Still, it suffers from a trade-off between activity and stability due to excessive Ru-O covalency, which exacerbates lattice oxygen loss via the lattice oxygen mechanism (LOM). In this study, we introduce a synergistic approach by incorporating cobalt single atoms and RuO2/TiO2 heterointerfaces on RuO 2 clusters (CoSA-RuO2/TiO2) to modulate Ru-O covalency.This strategy facilitates a domainant adsorbate evolution mechanism (AEM) and regulates interfacial water dissociation, enhancing both intrinsic activity and stability.The optimized design achieves an ultralow overpotential of 151 mV at 10 mA cm-2 for acid oxygen evolution reaction (OER) and demonstrates remarkable durability of 1000 hours in a PEMWE cell under pulsed currents (0~100 mA cm-2). In situ/operando characterizations and theoretical calculations reveal that the Co-SAs and RuO2/TiO2 heterointerfaces extend the Ru-O bond and reduce the Ru oxidation state. This optimized electronic structure weakens Ru-O covalency, stabilizes lattice oxygen, and suppresses LOM, favoring a dominant AEM pathway. Moreover, the engineered interface reduces the interfacial hydrogen-bonding network, as revealed by ab initio molecular dynamics (AIMD), thus facilitating water dissociation and accelerating proton transfer kinetics. This work underscores the potential of precisely modulating metaloxygen bonds through interfacial and single-atom synergy to overcome the activitystability challenge in oxide electrocatalysis.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"4 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148877535","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 review systematically traces the development of three major ASE families-sulfides, oxides, and halides-analyzing their microstructural features across short-range, medium-range, and long-range length scales, and categorizing them into three representative structural models, namely the continuous random network (CRN), molecular cluster (MC), and random close packing (RCP) models.Based on this framework, we comprehensively evaluate the ionic and electronic conductivities, electrochemical stability windows, and cycling lifespans of these systems. Furthermore, we examine their mechanical stability in terms of stress dissipation and interfacial compliance, thermal stability with respect to glass transition and crystallization resistance, and air stability focusing on hydrolysis mechanisms and mitigation strategies. By comparing the distinct structure-property correlations across sulfide, oxide, and halide ASEs, we highlight the multifaceted role of amorphization in modulating electrochemical performance and physicochemical stability, and offer perspectives on future directions including thermal metastability control, structural disorder quantification, air stability testing standardization, and gradient amorphization design.Broader context:The sustained consumption of non-renewable resources and the rapid expansion of electric vehicles are driving an urgent demand for energy storage technologies that combine higher energy density with intrinsic safety. Conventional lithium-ion batteries rely on flammable liquid electrolytes, whose inherent limitations in both safety and electrochemical stability window restrict their advancement toward higher voltage and higher energy density. All-solid-state batteries (ASSBs) employing non-flammable, mechanically robust solid electrolytes (SEs) with a wide electrochemical stability window offer a viable pathway to achieving safety, compatibility with lithium metal anodes and high-voltage cathodes, and consequently enhanced energy density. However, the intrinsic grain boundaries in crystalline solid electrolytes (CSEs) can, under coupled mechanical, electrical, thermal, and chemical fields, induce multiple failure modes. ASEs, characterized by the absence of grain boundaries and structural disorder, have garnered increasing attention in recent years. Owing to their GB-free isotropic networks, ASEs can improve ionic transport and mechanical compliance, while their metastable nature leads to distinct thermodynamic behaviors across different systems.

Among the components of AZIBs, the zinc anode has attracted significant attention owing to its high specific capacity and favorable thermodynamic stability in aqueous electrolytes. Although water in the electrolyte contributes to the high safety of AZIBs, its reactive nature also induces a series of undesirable side reactions in the zinc anode, such as hydrogen evolution, zinc corrosion, and surface passivation. These issues lead to poor interfacial stability and limited cycle life, significantly hindering the practical application of AZIBs. Given these challenges, this review conducts a systematic analysis from the perspective of water molecules. The physicochemical characteristics of water molecules, the solvation structures, the hydrogen-bonding network, and their collective influence on the electrochemical behavior of zinc anodes are examined. The interrelated mechanisms of water-induced effects are systematically summarized. Furthermore, recent advances in electrolyte design and interfacial engineering strategies aimed at modulating water behavior are critically discussed. This review will deepen the understanding of water's role in AZIBs and offer strategic guidance for the development of high-performance aqueous battery systems.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"135 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148877538","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 decipher the fundamental degradation mechanisms of SMA-based photocathodes and identify polymerized SMAs (PSMAs) as critical photoactive materials for achieving long-term operational stability. A systematic comparison between a prototypical SMA-based BHJ (PM6:Y6) and its polymerized counterpart (PM6:PY-IT BHJ) reveals two decisive advantages of PSMA-based systems. First, the high-lying energy levels of PY-IT establish favorable energy level alignment with the water reduction potential across a wide pH range, thereby facilitating charge transfer from the BHJ to the catalyst layer. Second, the PSMA-based BHJ exhibits superior morphological resilience against electrolyte infiltration owing to suppressed molecular diffusivity, which effectively inhibits detrimental long-range phase separation. Consequently, the optimized PM6:PY-IT photocathode demonstrates outstanding durability, retaining 92% and 68% of its initial performance after 12 h and 40 h of continuous operation, respectively, with a Faradaic efficiency of 97.8 ± 2.6%.

