Preparation of MoS 2 ‐Coated Three‐Dimensional Graphene Networks for High‐Performance Anode Material in Lithium‐Ion Batteries

A novel composite, MoS2 -coated three-dimensional graphene network (3DGN), referred to as MoS2 /3DGN, is synthesized by a facile CVD method. The 3DGN, composed of interconnected graphene sheets, not only serves as template for the deposition of MoS2 , but also provides good electrical contact between the current collector and deposited MoS2 . As a proof of concept, the MoS2 /3DGN composite, used as an anode material for lithium-ion batteries, shows excellent electrochemical performance, which exhibits reversible capacities of 877 and 665 mAh g(-1) during the 50(th) cycle at current densities of 100 and 500 mA g(-1) , respectively, indicating its good cycling performance. Furthermore, the MoS2 /3DGN composite…
