A new desodiated derivative compound, Na_0.89Fe_1.8(SO₄)₃, was prepared by the chemical oxidation of alluaudite Na_2.4Fe_1.8(SO₄)₃ phase using NOBF₄ as oxidant. The structure and valency of Fe were characterized by X-ray diffraction (XRD) and ⁵⁷Fe Mössbauer spectroscopy. Intercalation behavior of lithium ions in the structure of Na_0.89Fe_1.8(SO₄)₃ was gauged by electrochemical analyses and ex-situ X-ray diffraction. A high capacity of 110 mAh g^{- 1} at 0.1 C was obtained with a good rate kinetics within a range of 0.1-10 C(1 C = 118 mAh g^{- 1}) involving a high Fe^{3 +}/Fe^{2 +} redox potential of 3.75 V (vs. Li/Li⁺). These results confirmed that the Na_{2.4- δ}Fe_1.8(SO₄)₃ framework was stable even after oxidation and forms a new competitive cathode for the reversible intercalation of lithium ions.
