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.

Because of its excellent energy density and specific capacity, lithium-sulfur batteries (LSBs) are considered one the most promising storage devices. However, shuttle effect slow transformation polysulfides hinder their practical application. To address effect, we used a Gd-MOF precursor for high-temperature carbonization to obtain GdS@C composite as modification layer LSB separators. The strong affinity metal sulfide sulfur enhances chemical anchoring catalyzes transformation. By employing separator material, effectively suppressed improved electrochemical performance. Under load 3 mg cm-2, initial discharge capacity with GdS@C-modified was 888.9 mAh g-1 at 0.5 C; after 500 cycles, it remained 435.6 retention rate 49.0%. With an increased loading 5 first cycle 0.1 C reached 908.4 g-1; 100 still 743.9 impressive 81.9%. These results demonstrate that material significantly performance LSBs showcases broad application potential.
