However, previous studies have predominantly focused on crystal cathodes comprising the octahedral coordination of metal atoms and a well-ordered layered topology. This omits other cathode materials with other structures or coordination that could potentially surpass conventional counterparts in terms of performance. Here, using X-ray diffraction, resonant inelastic X-ray scattering and X-ray absorption near-edge spectra experiments, we investigated an amorphous Li–V–O–F cathode (a-LVOF) with tetrahedral coordination and elucidated an O–O formal redox mechanism at a moderate voltage of 4.1 V, without a conventional octahedral Li–O–Li configuration. The electrochemically amorphized material fosters randomly distributed VO4 units and scattered dangling oxygen bonds, which facilitated O–O binding. Moreover, a-LVOF demonstrates a high capacity of 230 mAh g−1. Our findings reveal a low-voltage O–O formal redox mechanism in an amorphized cathode material.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"14 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677765","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}

Such frustrated coupling manifests as the quantum interference of Josephson currents from different tunnelling channels and becomes tunable if channel transparency can be varied5,6,7,8. To explore these unconventional effects in the prototypical s±-wave superconductor FeSe (ref. 9), we use atomic-resolution scanned Josephson tunnelling microscopy10,11,12,13 for condensate-resolved imaging and junction tuning—capabilities unattainable in macroscopic Josephson devices with fixed characteristics. We quantitatively demonstrate frustrated Josephson tunnelling by examining two tunnelling inequalities. The relative transparency of two parallel tunnelling pathways is found tunable, revealing a tendency towards a 0–π transition with decreasing scanned Josephson tunnelling microscopy junction resistance. The simultaneous visualization of both superconducting condensates reveals anticorrelated superfluid modulations, highlighting the role of interband scattering. Our study establishes scanned Josephson tunnelling microscopy as a powerful tool enabling new research frontiers of multicondensate superconductivity.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"12 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144677764","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}

Hyperfluorescence—in which the excited state created on the thermally activated delayed fluorescence emitter is transferred to a fluorescent terminal emitter with a narrow emission spectrum—is promising towards improving colour purity and stability. However, direct charge trapping on the smaller-gap terminal emitter may lead to direct emissive losses, inhibited charge transport and charge imbalance. Here we demonstrate single-layer pure-blue hyperfluorescent organic light-emitting diodes that are not compromised by charge trapping on the terminal emitter. We reveal that the energetic disorder of the thermally activated delayed fluorescence sensitizer allows for the presence of a terminal emitter with a smaller energy gap, without affecting charge transport. Consequently, the stability benefits of single-layer organic light-emitting diodes can be combined with trap-free hyperfluorescence, resulting in pure-blue emission, a simple device structure, high quantum and power efficiencies, and state-of-the-art operational stability.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"26 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669985","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, most state-of-the-art CILs are constrained by limited conductivity, high recombination and poor morphology, which collectively hinder device efficiency and stability. Here we report an inorganic–organic hybrid CIL (AZnO-F3N), developed by a dual-component synergy strategy, which integrates organic material PNDIT-F3N with two-dimensional amorphous zinc oxide. This design leverages the synergistic interactions between two-dimensional amorphous zinc oxide and PNDIT-F3N, resulting in reduced interfacial defect, enhanced conductivity and improved film uniformity. OSCs incorporating the AZnO-F3N CIL exhibit more efficient charge extraction and transport, along with reduced recombination. Consequently, a D18:L8-BO-based binary OSC achieves an efficiency of 20.6%. The introduction of BTP-eC9 as the third component further elevates the efficiency to 21.0% (certified as 20.8%). Moreover, the CIL demonstrates versatility across various active layers, thick-film configuration and flexible devices, underscoring its great potential to advance OSC technology.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"46 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652558","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}

Knowledge on solvent co-intercalation is relatively scarce and largely limited to graphite anodes, for which in sodium-ion batteries, the co-intercalation of glyme molecules is fast and highly reversible. The use of co-intercalation for cathode active materials (CAMs) remains much less explored. Here we investigate for a series of sodium-layered sulfide CAMs (NaxMS2, M = Ti, V, Cr and mixtures) under which conditions solvent co-intercalation occurs and how this process impacts the phase behaviour, electrode breathing, redox potential and cycle life compared to ‘Na+-only’ intercalation. Co-intercalation is a complex process that can, for example, cause opposing fluxes, meaning that solvents intercalate into the CAMs while sodium ions simultaneously deintercalate. Co-intercalation leads to layered structures that can include different amounts of confined solvated ions, ions and unbound solvent molecules. It is an approach to designing structurally diverse, layered materials with potential applications for batteries and beyond.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"24 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144652562","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 latter holds true if they are compatible with next-generation high-capacity anodes, but most highly ion-conductive solid electrolytes decompose at low operating potentials, leading to lithium loss and increased cell resistances. Here the dynamic stability of solid electrolytes that can improve all-solid-state battery performance is demonstrated. Halide electrolytes Li3YCl3Br3 and Li2ZrCl6, considered unstable at low potentials, are found to exhibit structurally reversible redox activity beyond their electrochemical stability windows, increasing compatibility with anodes and contributing to capacity without compromising ionic conductivity. The benefit of this dynamic stability window is demonstrated with cost-effective red phosphorus anodes, resulting in high reversible capacities (2,308 mAh g−1), high rate capacity retention (1,024 mAh g−1 at 7.75 mA cm−2) and extended cycle life (61% retention after 1,780 cycles). Furthermore, high areal capacity (7.65 mAh cm−2) and stability (70% retention after 1,000 cycles) are achieved for halide-based full cells with red phosphorous anodes. The beneficial redox activity of halide electrolytes greatly expands their application scenarios and suggests valuable battery design principles to enhance performance.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"16 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639937","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}

Achieving simultaneous optimization of both states has remained a challenge. Here we introduce donor–acceptor covalent organic frameworks (COFs) that integrate a dual-state activation strategy. The COFs feature segregated columnar π-arrays, aligned micropores and short donor–acceptor distances. Upon photoexcitation, electron transfer occurs at acceptor units, while energy transfer occurs at donor sites. The porous network also ensures efficient substrate transport to catalytic centres, while intra- and interlayer hydrogen bonding stabilizes excited states, further enhancing photostability and reactivity. This dual-state strategy provides a benchmark for photocatalytic organic transformations, including high turnover frequencies under red-light irradiation, broad-spectrum absorption extending into the near-infrared and operation without metals, co-catalysts or sacrificial donors. By integrating photophysical and structural optimizations, our approach establishes a design strategy that overcomes limitations in solar-driven chemical transformations and broadens the scope of COF-based photocatalysis.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"10 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144639938","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}
