▎ 摘　　要

In this work, a facile, one-pot route has been applied to synthesize nanohybrids based on mixed oxide NiFe2O4 and reduced graphene oxide (rGO). The hybrid is constructed by nanosized NiFe2O4 crystals confined by few-layered rGO 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 NiFe2O4 can be considerably improved by rGO incorporation. The performance improvement can be attributed to the two-dimensional conductive channels and the unique hybrid structure rGO constructed. The easy synthesis and good electrochemical performance of NiFe2O4/rGO hybrid make it a promising anode material for Li-ion batteries.
