Here we introduce an interfacial stress–electronic coupling framework that links interfacial coordination constraints with electronic modulation in catalytic systems. Using a low-temperature molten-salt pyrolysis strategy, we construct hollow porous carbon nanocages hosting asymmetric dual single-atom centers (FeN4 and ZnN3S1) closely integrated with Zn0.73Fe0.27S nanoparticles, yielding a hierarchical porous catalyst, denoted as FeZnS-NSC. The nanoparticles act simultaneously as interfacial stress inducers and electronic coupling mediators, accompanied by measurable Fe–N (1.84 → 1.77 Å) and Zn–N (2.01 → 1.84 Å) bond compression and downshifting the d-band center. Multiscale simulations and operando spectroscopy reveal that this dual coupling optimizes *OH desorption and lowers the ORR rate-determining barrier from 1.31 to 0.55 eV. Consequently, FeZnS-NSC surpasses Pt/C (E1/2 = 0.92 vs. 0.87 V) and delivers record-breaking Zn–air battery performance, achieving a peak power density of 525 mW cm−2 in the quasi-solid-state. In liquid-state devices, it delivers an unprecedented open-circuit voltage of 1.62 V and an ultralong cycling stability exceeding 1300 h, representing the highest values reported to date for non-precious-metal electrocatalysts. These findings establish an “interface stress–electronic coupling” paradigm for non-precious metal catalysis and underscore porous nanocage confinement as a universal strategy for high-performance electrochemical energy devices.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"72 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149152706","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}

Here, we establish a continuous optical-electrical field-diagnostic framework that separates shared environmental modulation from persistent cell-specific failure and tests optical timing, transferability and predictive value. We monitored encapsulated perovskite cells in Alpine and Mediterranean climates using synchronised electrical, spectral, thermal, humidity and passive RGB measurements. A fixed C1/C3 peer reference removed the dominant cohort-wide response and exposed four persistent Alpine terminal failures; seasonal recovery of both reference cells showed that the deep winter minimum was predominantly reversible. An analysis-locked retrospective colour replay matched three of four retrospective terminal markers (optical-first offsets of 1, 4 and 6 days), and a locked marker-definition audit then resolved the timing. With an earlier daily-persistent marker, C2 became coincident, C8 electrical-first, and the only optical-first change, at C5/C6, was shared with non-failing C3/C4. The Alpine record therefore establishes day-scale optical-electrical co-evolution around failure, and the same-date C3/C4 control shows that this optical-first change is not device-specific. At Paterna, optical changes occurred 18 and 13 days after electrical onset and did not reproduce the Alpine timing. A date-disjoint hidden test established reliable passive measurement of wetness and thaw, which did not improve three-day health prediction. Endpoint diffraction distinguished PbI<sub>2</sub>-rich photocurrent-loss states from the lower-ratio mixed voltage-current failure. Over the common winter window, Alpine survivors recovered while Paterna C3/C4 declined despite overlapping per-cell integrated yields.

The conversion of glycerol to valuable products on platinum has attracted attention as a substitute for the oxygen evolution reaction in hydrogen-producing electrolyzers, motivated by the availability of glycerol as an inexpensive byproduct of biodiesel production. However, the glycerol oxidation reaction is known to poison platinum, requiring an intelligent operation procedure to sustain high conversion rates. The employed AI controller autonomously discovered a non-periodic pulsing strategy, which achieved on average a 30% higher charge transfer rate over the human-engineered pulsing protocol. In addition, we analyzed its decision-making using first-order Markov-chain modelling. This analysis revealed that the AI employs two distinct surface reactivation procedures: most of the time, it uses a short cycle, pulsing from the glycerol-oxidation potential to a relaxation potential of 0.3 V <i>vs.</i> RHE, while it periodically performs a longer cycle by pulsing first to 1.0 V <i>vs.</i> RHE and then to 0.3 V <i>vs.</i> RHE to revitalize the system. To further support these findings, we developed an interpretable physics-inspired AI model that simulates surface dynamics during glycerol oxidation and captures the evolving distribution of active and poisoned sites. Although demonstrated for glycerol oxidation, both the AI-control framework and the physics-inspired AI model are broadly applicable to other electrochemical systems, offering a general pathway for integrating AI methods into experimental electrocatalytic research.</p>","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":" ","pages":""},"PeriodicalIF":30.5,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13635933/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we critically re-examine three long-standing misconceptions and highlight that they are interrelated in practical operation despite distinct physicochemical origins. Antisite phase transition behavior in Ni-rich cathodes is revisited, and most systems are shown to follow continuous solid-solution pathways with localized heterogeneity rather than true phase transitions. Moreover, the Ni-centric paradigm is challenged, as energy density does not scale monotonically with Ni content but depends on coupled effects of voltage and structural stability. Although originating from different aspects, these issues become strongly coupled during cycling and collectively influence electrochemical behavior. For example, Li/Ni intermixing alters transition-metal-oxygen covalency and oxygen activity, while structural heterogeneity affects reaction pathways inferred from electrochemical signals. These correlations indicate that cation intermixing, oxygen stability, and electrochemical response are tightly linked during operation. This review shifts the design paradigm from intermixing suppression to precise regulation and from composition-driven optimization to mechanism-informed design, enabling high-energy, long-lifetime LIBs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"7 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019738","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 trade-off between recoverable energy density (Wrec) and efficiency () limits existing materials because thermal fluctuations can destabilize nanoscale polar structures and promote hysteretic ferroelectric states. Here, a machine-learning-guided strategy is used to identify a lead-free composition exhibiting a thermally anchored polar heterostructure (TAPH) that mitigates thermal degradation. A predictive model based on structural descriptors identifies 0.6Bi0.47Na0.47Ba0.06TiO3-0.4Bi0.20Sr0.70Hf0.20Ti0.80O3 as the optimal composition. Atomic-scale characterization reveals a heterogeneous polar state comprising tetragonal-, rhombohedral-, and cubic-like nanoregions. Local lattice distortion, Bi-containing bonding environments, and interphase electric and elastic fields are considered to cooperatively hinder the thermally driven coalescence of polar regions, while preserving the dynamic response of local dipoles. This heterogeneous polar state is associated with improved breakdown strength, low hysteresis, and stable high-temperature energy-storage performance.The resulting multilayer ceramic capacitors (MLCCs) deliver a Wrec of 24.12 J cm⁻³ with an η of 95% at 1160 kV cm⁻¹.

