Molybdenum sulfide (MoS2) with well-designed porous structure has the potential to be great electrode materials in sodium-ion batteries due to its high theoretical capacity and abundant resource,however,hindered by its intrinsic low conductivity and stability.Herein,MoS2 with 3D macroporous foam struc-ture and high conductivity was obtained through SiO2 templates and integrated with carbon paper (3D F-MoS2/CP).It has showed superior specific capacity (225 mA h g-1,0.4-3 V) and cycling stability (1000 cycles) at high rate (2000 mA g-1),with a low decay rate (0.033％ per cycle) in sodium-ion batteries.The excellent electrochemical performance may originate from its unique integrated structure 3D MoS2 macropores providing high surface area and abundant transfer channels while carbon paper enhancing the conductivity of MoS2 and avoiding unnecessary side reactions brought by binder addition.
