These limitations arise from an implicit assumption that electrolyte properties are dictated by molecular identity or bulk-averaged coordination interactions. However, growing evidence reveals that electrolytes are intrinsically structured media, where ion aggregates, solvent-segregated domains, percolation networks, and interfacial enrichment layers collectively define electrochemical behavior. Here, we establish organized molecular assemblies as a unifying framework to decode and engineer this structural dimension. Driven by correlated noncovalent interactions, electrolytes evolve into spatially organized systems in which solvation topology, mesoscale connectivity, and interfacial ordering are intrinsically coupled. Within this framework, electrochemical performance emerges not only from composition, but from the correlation of structure across multiple length scales, providing a structural origin for resolving long-standing trade-offs between conductivity and stability, mobility and robustness, and solvation strength and interfacial kinetics. This review systematically elucidates the interaction mechanisms governing multi-scale assembly and constructs a structure-topology-function paradigm linking molecular organization to ion transport, reaction selectivity, and interfacial stability across aqueous, nonaqueous, and solid-state electrolytes. Ultimately, electrolyte design is reframed as the control of spatially and temporally correlated molecular organization, establishing organized molecular assemblies as a generalizable strategy for engineering next-generation energy storage systems with programmable reactivity and dynamic response.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"15 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149013656","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, recent developed Pt-based catalysts with small particle sizes suffer from a persistent activity-durability trade-off because highly accessible Pt surfaces are vulnerable to oxidation and dissolution. Here, we present a scalable Co-tannic acid (TA) coordination strategy that directly upgrades commercial Pt/C into graphitized carbon veil (GCV) Pt3Co by thermally converting a complex into a Pt-Co surface alloy and thin GCV while modifying the carbon surface. This integrated structure improves oxygen reduction activity, lowers local oxygen transport resistance and facilitates water removal while preserving reactant accessibility. Under heavy-duty operation, GCV-Pt3Co achieves a peak efficiency of 72%, high rated power density (1.21 W/cm 2 @0.67V). Also, GCV-Pt3Co exhibits outstanding durability under long-term operation. After accelerated durability test (ADT) cycles, it retains a Pt utilization of 3.95 kW/gPt and markedly extends the ADT projected lifetime to 27,800 h.

Here, we reveal the structural and optoelectronic evolution of formamidinium-caesium lead-halide perovskite films under heat and/or light using in-situ X-ray diffraction and photoluminescence. Heat and light combined induce much faster degradation than either stressor alone, with 1-sun illumination degrading material 53 times faster at 85°C than room temperature. For all compositions investigated the degradation rate is highly nonlinear in time and follows a sigmoidal decay, suggestive of interface-driven dynamics. Degradation proceeds in three steps: halide segregation (for mixed-halide perovskites), A-site cation diffusion triggered by heterogeneity and strain, and finally iodine and formamidinium loss. Our findings provide a quantitative framework for lifetime predictions and highlight the necessity of combined heat and light ageing tests.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"269 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148980707","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}

Combining them on a single surface under an imposed heat load is intrinsically difficult, as hotspot cooling raises the emitter temperature, whereas condensation requires sustained sub-dew-point regions. Here we establish, to our knowledge, a previously unreported geometry-driven co-functional regime in which a localized hotspot is coupled to an extended planar or pyramidal radiative emitter. Lateral heat spreading creates a warm, dry zone near the hotspot while preserving cooler peripheral regions for dew formation, allowing the same passive platform to reject heat and harvest water simultaneously. We combine angle-resolved optical characterization, raytracing, coupled heat and mass transfer modelling, and outdoor experiments. At a hotspot heat flux of 1021 W m-2, the largest planar emitter and 45° pyramidal emitter retain dew fluxes of 9.3 and 7.9 g m-2 h-1, respectively, while lowering the near-hotspot temperature by more than 45 °C relative to a non-concentrated control. At 1500 W m-2, the same architectures keep the hotspot below 20 °C, whereas the control approaches 85 °C. Finally, an experiment-calibrated global assessment further identifies where this regime is climatically accessible.

