Crystal structure and electrochemical properties of phosphosulphate NaFe2PO4(SO4)2

NASICON-type NaFe2(PO4)(SO4)2 (NFPS) electrode material is successfully synthesized via a rheological route. DSC/TG analysis shows that it is thermally stable up to 760 °C. A carbon composite NFPS/C was obtained using ball milling. NFPS and NFPS/C were investigated as cathode and anode materials for sodium-ion batteries. Analysis of migration paths was performed by the Voronoi-Dirichlet partition technique to determine all possible Na+ ion migration paths. The diffusion coefficient, estimated by GITT, is in the 10-12-10-13 cm2∙s-1 range, which corresponds to the fast Na+ ion migration in the structure. According to calculations, NFPS is a wide band gap material, which indicates its poor electrical conductivity.
