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 structure 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.

具有精心设计的多孔结构的硫化钼（MoS ₂）由于其高理论容量和丰富的资源而具有成为钠离子电池电极材料的潜力，但其固有的低电导率和稳定性受到阻碍。在此，的MoS ₂的三维大孔的泡沫结构和高导电性的SiO通过获得₂模板和与碳纸（3D F-集成的MoS ₂ / CP）。它在高倍率（2000 mA h g ^-1，0.4-3 V）和循环稳定性（1000 次循环）下表现出优异的比容量（225 mA h g ^-1)，在钠离子电池中具有低衰减率（每个循环 0.033%）。优异的电化学性能可能源于其独特的集成结构：3D MoS ₂大孔提供高表面积和丰富的传输通道，同时碳纸增强了MoS ₂的导电性并避免了添加粘合剂带来的不必要的副反应。
