▎ 摘  要

This letter reports on the synthesis of Fe3O4@ graphene composites (FGC) and their applications as anode materials in lithium-ion batteries (LIBs). As an anode material for LIBs, the FGC exhibited discharge and charge capacities of 1354 and 953 mAh g (1) in the initial cycle at 200 mA g (1), respectively. And more impressively, 639 mAh g (1) was remained after a twenty-five fold increase in current density to 5 A g (1). Especially, the capacity steadily maintained at 788 mAh g (1) even after 500 charge-discharge cycles at 1 A g (1). Such a high capacity and excellent cycling stability can be attributed to the strongly coupled interactions between graphene sheets and Fe3O4 NPs. (C) 2017 Elsevier B.V. All rights reserved.
