•3D Fe3O4@GA was assembled from Fe(OH)3 colloid and graphene oxide for the first time.•The electrochemical properties of Fe3O4@GA anode materials for LIBs were investigated.•The hybrid composite was approved to be a promising anode material for LIBs.
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 m2 g−1) and large pore volume (0.3230 cm3 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.
