Multifunctional Molybdenum Disulfide Nanoarchitectures for Advanced Lithium‐Sulfur Batteries: Comprehensive Strategies for Cathode Catalysis, Separator Modification, and Anode Stabilization

Abstract Lithium‐sulfur (Li‐S) batteries have garnered significant attention due to their exceptional theoretical energy density (2600 Wh kg ⁻¹ ), utilization of earth‐abundant sulfur resources, and environmental compatibility. However, their practical implementation faces substantial challenges, including shuttle effects, sluggish sulfur redox kinetics, and uncontrolled lithium dendrite formation. Molybdenum disulfide (MoS ₂ ) nanosheets are demonstrated to serve as a versatile catalytic platform to concurrently mitigate these fundamental limitations. This comprehensive review aims to systematically summarize recent advances in MoS ₂ ‐engineered modification strategies across three key domains: 1) sulfur cathode hosts for enhanced electrocatalysis, 2) functional separator/interlayer designs, and 3) lithium anode stabilization approaches. Furthermore, persistent challenges are critically analyzed, and strategic research directions are proposed for optimizing MoS ₂ ‐engineered systems, aiming to design high‐energy‐density and long‐life Li‐S batteries in the future.
