以亚铁氰化钾，硫代硫酸铵等为反应物，CTAB作表面活性剂，采用水热法合成空心球Fe2O3。用X-射线粉末衍射，扫描电镜，高倍投射电镜对产物的组成，大小，形貌进行表征。结果表明，产物为纳米级空心球Fe2O3，并以此空心球为原料成功合成锂离子电池正极材料LiFePO4／C。

Fe2O3 hollow spheres were synthesized by hydrothermal method at an appropriate temperature for an appro-priate time using K4Fe(CN) 4. H2O and( NH4 )2S2O8 as source materials and cetyhrimethylammonium bromide (CTAB) as surfactant, the composite, size and morphology of the reaction products were characterized by X - ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM). The results showed that the re-action products were Fe2O3 hollow spheres with nanoscare. The LiFePO4/C was synthesized using Fe2O3 hollow spheres with nanoscare as the source material.
