Abstract Lithium-sulfur batteries (LSBs) have garnered significant attention as a promising next-generation rechargeable battery, offering superior energy density and cost-effectiveness. However, the commercialization of LSBs faces several challenges, including ionic/electronic insulating nature active materials, lithium polysulfide (LiPS) shuttle effect, volume expansion/contraction cathode, issues with Li metal anode. Despite numerous efforts to address these previous studies predominantly been conducted under mild conditions such high electrolyte-to-sulfur (E/S) ratio, low sulfur loading, excess metal, which cover related for realizing high-energy–density LSBs, practical E/S limited are essential. Under conditions, increased current on higher LiPS concentration exacerbate anode dendrite growth, dead Li, reactivity electrolyte, LiPSs. These problems lead rapid failure significantly impacting electrochemical performance LSBs. Consequently, protecting is crucial This paper introduces challenges associated in reviews research focused each battery component: anode, separator/interlayer. Finally, we discuss future directions component towards Graphical

Abstract Lithium‐sulfur batteries, despite being a promising solution for next‐generation secondary require substantial efforts to overcome the challenges of sluggish sulfur redox kinetics, polysulfides shuttling, and Li metal instability before achieving practical viability. Conventional strategies that utilize catalysts or soluble mediators (RMs) are limited by either impractical producing processes unsatisfactory service life. Herein, an electrochemically active organic material, phloroglucinol – 2,6‐diaminoanthraquinone (PG‐DAAQ) is synthesized through green facile polymerization process better resolve these issues. Serving as RM at cathode, PG‐DAAQ exhibits enduring activity within operating potential window, leading enhanced kinetics utilization. Remarkably, even without any elements, excellent affinity polysulfides, thereby suppressing shuttling facilitating formation more favorable solid‐electrolyte interface stabilize deposition anode. As result, Li‐S cells employing show significantly cycling rate performances than control cells. Even with low electrolyte‐to‐sulfur ratio 6, pouch deliver reversible discharge capacity 821 mA h g −1 after 100 cycles C/10 rate.

Abstract Olefin‐linked covalent organic frameworks (OL‐COFs) show great promise for visible‐light‐driven photocatalysis. Manipulating atomic‐level donor–acceptor interactions in OL‐COFs is key to understanding their exciton effects this system. Here, three are presented with orthorhombic lattice structures, synthesized via Knoevenagel polycondensation reaction of terephthalaldehyde and tetratopic monomers featuring phenyl, benzo[c][1,2,5]oxadiazole, benzo[c][1,2,5]thiadiazole moieties. These feature tunable interactions, making them ideal studying olefin‐linked systems. Comprehensive analyses, including temperature‐dependent photoluminescence spectra, ultrafast spectroscopy, theoretical calculations, reveal that stronger lead reduced binding energy ( E b ), accelerated dissociation, longer‐lived photogenerated charges, thereby enhancing photocatalytic performance. Notably, The TMO‐BDA COF, the lowest , demonstrates superior activity one‐pot sequential transformation excellent catalytic performance gram‐scale reactions, highlighting its potential practical applications. This work provides valuable insights into regulating effect at molecular level OL‐COFs, offering pathways enhance efficiency.
