Lithium–sulfur (Li–S) batteries have been considered as one of the effective alternative energy systems to commercial lithium-ion (LIBs) due their high theoretical density (2600 Wh kg–1), specific capacity (1675 mAh g–1), low cost, and abundant reserves sulfur.

Abstract Metal‐sulfur batteries (MSBs) are emerging energy storage candidates due to their high density, cost‐effective nature, and environmental compatibility. However, polysulfide shuttling, slow kinetics, dendritic issues severely plague nexus stage from academic commercial applications. Inspired by the low cost higher capacity of metal sulfur batteries, numerous strategies, electrode design separator modification, developed eliminate these challenges on practical grounds. Among them, functionalizing separators hold great promise stabilize battery operation mechanistically in terms safety, stability, electrochemical benchmarks, as existing polyolefin designs cannot fully satisfy complex chemistry polysulfides. This review first discusses critical with associated mechanistic approaches better describe requirement for material manipulation design. Furthermore, role modulated functional materials is critically highlighted screened synergistically achieve an advanced recent four‐year plethora separators. Finally, future directions outlined research. will offer a comprehensive reference new paths designing modulating advancing high‐energy‐density systems.
