▎ 摘  要

Here graphene coating magnetite/N-doped carbon hybrid materials (G@Fe3O4/NC) have been synthesized. Structural characterizations revealed that Fe3O4/N-doped carbon was wrapped tightly and uniformly by graphene nanosheets via pi-pi interactions, which preventing the volume expansion of the material during the charge/discharge processes. G@Fe3O4/NC hybrid composites exhibited a large discharge specific capacity of 958 mAh g(-1) after 65 cycles at a current density of 200 mA g(-1). (C) 2018 Elsevier B.V. All rights reserved.
