摘要: 本文讨论了FeOCl及在不同条件下改性的FeOCl的物理化学和电化学性质。XRD、IR、EPMA等测试结果表明,低温改性处理时,苯胺嵌入FeOCl层间,并不与FeOCl发生任何反应;改性温度较高时,苯胺与FeOCl发生了置换反应,析出HCl,嵌入FeOCl中的苯胺将相互结合为苯胺齐聚物。化学改性处理后的FeOCl的充放电可逆性将有明显提高。

Abstract: Modified FeOCI, which was chemically prepared by Cl ion exchanging in aqueous aniline solution, shows a good discharge and charge 'characteristics.In the present study, the differences between FeOCIand modified FeOCIare reported in the bahaviour of XRD, EPMAand IRspectra.The comparision of spectra for the oligomer of polyaniline and the modified FeOCIconfirms very similar structure.XRDresults show that the modified FeOCIdisplays a reversible structure changes in charge and discharge.The charge-discharge curves gave a higher discharge voltage.

Key words: FeOC1, Modified FeOCl, Layer compound, Lithium battery
