Fe_(3–x)O_4 raspberry shaped nanostructures/graphene nanocomposites were synthesized by a one-step polyol-solvothermal method to be tested as electrode materials for Li-ion battery(LIB). Indeed, Fe_(3–x)O_4 raspberry shaped nanostructures consist of original oriented aggregates of Fe_(3–x)O_4 magnetite nanocrystals, ensuring a low oxidation state of magnetite and a hollow and porous structure, which has been easily combined with graphene sheets. The resulting nanocomposite powder displays a very homogeneous spatial distribution of Fe_(3–x)O_4 nanostructures at the surface of the graphene sheets. These original nanostructures and their strong interaction with the graphene sheets resulted in very small capacity fading upon Li+ion intercalation. Reversible capacity, as high as 660 m Ah/g, makes this material promising for anode in Li-ion batteries application.
Fe 3-x O 4 raspberry shaped nanostructures / graphene nanocomposites were synthesized by a one-step polyol-solvothermal method to be tested as electrode materials for Li-ion battery (LIB). Indeed, Fe_ (3-x) O_4 raspberry shaped nanostructures consist of original oriented aggregates of Fe_ (3-x) O_4 magnetite nanocrystals, ensuring a low oxidation state of magnetite and a hollow and porous structure, which has been easily combined with graphene sheets. The resulting nanocomposite powder displays a very homogeneous spatial distribution of Fe_ (3-x) O_4 nanostructures at the strong interaction with the graphene sheets resulted in very small capacity fading on Li + ion intercalation.