Currently, optimization restarts with each new material, and progress could be significantly accelerated by obtaining comparable, material-independent and readily measurable predictive proxies. Aiming to identify such transferable properties linking molecular structure to macroscopic device performance, we built on the frameworks of Kasha and Spano to extract robust, physically meaningful microstructural proxies directly from UV-vis spectra via the quantitative analysis of vibronic structures. We generated a large dataset pairing five state-of-the-art polymer donors (D) and five non-fullerene acceptors (A) in a combinatorial grid with a wide range of process conditions tested for solar cells of each donor–acceptor (D:A) pair. We then developed a generalized spectral deconvolution routine to extract reliable optical features. Leveraging these features, we applied Gaussian process regression (GPR) to predict current–voltage characteristics. Crucially, the model successfully extrapolated to untrained, novel material combinations, achieving a mean absolute percentage error (MAPE) below 10%. Additionally, all solar cells were degraded under accelerated conditions, and the short circuit current losses could be directly correlated to aggregation features of the acceptor. This work provides significant progress toward the creation of digital twins for OPV, leading to the possibility of inverse molecular design and acceleration in optimizing efficiency and stability.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"16 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148877543","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, the scalable deployment of renewable fuels is hindered by complex, often competing interdependencies between production economics, resource efficiency, life-cycle emissions, and strict engine compatibility requirements. We present a holistic optimization-based design framework that integrates process, product, and energy supply for optimal renewable drop-in fuel production for both gasoline- and diesel-powered engines. We consider a comprehensive portfolio of production pathways, including biomass-to-liquid, fermentation, and power-to-liquid pathways, and simultaneously optimize the chemical process, fuel composition, and energy system. We demonstrate that combining pathways in hybrid integrated process concepts consistently achieves higher cost and resource efficiency than standalone fuel production pathways (e.g., power-to-liquid), while simultaneously satisfying fuel properties for drop-in use. The rigorous energy integration improves energy efficiency and, assuming a renewable electricity mix and green hydrogen availability, reduces greenhouse gas emissions by a factor of 20 relative to fossil benchmarks. In addition, high resource efficiency enables low cost premiums (22–39%) compared to lignocellulosic ethanol production. Our analysis reveals that renewable hydrogen and electricity supply are the dominant drivers of fuel costs and emissions, outweighing other feedstocks such as biomass. Furthermore, we quantify the economic potential of relaxing fuel property specifications, and show how co-producing multiple fuels in integrated production plants can have advantages for fuel production at a fleet level. These findings highlight the necessity of holistic approaches to identify viable, resource-efficient pathways for sustainable fuel production.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"74 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853682","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, both the solubility behavior and interfacial chemistry of this emerging electrolyte configuration remain insufficiently understood. Building on the recently established solubility-inverted behavior of LiPF6 in glyme ethers, here we show that breaking the molecular symmetry of glyme ether solvents reduces the propensity for ordered Li(ether)xPF6 solvate-crystal formation and thereby enables practical-concentration LiPF6-glyme ether electrolytes. Asymmetric fluorination of diethoxyethane (DEE) to form F5DEE increases the LiPF6 solubility from <0.1 M in DEE to 2.0 M in F5DEE. More importantly, we establish a molecular-level framework for SEI formation in LiPF6-glyme ether electrolytes and reveal a solvent/anion-decoupled interfacial regime in which SEI chemistry is dominated by solvent decomposition, with only limited detectable contribution from PF6−. This understanding suggests that the SEI in LiPF6-glyme ether electrolytes should be regulated primarily through molecular engineering of glyme solvents and electrolyte additives rather than relying on PF6− decomposition. As a demonstration, the fluoroethylene carbonate (FEC) additive preferentially undergoes reduction, thereby suppressing F5DEE decomposition and substantially improving lithium reversibility while retaining the high-voltage advantages of LiPF6. The resulting electrolyte enables stable Li||NCM811 cycling at cut-off voltages up to 4.8 V. More broadly, this work establishes molecular-level design principles for both phase behavior and interphase chemistry in emerging LiPF6-glyme ether electrolytes toward high-voltage lithium metal batteries.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"37 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148853618","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}

A moisture-permeable membrane converts real seawater feed into water vapor directly usable for electrolysis while physically excluding non-volatile ions, avoiding direct liquid-water feeding to the gas channels and protecting the MEA from seawater-derived degradation. Mechanics–transport–reaction co-optimization of the anode assembly homogenized MEA compression and organized gas transport, lowering both ohmic and charge-transfer resistance and enabling 420 mA cm-2 at 2 V and 200 h seawater durability at 400 mA cm-2 under real seawater feed. The architecture confines seawater-side degradation to a low-cost replaceable membrane, while reducing water-supply-pathway exergy destruction by 90.5% relative to an evaporation–condensation–reheating route.

Conventionally, evaluating and optimizing FAPbI3's phase stability requires extensive aging tests, making the process time-consuming and labor-intensive. Here, we develop a predictive model that evaluates FAPbI3's phase stability using a small set of fingerprints extracted from fresh films, thereby shifting stability evaluation from prolonged aging experiments to rapid, fresh-stage characterization. The model is established through a data-driven approach that integrates an automated experimentation platform with machine-learning algorithms, enabling identification of the most informative crystallographic predictors and quantification of their coupled contributions to phase stability. Among all diffraction-derived features, the area of the (221) peak, the full width at half maximum of the (220) peak, and the area of the (111) peak emerge as the three most influential predictors, together explaining 72% of the variance in the degradation rate constant. The results suggest that phase-stable α-FAPbI3 is primarily associated with high crystallinity, while preferred orientation and reduced peak broadening provide additional contributions. Importantly, the predicted thin-film phase stability is reflected in corresponding trends in solar-cell durability under combined moisture, heat, and light stresses.
