The LiFeSO4F was successfully synthesized from the reactions of FeSO4?xH2O (x=1, 4, 7) with LiF in tetraethylene glycol media through a facile low temperature method. The structures and microscopic features of the products were characterized by XRD, SEM and TEM. TGA result shows the good thermal stability of the as-prepared LiFeSO4F. No diffraction peaks of the FeSO4 are observed in the as-prepared products with the starting material of either FeSO4?4H2O or FeSO4?7H2O, which should be ascribed to delaying the release of H2O from the hydrated compounds. Cyclic voltammetry (CV) curves and electrochemical impedance spectroscopy (EIS) results prove that the LiFeSO4F/graphene composite exhibit less electrochemical polarization and smaller impedance than those of pure LiFeSO4F, in which the graphene serves as the electronic conductivity support to enhance the lithium storage properties. The LiFeSO4F/graphene composite shows a high specific capacity, good rate capability and cycling stability compared with the pure LiFeSO4F.
