The purpose of this work is the search and development of new-based composite materials as negative electrode for rechargeable lithium ion batteries. In order to understand the relationship structure-texture-properties allowing to optimize this material, several complementary techniques of characterization (X-ray diffraction, scanning electron microscopy, differential scanning calorimetric and thermo gravimetric analysis, 119Sn Mössbauer spectroscopy, X-ray absorption) were coupled to study global and local order in the composite material. Accurate analysis of the lithium reaction mechanism for the composite material [Sn-BPO4], realized by coupling electrochemical and spectroscopic methods, made it possible to understand the reversibility o...
