dc.description.abstract | A novel iron fluorophosphite, NaFe3(HPO3)2((H,F)PO2OH)6, was synthesized by a dry low-temperature synthesis route. The phase was shown to be electrochemically active for reversible insertion of Na+ ions, with an average discharge voltage of 2.5 V and an experimental capacity at low rates of up to 90 mAhg−1. Simple synthesis, low-cost materials, excellent capacity retention, and efficiency suggest this class of material is competitive with similar oxyanion-based compounds as a cathode material for Na batteries. The characterization of physical properties by means of magnetization, specific heat, and electron spin resonance measurements confirms the presence of two magnetically nonequivalent Fe3+ sites. The compound orders magnetically at TC ≈ 9.4 K into a state with spontaneous magnetization. | |
