Résumé en anglais

Sodium rich iron hexacyanoferrates were prepared by coprecipitation, hydrothermal route, and under reflux, with or without dehydration. They were obtained with different structures described in cubic, orthorhombic or rhombohedral symmetry, with variable compositions in sodium, water and cationic vacancies, and with a variety of morphologies. This series of sodium rich Prussian Blue Analogs allowed to address the relationship between synthesis conditions, composition, structure, morphology and electrochemical properties in Na-ion batteries. A new orthorhombic phase with the Na 1.8 Fe 2 (CN) 6 •0.7H 2 O composition synthesized by an hydrothermal route at 140°C is reported for the first time, whereas a phase of Na 2 Fe 2 (CN) 6 •2H 2 O composition obtained under reflux, previously described with a monoclinic structure, shows in fact a rhombohedral structure.< Réduire
