In this work, a facile, one-pot route has been applied to synthesize nanohybrids based on mixed oxide Ni Fe2O4 and reduced graphene oxide(r GO). The hybrid is constructed by nanosized Ni Fe2O4 crystals confined by fewlayered r GO sheets. The formation mechanism and microstructure of the hybrids have been clarified by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy.Electrochemical tests show that the performance of Ni Fe2O4 can be considerably improved by r GO incorporation. The performance improvement can be attributed to the two-dimensional conductive channels and the unique hybrid structure r GO constructed. The easy synthesis and good electrochemical performance of Ni Fe2O4/r GO hybrid make it a promising anode material for Li-ion batteries.
