Monodispersed LiFePO4 [001] nanorods have been successfully synthesized via a conventional hydrothermal route with Li2SO4, FeSO4 and KH2PO4 as precursors. Subsequently, in virtue of the good monodispersibility LiFePO4@C core-shell [001] nanorods are facilely prepared by employing a carbon coating process on the obtained monodispersed LiFePO4 [001] nanorods. On the basis of the experimental results, a possible formation mechanism of the monodispersed LiFePO4 [001] nanorods has been proposed. Due to the full carbon coating, size reducing in [010] and the perfect olivine crystal lattice, the LiFePO4@C core-shell [001] nanorods exhibit excellent rate capacity and stable cycle performance.
