Abstract: A flower-like MoS2-graphene nanosheet-CNT (MoS2-GNS-CNT) nanocomposite is successfully prepared by a facile hydrothermal process for fast lithium storage. The introduction of a graphene backbone and CNTs prevent the growth of MoS2, resulting in the formation of few layered nano-MoS2 (about 5-10 nm). The CNTs are intimately embedded in the composites to form highly conductive 3D networks, which serve as a highly conductive substrate leading to the high-rate performance. In addition, CNTs in the unique hybrid nanostructure prevent the restacking of GNS. The MoS2-GNS-CNT composite exhibits superior rate capability (300 mA h g(-1) at 20 A g(-1)) and ultralong cyclability (728 mA h g(-1) at 5 A g(-1) after 1000 cycles). We believe that our strategy could be broadly applicable for the preparation of other transition metal dichalcogenide (TMD) materials with great promise for various applications.
