摘要
Carbon composites of open-framework iron fluoride (FeF3 center dot 0.33H(2)O/C) was investigated as a new cathode material for calcium ion batteries for the first time. FeF3 center dot 0.33H(2)O/C delivers a relatively large capacity of ca. 110mAhg(-1). Its reversible capacity was greatly improved over non-composite FeF3 center dot 0.33H(2)O. During the first discharge and discharge-charge, insertion/extraction of Ca2+ into/from FeF3 center dot 0.33H(2)O/C were confirmed by an ex-situ X-ray photoelectron spectroscopy (XPS) and energy dispersive X-ray spectroscopy (EDX) analysis. From the ex-situ analysis results, it was confirmed that Ca2+ was inserted and extracted with redox of Fe.
