Kurzfassung:
A novel composite, MoS 2 ‐coated three‐dimensional graphene network (3DGN), referred to as MoS 2 /3DGN, is synthesized by a facile CVD method. The 3DGN, composed of interconnected graphene sheets, not only serves as template for the deposition of MoS 2 , but also provides good electrical contact between the current collector and deposited MoS 2 . As a proof of concept, the MoS 2 /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 MoS 2 /3DGN composite also shows excellent high‐current‐density performance, e.g., depicts a 10 th ‐cycle capacity of 466 mAh g −1 at a high current density of 4 A g −1 .
