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.

ABSTRACT Lithium–sulfur (Li–S) batteries are proposed as next‐generation energy storage devices due to their high theoretical capacity and specific energy. However, the actual utilization is greatly limited by poor reactivity of sulfur reduction reaction (SRR), which motivates us develop corresponding high‐efficient catalysts. Inspired application MXene single‐atom catalysts (SACs) in improving SRR, a virtual screening on MXene‐supported SACs from imp2d database carried out. Finally, six kinds top identified for most them can be considered variants previous representative SRR catalysts, reflects rationality our screening. Meanwhile, stability metrics calculated density functional theory (DFT) show obvious trends depending type adatom/MXene. For critical intermediate binding that tune activity, further electronic structure analysis reveals so‐called 10‐electron count rule, whose decisive role also reflected Shapley value machine learning (ML).
