Abstract


  • Particular N, S co-doped graphene/Fe3O4 hybrids have been successfully synthesized by the

    combination of a simple hydrothermal process and a subsequent carbonization heat treatment. The

    nanostructures exhibit a unique composite architecture, with uniformly dispersed Fe3O4 nanoparticles

    and N, S co-doped graphene encapsulant. The particular porous characteristics with many meso/micro

    holes/pores, the highly conductive N, S co-doped graphene, as well as the encapsulating N, S co-doped

    graphene with the high-level nitrogen and sulfur doping, lead to excellent electrochemical performance

    of the electrode. The N-S-G/Fe3O4 composite electrode exhibits a high initial reversible capacity of

    1362.2 mAhg−1, a high reversible specific capacity of 1055.20 mAhg−1 after 100 cycles, and excellent

    cycling stability and rate capability, with specific capacity of 556.69 mAhg−1 when cycled at the current

    density of 1000 mAg−1, indicating that the N-S-G/Fe3O4 composite is a promising anode candidate for

    Li-ion batteries.
