Grain boundary precipitation of the controlled distribution of amorphous zirconium oxide microparticles is achieved through the addition of reactive tantalum carbide. During ambient-atmosphere sintering, the carbide decomposes through an in situ reaction, the 'extra' Ta substituting for Zr within the Li6.4La3Zr1.4Ta0.6O12 lattice. Density functional theory (DFT) calculations identify a thermodynamically favourable reaction path and show how substituting Ta5+ at Zr4+ sites affects the crystal structure as well as bulk ionic and electronic conductivities. Quantitative stereology highlights that zirconia also acts as a sintering aid, reducing compact porosity. Cryogenic focused-ion-beam scanning electron microscopy and fractography analysis of cycled solid-state electrolytes illustrates that near-universally observed intergranular Li-metal dendrite propagation is suppressed by the two-phase microstructure, favouring transgranular dendrites instead. Importantly, DFT demonstrates that compared with the Li6.4La3Zr1.4Ta0.6O12 surface, the zirconium oxide surface per se is less electronically conductive and does not trap excess electrons to reduce Li ions. This is a key reason for the substantial improvement in the electrochemical properties over the single-phase baseline.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"26 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145296177","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 FeII/III redox couple charge compensates the cycling of lithium iron phosphate, a positive electrode (cathode) for lithium-ion batteries. High-valent iron redox couples, involving formal oxidation higher than FeIII, could deliver higher electrochemical potentials and energy densities. However, because of the instability of high-valent Fe electrodes, they have proven difficult to probe and exploit in intercalation systems. Here we report and characterize a formal FeIII/V redox couple by revisiting the charge compensation mechanism of (de)lithiation in Li4FeSbO6. Valence-sensitive experimental and computational core-level spectroscopy reveal a direct transition from FeIII (3d5) to a negative-charge-transfer FeV (3d5L2) ground state on delithiation, without forming FeIV, or oxygen dimers. We identify that the cation ordering in Li4FeSbO6 drives a templated phase transition to stabilize the unique FeV species and demonstrate that disrupting cation ordering suppresses the FeIII/V redox couple. Exhibiting resistance to calendar aging, high operating potential and low voltage hysteresis, the FeIII/V redox couple in Li4FeSbO6 provides a framework for developing sustainable, Fe-based intercalation cathodes for high-voltage applications.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":" ","pages":""},"PeriodicalIF":38.5,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145302307","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}

Conventional methods relying on external driving forces, however, exhibit poor control, low yield and limited reproducibility. Here we report spontaneous scrolling in polar van der Waals materials via an electrochemical intercalation/exfoliation process, enabling scalable nanoscroll production. This self-rolling is driven intrinsically by out-of-plane electric polarization (P⊥), where the magnitude of P⊥ is modulated by the intercalant size. Validated across eight polar materials, this approach achieves virtually 100% yield and reproducibility with defined scrolling direction, surpassing external driving force limitations. The nanoscrolls exhibit layer-independent inversion symmetry breaking and coherently enhanced second-harmonic generation, exceeding two-dimensional flakes by ~100-fold and rivalling leading two-dimensional nonlinear materials. Electrochemical initiation further facilitates metal-ion co-intercalation, yielding ten hybrid nanoscroll architectures. These findings establish a scalable route to create one-dimensional nanostructures and hybrid heterostructures, paving the way for designer quantum solids and van der Waals superlattices in quantum nanodevices.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"41 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145283995","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 report a lantern-shaped ribbon-cluster meta-unit that harnesses programmable and reprogrammable elastic energy to achieve over 13 distinct volumetric snapping morphologies from a single unit. Governed by three Euler angles, the meta-unit post-fabrication offers a tunable mechanical design space spanning up to quadrastable states. Unlike single-ribbon or mechanism-based designs, our system autonomously selects snapping pathways via nastic coupling between multiple ribbons, enabling the inverse design of complex snapping morphologies. We harness magnetically actuated bud-to-bloom and tristable morphogenesis to enable fast, non-invasive grasping and remote flow regulation in confined environments. These results establish a general framework for architected materials with programmable shape, stability and function, offering potential applications in soft robotics, deployable devices and mechanical logic.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"2 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145261084","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}
