ChemInform Abstract: Structure and Stability of Sodium Intercalated Phases in Olivine FePO4.

Abstract Two new Na x FePO 4 (x = 0.7, 1) phases with olivine‐based structures are electrochemically synthesized using a mixture of FePO 4 and carbon black as positive electrode, Na as negative electrode, and NaClO 4 solution as electrolyte.
