Abstract With abundant electroactive sites and rapid ion diffusion paths, ultrathin dichalcogenides such as MoS 2 demonstrate enormous potential anodes for sodium/potassium‐ion batteries (SIBs/PIBs). However, ultrahigh‐aspect‐ratio nanosheets are very easy to aggregate re‐stack, drastically weakening their intrinsic merits. Here a sustainable dichalcogenide anode is designed via crumpling carbon‐pillared atomic‐thin with CNTs into an elastic ball structure (C‐p‐MoS /CNTs). In this architecture, the glucose‐derived carbon pillars broadens interlayer spacing, ensuring fast Na + /K diffusion; act 3D scaffolds impede re‐stacking of while providing high‐speed pathways electrons; integration flexible sheets high‐toughness further endows balls great elasticity release cycling stress. Consequently, C‐p‐MoS /CNTs material delivers high reversible capacities, outstanding stability, superior rate performance both SIBs PIBs.
