Abstract

It was found that the a-Fe2O3nanoparticles were well dispersed and embedded into the 3D porous structure of graphene aerogel (GA). Compared with that (SBET= 82 m2g−1) of pristine a-Fe2O3, the resulting composites exhibited much higher specific surface area (SBET= 261 m2g−1). The composites used as anode materials for lithium ion batteries maintained a high reversible capacity of 745 mAh g−1at a current density of 100 mA g−1or more than 240 mAh g−1at a current density of 2000 mA g−1after 100 cycles, and exhibited superior stable electrochemical cycling performance and excellent rate capability. The superior electrochemical performances were attributed to the synergistic effects of the unique 3D porous structure of the composites with high contents of well dispersed a-Fe2O3.
