摘　　要：通过循环伏安法、X射线衍射法、电子探针微区分析法、原子吸收光谱法等物理化学分析方法指出,经过苯胺改性后的氧基氯化铁(FeOCl)具有一定的电化学可逆性,可用作为锂二次电池的阴极活性物质.Modified FeOCl, which was chemically prepared by Cl ion exchanging in agueous solution of aniline, exhibits a good Charge and discharge characteristics in lithium battery, giving moderate coulombic efficiency and higher discharge voltage. With the results of atomic absorption analysis, EPMA, XRD, and cycling profile, it is confirmed that the modified FeOCl has a higher reversible electrochemical process for Li+ ion, Li+ ion can be intercalated and deintercalated elec-trochemically in its layers.
