▎ 摘　　要

A free-standing MoS2-graphene flexible film (MoS2/GN-F) is designed and prepared by a facile vacuum filtration method without using any templates. SEM and TEM images show that the MoS2/GN flower-like particles are self-assembled by MoS2 nanoflakes and graphene nanosheets. Electrochemical performances of the MoS2/GN-F film as anode active material in Lithium-ion batteries (LIBs) are investigated in both MoS2/GN//Li half-cells and MoS2/GN//LiCoO2 full-cells. The MoS2/GN-F sample maintains high reversible discharge capacities of 700.3 mAh g(-1) after 100 cycles at 400 mA g(-1) in MoS2/GN//Li half-cells. The assembled MoS2/GN-F//LiCoO2 full-cell delivers high initial discharge capacities of 1149.1 mAh g(-1). The excellent lithium storage performances of the obtained MoS2/GN-F film can be mainly attributed to the designed novel structure of the composite. The cross-linked graphene nanosheets, the anchoring MoS2 nanoflakes, and the synergistic effects between them make the composite good conductivity, enough buffering space for the volume change, and shortened ionic transport length. This work clearly demonstrates that the MoS2/GN-F film is a promising alternative material for anode in the LIB applications.
