摘要
为深入了解BaFeO4在干燥环境中的稳定性及分解机理,采用恒流放电、X射线光电子能谱 (XPS)、X射线衍射(XRD)、红外吸收光谱(IR)等测试手段研究了BaFeO4在不同处理方法后的放电性能和结构性质。恒流放电结果显示,BaFeO4的放电性能随着其放置时间的延长而不断降低;XPS结果证实 BaFeO4样品在干燥环境中放置时会逐渐分解为低价态铁盐,并讨论了其可能分解机理。
The instability and decomposition mechanism of BaFeO4 in dry environment were studied by means of constant current discharge, XPS, XRD and IR spectra. With the increase of keeping time in dry environment, BaFeO4 decomposes into Fe salts with lower valence state slowly, and results in the decrease of discharge performance. The possible decomposed mechanism of BaFeO4 was suggested according to the XRD and IR results.
