Here, we develop amorphous carbon coated Na7Fe7(PO4)6F3, prepared by combining hydrothermal and solid state reaction methods, as an insertion electrode for sodium-ion batteries applications. Na7Fe7(PO4)6F3 particles are surrounded by a thin layer (∼1.5–2 nm) of amorphous carbon. The Na7Fe7(PO4)6F3/C composite cathode undergoes reversible sodium intercalation/de-intercalation with an average operational potential of ∼3.0 V (vs Na+/Na). This cathode has a capacity of 65 mA h g−1 at 100 mA g−1 current after 60 cycles and features twice higher capacity than that of an uncoated Na7Fe7(PO4)6F3 sample. Therefore, the carbon-coated Na7Fe7(PO4)6F3 composite presents feasible sodium intercalation/de-intercalation capacity, offering possibilities for developing a low cost, high performance sodium-ion battery positive electrode.
