Three kinds of FeOOH derivatives were prepared from FeOCl using the ion exchange reaction of Cl- ion in FeOCl with OH- and CH3O-. The reaction products were identified as γ-FeOOH, the amorphous FeOOH including aniline, and FeOOCH3. The amorphous FeOOH including aniline showed a much better performance as cathode of the rechargeable lithium battery than that of γ-FeOOH and FeOOCH3. The discharge behavior of γ-FeOOH was similar to that of FeOOCH3. From these results, it was found that the aniline interacted with FeOOH matrix played an important role for the high discharge potential (more than 3.0 V versus Li/Li+) and the high discharge capacity (more than 200 mA h g-1) of the amorphous FeOOH including aniline.
