[en] In this communication, Na3V2(PO4)2F3 (NVPF) powder with a NASICON-type structure is synthesized for the first time by spray-drying method. The effects of molar ratio of precursors, inlet temperature and heat treatment temperature on the powder purity and particle morphology were investigated. Structural and microstructural characterizations were carried out by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Best electrochemical properties, from specific capacities of 94 mAh .g-1 at C/15 to 80 mAh.g-1 at 1C in li-ion batteries, were obtained for powders dried at 180°C and fired at 600°C. These preliminary results show that spray-drying technique is suitable for obtaining complex powders with a very good homogeneity leading to very good electrochemical properties.
