Abstract
Several techniques including electrochemical measurements, in situ X-ray diffraction, Mössbauer spectroscopy, and X-ray absorption spectroscopy (XAS) were used to study the lithium-insertion/deinsertion properties of five hydrated iron phosphates. Crystalline phosphosiderite undergoes a complete two-phase lithium-insertion mechanism, giving rise to isosbestic points on the superposition of normalized XAS spectra. Lithium insertion into crystalline strengite reveals a two-phase region followed by a single-phase one. Amorphous compositions are described as disordered solid mixtures of clusters: Such a description accounts for both the presence of isosbestic points on the superposition of XAS spectra recorded at different stages of Li insertion and for the sloping open-circuit potential.