The current best Li-NRR performance requires elevated N2 pressures (PN2) ≥10 bar in model three-electrode cells, though practical electrolysers would benefit from operation at close to ambient PN2. To enable this, we designed an electrolyte containing a high concentration of trihexyltetradecylphosphonium bis(trifluoromethylsulfonyl)imide, [P6,6,6,14][NTf2], and used it for the Li-NRR mediated by LiNTf2 under flowing N2 at 1-2 bar. Under these conditions, the 1.5 LiNTf2 + 0.65 M [P6,6,6,14][NTf2] + 0.1 M ethanol combination produced NH3 at a faradaic efficiency of 90 ± 5% (0.05 cm2 electrode) and 83 ± 9% (1.2 cm2 electrode), contrasting ca 36% for the conventional [P6,6,6,14][NTf2]-free electrolyte. Our data suggest that high-concentration [P6,6,6,14][NTf2] inhibits side reactions and thereby improves the Li-NRR performance. Moreover, the hydrophobic nature of [P6,6,6,14]+ enabled stable Li-NRR when the cell was assembled in air and in the presence of water. This opens a pathway for the future integration of the Li-NRR with a water oxidising anode for sustainable ammonia production.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"152 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148980703","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 failure stems largely from a pronounced Young's modulus (E) mismatch across multilayer stacks, which intensifies stress localization and triggers catastrophic, electrically disruptive cracking. Here, we report an E-gradient shear-lag design that stabilizes IS-PSCs by strategically converging the E values of both the substrate and perovskite layer toward the intermediate E of the PH1000/NiOx electrode region (4.70 GPa). This is achieved by stiffening the thermoplastic polyurethane (TPU) substrate through increased hard-segment fraction, increasing E from 199 to 1560 MPa, while softening the perovskite film via TPU additive engineering, reducing E from 19.2 to 8.39 GPa. This mechanically graded architecture suppresses strain localization and redistributes tensile stress, thereby preserving the continuity of carrier transport even under significant deformation. Consequently, the optimized IS-PSC achieves a power conversion efficiency of 22.14% (certified: 21.52%) and retains 80% of its initial performance at 60% tensile strain, demonstrating the efficacy of E-gradient engineering in overcoming the inherent brittleness of perovskite photovoltaics.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"59 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148980708","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, their rotating single-bond linkers (e.g., β-ketoenamine) often lead to structural distortion with high redox barriers, hindering full utilization of active sites and thus unsatisfactory capacity. Here we propose a β-ketoenamine-bond confinement strategy to construct near-planar quinone polymer cathodes through integrating 2,4,6-triformylphloroglucinol with different diaminoanthraquinone isomers. Shifting the amino groups on diaminoanthraquinone unit from ortho to para-position mitigates repulsive interactions between neighboring carbonyl groups and polymeric β-ketoenamine linkers, suppressing structural distortion to yield a near-planar quinone skeleton (2,6-DT) with a dihedral angle of 178.4° (vs. 134.1°/160.1° for ortho-/meta-substituted 1,2‑DT/1,5‑DT). This feature enables low-energy-barrier redox reaction (0.14 eV) to promise full utilization (96.8%) of multielectron carbonyl groups in 2,6-DT (vs. 0.25 eV/68.5% of 1,2-DT and 0.19 eV/84.9% of 1,5-DT). Furthermore, the extended near-planar structure of 2,6-DT promotes robust intramolecular π-π stacking (5.93 eV vs. 4.63/5.28 eV for 1,2-DT/1,5-DT), conferring exceptional structural anti-dissolution in aqueous electrolytes. Consequently, 2,6-DT cathode harvests state-of-the-art capacity (313 mAh g−1) and cycling lifetime (80,000 cycles), placing it among the leading reported IOBs. Our findings provide new insights for designing near-planar polymer structures via single-bond-confined engineering towards better IOBs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"76 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148973565","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}

Stabilization strategies have therefore largely aimed to suppress this low-voltage phase transition. Here, using phosphorus-integrated Li1.67Mn1.5P0.17O4 (LMPO) and phosphorus-free Li1.86Mn1.67O4 (LMO) as a matched model pair, we show that the key to low-voltage reversibility is not preventing tetragonal phase formation, but controlling how the tetragonal phase evolves during cycling. LMPO retains 78.0% of its capacity after 100 cycles, whereas LMO retains only 26.0%, despite both materials forming a discharged tetragonal phase. Combined electrochemical analysis, multiscale structural characterization and first-principles calculations reveal that phosphorus narrows the extended 8a-to-16c two-phase regime and suppresses irreversible tetragonal-phase accumulation. More importantly, phosphorus disrupts the cooperative ordering of Jahn–Teller axes, attenuates MnO6 distortion and reduces the lattice/volume mismatch between cubic and tetragonal phases. These results identify the cooperative character of Jahn–Teller distortion as a critical design target for stabilizing low-voltage cycling in Mn-based spinel cathodes.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"21 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148973571","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}

While glyme electrolytes have enabled stable 3 V-class anode-free sodium batteries (AFSBs), fast degradation has been observed when high-voltage cathodes are used, despite the electrolytes being well suited to such cathodes in half cells. Here, we decipher that the anode poisoning arising from the crossovers of oxidative products, which are non-threatening to the cathodes alone, is the main culprit. This discovery contests the common belief that intrinsic interface instability solely dominates the lifespan of AFSBs. As a mechanistic intervention, introducing 1,3-dioxane (DX) as a co-solvent shifts the oxidation pathway from diglyme towards DX-oriented, which suppresses the accumulation and crossover of the attacking species. Consequently, the optimized electrolyte realizes 80% capacity retention of 4 V-class AFSBs after 500 cycles at −20 °C. These results demonstrate that solvation regulation can reshape electrolyte decomposition pathways and reduce the generation of detrimental crossover species, providing a useful design principle for mitigating crosstalk-induced degradation in high-voltage AFSBs.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":"394 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148973584","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}

In this work, two rheology thickeners, polar ethyl cellulose (EC)-a non-ionic surfactant with amphiphilic characteristics, and non-polar polyisobutylene (PIB) are incorporated in the photovoltaic ink to tune the film formation quality and dynamics. Through a range of rheological and morphological measurements, we find that EC acts as a surface-active agent, reducing surface tension and reversing the Marangoni flow to partially suppress the coffee-ring defects, yet it disrupts the donor/acceptor interactions and introduces directional stripes. In contrast, PIB grants the ink shear-thinning ability to facilitate the spreading of solution to form uniform wet films, whilst it also increases the static viscosity of the ink to kinetically suppress both capillary and Marangoni flows after printing, without altering the molecular packing of donor and acceptor. Consequently, PIB yields excellent uniformity across largearea PM6:BTP-eC9 films and delivers power conversion efficiencies (PCEs) over 19.0% and 18.3% in 100 and 300 -nm thick devices respectively, whilst maintaining the PCE of 17.6% for 1 cm 2 device, which are among the highest values for blade-coated binary OSCs.
