| Abstract: | In this paper,a novel yolk-shell Fe3O4@C composite had been synthesized via a simple wet chemical method.The morphologies,microstructures and chemical composition of Fe3 O4@C were characterized by transmission electron microscopy （TEM） and X-ray diffraction （XRD）.The Fe3 O4@C composite exhibited an excellent electrochemical performance as anode of lithium-ion battery （LIBs） with an excellent cyclic stability and high capacity,due to the unique yolk-shell structure. |
