Herein, we report an in situ electroreduction approach to construct permanent interlayer Zn-enolate coordination bridges in a multicarbonyl COF (namely, Tp–PTO), concurrently improving conductivity, specific capacity, and cyclability. Benefiting from a “C–O···Zn···O–C” bridging scaffold, abundant redox sites, π-conjugated structure, and smooth ion transport channels of Zn-bridged Tp–PTO COF, a Zn2+/H+ costorage process with a high capacity and fast kinetics is achieved. Moreover, a unique alternant “H+ → Zn2+ → H+” binding–detaching mechanism was revealed. Consequently, the Zn-bridged Tp–PTO COF demonstrated a high specific capacity (223 mAh g–1 at 0.1 A g–1) and long cycling stability (139.3 mAh g–1 after 10000 cycles at 5.0 A g–1). This work underscores the immense potential of the in situ metal coordination bridging strategy in enhancing the comprehensive performance of the COF-based electrode for advanced aqueous batteries.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"54 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we demonstrate an ionic structured polymeric sulfur (IP-S) as a redox mediating matrix, which provides structural stability, an ionic conductive pathway, and a uniform distribution of active materials within the electrode. In particular, the cationic structure of IP-S was attributed to the facilitated LiPS conversion kinetics with the high utilization of sulfur. Consequently, the IP-S electrode delivered the high specific capacity of 1398.8 mAh gsulfur–1 with a low-capacity fading rate of 0.071% over 400 cycles. Moreover, with a high sulfur loading (6.87 mgsulfur cm–2), the IP-S electrode achieved a high initial capacity of 7.23 mAh cm–2. Therefore, this work provides the rational design of ionic structured polymeric sulfur for high performance LSBs as well as the correlation between the ionic structure and the electrochemical property.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"108 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143853253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional Zn anodes face challenges such as slow interfacial kinetics and structural collapse at high rates and Zn utilization. Here, we design an integrated Zn anode with an embedded heterophase boundary framework (HPF-Zn) that could regulate the chemical environment and charge transport kinetics for uniform, fast Zn deposition. Well-designed in situ Raman spectra clearly visualize the dynamic interface evolution under various conditions, confirming rapid Zn2+ replenishment at the interface for HPF-Zn anode. Consequently, the HPF-Zn anode achieves 60× the cycle life of conventional Zn anodes with nearly 100% Zn utilization. Zn||V2O5 full cells exhibit excellent cycling stability, retaining 80% capacity over 5500 cycles (N/P = 5.6) and 2500 cycles (N/P = 3.2). Moreover, Ah-level pouch cells demonstrate superior durability.

However, these batteries face significant challenges, particularly rapid capacity degradation that currently limits their practical implementation. This comprehensive review critically examines three fundamental issues affecting AFSSBs: nonuniform lithium nucleation on bare current collectors, unstable interfaces between plated lithium and sulfide electrolytes, and formation of interfacial voids during cycling. We systematically evaluate recent strategic advances in addressing these challenges, including metal seed coatings, conversion reaction-based compounds, and carbon-based interlayers. The review also analyzes the crucial role of advanced characterization techniques, from cryo-FIB-SEM to operando methods, in understanding failure mechanisms and validating improvement strategies. Finally, we present a forward-looking perspective on research directions necessary for commercialization. This work provides a thorough framework for understanding and advancing sulfide-based AFSSBs toward practical applications in next-generation energy storage systems.","PeriodicalId":16,"journal":{"name":"ACS Energy Letters ","volume":"49 1","pages":""},"PeriodicalIF":22.0,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143846533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ni-rich SC-NMC samples with various compositions, sizes, and shapes are synthesized and investigated for their influence on FC performance. We reveal the necessity of utilizing smaller SCs (<1 μm) as larger sizes (>2 μm) experience significant particle-level lithium concentration gradients under FC conditions. To improve lithium transport and minimize side reactivities, we strategically expose the (104) crystal facets on the surface. Exceptional performance was observed on an optimized SC-LiNi0.80Mn0.05Co0.15O2, delivering a discharge capacity of 165 mAh/g even after 150 cycles at 6C charge.
