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 The sluggish redox kinetics of lithium polysulfides (LiPSs) and their shuttle behavior are regarded as the key issues to commercial application lithium–sulfur (Li–S) batteries. Here, a novel LiPSs immobilizer catalytic promoter is proposed by introducing oxygen‐vacancy‐rich cerium dioxide (CeO 2– X ) nanocrystalline embedded in N‐doped carbon skeleton @NC) investigated modified separator Li–S Density functional theory calculations, UV– vis diffusion reflection spectra, X‐ray photoelectron spectroscopy indicate that oxygen vacancies can tailor intrinsic electron band structure CeO nanocrystalline, which able improve ion conductivity. This leads enhanced adsorption realize targeted acceleration conversion for LiPSs. In return, sulfur cathodes based on @NC demonstrate both stable long‐lifespan cyclability (over 1000 cycles at 4 C) superior rate performance (up C). Additionally, high areal capacity 5.61 mAh cm −2 loading 7.09 mg also achieved. work underscores imperative incorporating defect heterostructure engineering enhance fast charge–discharge capability stability batteries, offering new approach potential applications.
