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 intrinsically sluggish sulfur reduction reaction kinetics and serious shuttle effect of soluble lithium polysulfides (LiPSs) severely impede the practical commercialization lithium‐sulfur (Li‐S) batteries. Herein, self‐supported tungsten nitride carbide heterostructures with vanadium doping that are directly grown on carbon cloth substrate (CC@V‐W 2 N/WC 1‐ x ) creatively designed for Li‐S batteries, which can tandemly catalyze liquid–liquid conversion liquid–solid polysulfide intermediate free any interference from polymer binders conductive additives. Noteworthy, rich heterointerfaces beneficial rapid charge transfer, strong chemical adsorption toward LiPSs, massive exposed catalytically active sites, remarkable catalytic activities. Consequently, batteries assembled CC@V‐W /S cathodes exhibit high utilization, superior rate capability, decent long‐term cycling stability. Furthermore, experimental analyses theoretical calculations jointly substantiate V‐W N component is more effective in catalyzing long‐chain while V‐WC benefits favorable Li S deposition kinetics. More importantly, pouch cells also fabricated to demonstrate their feasibility applications. This work not only highlights significance tandem catalysis consecutive LiPSs but provides a feasible avenue developing highly efficient electrocatalysts high‐performance

Managing the redox reactions of polysulfides is crucial for improving performance lithium-sulfur batteries (LSBs). Herein, we introduce a progressive theoretical framework: balanced d-band model, which based on classical center theory. Specifically, by optimizing position in middle between highest occupied molecular orbital (HOMO) and lowest unoccupied (LUMO) each sulfur species, fast oxidation reduction species can be achieved simultaneously. To validate this theory, synthesized catalyst featuring an situ phosphorized heterostructure (NOP) nickel oxide (NiO), effectively optimizes at HOMO LUMO species. Aided kinetics NOP-based cell high reversible capacity, superior cycling stability, prolonged cycle life. This study extends conventional theory introduces innovative model to expand our understanding internal reaction mechanisms LSBs.
