Spent LIBs, rich in lithium, present a promising alternative for lithium extraction, providing both environmental and economic benefits. This review underscores the significance of lithium recycling and systematically examines recent advances in extraction processes, focusing on the extraction of lithium salts from spent cathode and anode materials, while addressing key challenges such as impurity control. Further, innovative lithium reintegration pathways, particularly direct regeneration methods utilizing carbonate salts are reviewed. By broadening the scope of extracted lithium compounds beyond conventional carbonates, how expanding extraction media can enhance the feasibility of a closed‐loop lithium supply is demonstrated. The proposed “lithium extraction‐reintegration” framework not only improves resource circularity but also establishes a foundation for securing lithium in the battery economy.

In this review, the latest advances in enzyme‐mimetic SACs for NH3 synthesis are comprehensively summarized and highlight the significance of enzyme mimicry from four key aspects, including active sites, multi‐enzyme complexes, substrate‐binding pockets, and electron/proton transfer pathways. The fundamentals of SACs are first introduced, highlighting their unique advantages and outlining state‐of‐the‐art design strategies and modification methods for performance optimization. The structural characteristics and catalytic mechanisms of nitrogenase, nitrate reductase, and nitrite reductase are then delved into, and elucidate their inspiration for SAC design. Most importantly, representative examples in enzyme‐mimetic SACs for electrochemical nitrogen and nitrate reduction reactions are presented and discuss how multi‐level enzyme mimicry enhances their activity, selectivity, and stability. Additionally, the key design principles of enzyme‐mimetic SACs are summarized, providing guidance for the development of efficient and durable SACs.

Thermal evaporation is a solvent‐free, scalable, and industrially relevant method, yet despite its many advantages, this method is limited by the lack of additive engineering strategies for controlling the growth of perovskite layers. Here, a novel additive engineering strategy is reported that enables the complete conversion of precursors to a perovskite phase during the two‐step deposition of formamidinium lead triiodide (FAPbI3). The approach is based on the co‐evaporation of potassium‐containing additives (KI and KSCN) alongside PbI2 during the first deposition step, followed by the evaporation of formamidinium iodide. It is demonstrated that the absence of additives leads to an incomplete conversion with a substantial amount of unconverted PbI2 remaining at the buried interface. On the other hand, the co‐evaporation of the additives improves the conversion process, leading, in the case of KSCN, to phase‐pure α‐FAPbI3 with improved microstructure. The additive‐engineered p‐i‐n devices achieve efficiencies up to 18.34%, among the highest reported for evaporated FAPbI3 solar cells without interfacial passivation. This work highlights the great potential of additive engineering for controlling the film formation of thermally evaporated perovskites.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"4 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603382","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}

Despite years of exploration and development, a clear and systematic understanding of the underlying mechanisms of various separators is still lacking in the field. Herein, this article reviews the research advances and development status of separator modification strategies for AZMBs, with a focus on their key roles and mechanisms. In principle, these mechanisms encompass electric field distribution, ion sieve effect, crystal orientation, and desolvation effect.

However, traditional systems are often limited by inefficient charge separation, inadequate utilization of hot electrons, and non‐specific reaction sites, resulting in suboptimal H₂O₂ production. Here, we present a catalyst architecture that achieves high‐density hot‐electron generation with stepwise charge transfer directed to oxygen reduction sites, boosting H₂O₂ photosynthesis. The catalyst comprises ZnIn₂S₄ (ZIS) nanosheets integrated with two non‐noble plasmonic semiconductors, W18O49 nanoneedles and MoO3‐X nanosheets. This configuration leverages dual sites for localized surface plasmon resonance (LSPR) to amplify hot‐electron production while enabling sequential charge migration through the double S‐scheme, guiding electrons to reduction sites while minimizing recombination. The optimized Dual‐LSPR‐Double‐S‐Scheme (DLDS) catalyst exhibits a superior H2O2 production rate of 51.3 µmol g⁻¹ min⁻¹ under UV–vis light and 13.6 µmol g⁻¹ min⁻¹ under visible light. Spectroscopic analyses (fs‐TA, XPS, in‐situ DRIFTS) confirm rapid carrier dynamics, efficient hot‐electron accumulation, and formation of reactive oxygen intermediates (*O₂⁻, *OOH) at targeted sites. Theoretical calculations reveal enhanced local electric fields from dual LSPR, corroborating accelerated hot‐electron migration. The produced H₂O₂ is further evaluated for practical applications, including the detoxification of poisoned plants and bacterial inactivation, demonstrating its potential in environmental remediation.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"74 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594052","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}

Despite robust water adsorption/dissociation and moderate H* adsorption, NiMo alloys are plagued by competitive OH* adsorption, which induces H* site‐blocking, thereby impeding the Volmer step and necessitating large overpotentials. Here, an integrated electrode design is developed by incorporating NiMoCu catalysts onto a stainless‐steel mesh (SSM) through Cu alloying. The optimized NiMoCu achieves a current density of 500 mA cm−2 at only 175 mV overpotential, nearly 19.5 and 6.9 times higher than NiMo and Pt/C, respectively. In situ characterizations and theoretical calculations reveal that segregating H* and OH* adsorption sites (Ni─Cu for H* and Mo for OH*) effectively mitigates H* site‐blocking. This segregation optimizes the short‐range adsorption of various intermediates, thereby enhancing the kinetics from Volmer to Heyrovsky step. Moreover, the regular 3D micrometer‐scale structure of SSM support promotes long‐range mass transfer, further improving the overall performance. When paired with NiFe LDH for anion‐exchange‐membrane (AEM) water splitting, the NiMoCu(−)||NiFe LDH(+) electrolyzer delivers 2 A cm−2 at 1.98 V, with robust durability. This strategy is extendable to NiMoCo and NiMoZn catalysts, offering a universal approach for efficient hydrogen production.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"44 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603383","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}

This study establishes a quantitative link between potential degradation—specifically open‐circuit voltage (VOC) and quasi‐Fermi level splitting (QFLS)—and the photo‐thermal stability of PSCs. It is highlighted that an increase in non‐radiative recombination losses induces the seemingly negligible decrease in VOC and QFLS, though it causes a significant decrease in fill factor (FF) and/or short circuit current (JSC) instead, leading to an overall performance decline. By combining non‐destructive photoluminescence imaging and drift‐diffusion simulations, it is revealed that during photo‐thermal ageing, unstable low‐dimensional passivation fails within tens of hours, generating bulk defects, while unstable hole‐transport‐layer contacts induce interface defects within hours. Building on these findings, a robust hole‐transport‐layer polymer interface is employed and enhanced perovskite crystal quality to suppress both interface and bulk defect generation during ageing, achieving a T80 lifetime exceeding 1000 h under accelerated ageing conditions (85 °C and two‐sun illumination).","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"12 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593859","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}
