Abstract Lithium‐sulfur batteries (LiSBs) with high energy density still face challenges on sluggish conversion kinetics, severe shuttle effects of lithium polysulfides (LiPSs), and low blocking feature ordinary separators to LiPSs. To tackle these, a novel double‐layer strategy functionalize is proposed, which consists Co atomically dispersed CoN 4 decorated Ketjen black (Co/CoN @KB) layer an ultrathin 2D Ti 3 C 2 T x MXene layer. The theoretical calculations experimental results jointly demonstrate metallic sites provide efficient adsorption catalytic capability for long‐chain LiPSs, while active facilitate the absorption short‐chain LiPSs promote Li S. stacking serves as microscopic barrier further physically block chemically anchor leaked from pores gaps Co/CoN @KB layer, thus preserving within anchoring‐conversion reaction interfaces balance accumulation “dead S” Consequently, ultralight loading @KB‐MXene, LiSBs exhibit amazing electrochemical performance even under sulfur lean electrolyte, outperforming lithium‐selenium (LiSeBs) can also be achieved. This work exploits universal effective functionalized separator regulate equilibrium adsorption‐catalytic interface, enabling high‐energy long‐cycle LiSBs/LiSeBs.

The severe shuttle effect of polysulfides (LiPSs) and the slow liquid–solid phase conversion are main obstacles hindering practical application lithium–sulfur (Li–S) batteries. Separator modification with a high-activity catalyst can boost LiPSs suppress their effect. In this work, multi-heterostructured MXene/NiS2/Co3S4 rich S-vacancies was constructed facilely hydrothermal high-temperature annealing strategy for separator modification. MXene sheet not only provides physical barrier but also ensures high conductivity adsorption capacity catalyst; dual active centers NiS2 Co3S4 catalyze conversion. addition, vacancies heterostructures modulate electronic structure catalyst, improve its intrinsic activity, reduce reaction barrier, thus facilitating ion/electron transport inhibiting Benefiting from these advantages, Li–S battery modified exhibits exciting discharge capacities (1495.4 mAh g–1 at 0.1C 549.0 6C) an excellent ultra-long cycle life (average decay rate 0.026% 2000 cycles 2C); sulfur loading 10.0 mg cm–2, operates nearly 80 0.2C, giving retention 75.76%.

Lithium–sulfur (Li-S) batteries are recognized as a promising alternative in the energy storage domain due to their high theoretical density, environmental friendliness, and cost-effectiveness. However, challenges such polysulfide dissolution, low conductivity of sulfur, limited cycling stability hinder widespread application. To address these issues, incorporation heterostructured metallic substrates into Li-S has emerged pivotal strategy, enhancing electrochemical performance by facilitating better adsorption catalysis. This review delineates modifications made cathode separator through heterostructures. We categorize heterostructures three classifications: single metals metal compounds, MXene materials paired with formed entirely compounds. Each category is systematically examined for its contributions behavior efficiency batteries. The evaluated both contexts, revealing significant improvements lithium-ion retention. Our findings suggest that strategic design can not only mitigate inherent limitations but also pave way development high-performance systems.
