Preparation of Nanoplatelet-Like MoS2/rGO Composite as High-Performance Anode Material for Lithium-Ion Batteries

In this paper, we report a facile strategy to design and prepare reduced graphene oxide (rGO) supported MoS2 nanoplatelet (MoS2/rGO) via a solvothermal co-assembly process. It is found that in the as-obtained MoS2/rGO nanocomposite, MoS2 possesses unique platelet structure and rGO is exfoliated due to the in situ growth of MoS2 nanoplatelet, leading to a large specific surface area, facilitating rapid diffusion of lithium ions. The nanocomposite is used as a promising anode material for lithium-ion batteries and displays a high initial charge capacity (1382 mAh g(-1)), excellent rate capability and cycling stability. The remarkable lithium storage performance of MoS2/rGO nanocomposite is mainly ascribed to the inherent nanostructure of the MoS2, and the synergistic effect between rGO nanosheets and MoS2 nanoplatelets.
