摘要
层状化合物FeOCl作为锂一次电池阴极活性物质时表现为了电子放电,平均放电压为2.2v,放电平台长,放电的最终产物是α—Fe,放电容量比单电子放电的Li/MnO_2电池大一倍以上,是一种有前途的新型电源材料。经过改性处理后的氧基氯化铁,其结构稳定性增大,可望作为锂二次电池的阴极活性物质。
Iron oxychloride(FeOCl)was a layered compound having a b-axis prefered orientation with an in-terlayer distance of 7. 9 A- During the discharge,lithium ion could be intercalated into the van der wall gaps. Three electrons were consumed during the discharge reaction. α-Fe was formed during the discharge,that was confirmed by X-ray diffraction analysis of the discharge products.
