A novel facile strategy was developed to prepare the Fe3O4@graphene aerogel (Fe3O4@GA) composites. Fe3O4 nanoparticles were uniformly dispersed into the 3D network of graphene aerogel and the resultant hybrid composites contained meso-and macro-scale pores with high specific surface area (276.9 m(2) g(-1)) and large pore volume (0.3230 cm(3) g(-1)). The electrochemical performance revealed that the Fe3O4@GA anode exhibited high reversible capacity (941.5 mAh g(-1) at a current density of 100 mA g(-1)), stable cycling performance, and excellent rate capability.
