the realization of the ideal MoS2/graphene structure in order to enhance electrochemical performance, mechanical robustness to ensure durability and stability remains elusive. The best structure should be a layered structure with MoS2 sandwiched between graphene sheets, which could not only effectively enhance the electron transfer between MoS2 sheets but also prevent aggregation of MoS2 sheets during the discharge/charge processes. In addition, a 3D porous structure could be formed by the interconnected graphene sheets, which could tolerate the volume change of MoS2 sheets and facilitate ion transport, giving rise to a greatly improved rate capability and cycling stability .
straightforward and cost-effective method to fabricate self-assembled, layer-by-layer, free-standing porous MG hydrogels from the mixed dispersion of MoS2 and LCGO. Heating at 70 °C (overnight at 1 atm), followed by a freeze-drying process resulted in an electroactive, porous, flexible film that was used directly as an electrode. The structure displayed excellent electrochemical properties as a lithium-ion battery anode: a high discharge capacity of 800 mAh g-1 at a current density of 100 mA g-1 ; and an excellent cycling stability with no capacity drop after 500 cycles at a current density of 400 mA g-1