However, the isotropic architecture of conventional evaporators often hinders even water delivery and targeted heat extraction, resulting in non-uniform cooling, which further leads to hotspot generation and extra feedwater consumption. Herein, we propose an anisotropic interfacial evaporator mediated by Turing hydrodynamics, which is readily demonstrated by fabricating CuO nanostructures with generative Turing patterns. The as-designed Turing-patterned capillary networks (TCNs) leverage the inherent instability-driven patterning mechanism to construct orientable microchannels, which spontaneously steer water flow by reconfiguring the pressure and velocity fields within the microchannels for directional capillary spreading with enhanced heat transfer across the entire heating surface, thereby achieving uniform interfacial evaporation and homogenizing the surface temperature field. Under 1-sun solar heat input, the TCN evaporator's surface is, on average, 3 °C cooler than that of the isotropic fibrous cooling pad, and the surface temperature inhomogeneity is suppressed to below 0.5 °C. The TCN evaporator not only improves energy efficiency by 13.7% compared to the fibrous evaporator, but also consumes 21.7% less water supply to achieve the same cooling capacity. The economic viability for photovoltaic thermal management by the TCN is also discussed in detail. This work provides a feasible paradigm for the rational design of high-efficiency evaporators by combining generative geometry-adaptive morphogenesis with interface engineering, offering new insights into the development of interfacial evaporation cooling with enhanced water utilization.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"57 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149019682","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}

The thermally stable Fc core and reversible Fc/Fc+ redox couple, combined with carbonyl linkers, enable strong coordination to halide-related defects and tuneable frontier orbital energies, reducing non-radiative recombination and dark current in perovskite solar cells (PSCs) and perovskite photodetectors (PPDs), respectively. However, previous studies have focused on specific applications separately, resulting in a limited understanding of molecular design principles bridging device operating conditions. Here, we holistically investigate phenyl- and furyl-terminated ester- and ketone-linked Fc interlayers in PSCs and PPDs. By incorporating Fc-derivative interlayers, we demonstrate that the identity of the terminal group critically governs interfacial energetics and thereby directs device performance. Phenyl-based Fc interlayers generate a large potential step at the perovskite surface, as evidenced by a work-function (WF) shift. This creates a localized electrostatic barrier to reverse-biased hole injection, suppressing dark current density (JD) and enhancing the signal-to-noise ratio. In contrast, furyl-based analogs cause a negligible WF shift, leaving the interfacial injection barrier unperturbed. Instead, their illumination-induced band bending promotes balanced charge extraction while passivating surface traps. Electrochemical potential differences associated with ketone- and ester-linkers help explain the respective sub-trends, whereby the former enhance PPD performance, whilst the latter are preferred in photovoltaics. Consequently, PSCs modified with ferrocenyl-bis-furyl-2-carboxylate (F2) achieved state-of-the-art power conversion efficiencies (PCEs), reaching 26.51%, while PPDs modified with ferrocenyl-bis-phenyl-2-ketone (Ph1) attained outstanding specific detectivities, reaching 1.1x1013 Jones at -0.5 V (690 nm).

Various interface-engineering strategies have been developed to enhance high-voltage cycling performance of LCO, but they are typically categorized by material composition or manufacturing methods instead of interfacial functions, which obscures the understanding of underlying functions that govern their efficacy and the formulation of general design principles. In this review, guided by degradation mechanisms, we propose a function-based interface design framework that explicitly connects the coupled degradation pathways of high-voltage LCO with the multifunctional roles of engineered interfaces. Representative interface-engineering strategies are systematically categorized according to their interfacial functions, including accelerating Li + transport, enhancing chemical stability, improving structural stability, and alleviating mechanical damage. This function-based framework elucidates the common design principles shared by diverse interface modification strategies, and provides a unified perspective for evaluating their effectiveness. Finally, we outline future research directions, including pratical application-based performance evaluation and scalable production, intelligent and adaptive application, dynamic interphase regulation and advanced operando characterization, artificial intelligence and big data assisted simulation, and function-based interface design, thereby presenting a roadmap for the development of nextgeneration high-energy-density lithium-ion batteries.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"4 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013657","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}
