Herein, we demonstrate that Li/Sn co‐doping in O3‐NaNi 0.5 Mn 0.5 O 2 induces the formation of delocalized Li 2 MnO 3 ‐like domains, deviating from the conventional random substitution model. These domains comprise spatially dispersed Li‐centered local configurations (e.g., LiMn 6 , LiNiMn 5 , LiSnMn 5 ) and serve as structural pillars within the layered framework. Multimodal characterizations reveal that these domains regulate both local structure and electronic configuration. Charge compensation is dominated by Ni redox, while lattice oxygen participation, irreversible oxygen redox, and O–O dimer formation are effectively suppressed. Meanwhile, the stabilized local structure inhibits transition metal migration, mitigates layer gliding, and suppresses c ‐axis contraction, enabling a reversible O3‐P3‐O3 phase transition. The optimized cathode delivers 98.06% capacity retention after 100 cycles at 0.1C and 82.42% after 200 cycles at 1C.

Herein, a temperature‐responsive electrical double layer (EDL) is designed via screening high donor‐number additive, and the EDL composition exhibits temperature‐responsive behavior where elevated temperatures promote anion accumulation and low‐to‐ambient temperatures favor additive enrichment, thereby driving distinct self‐adaptive interfacial chemistries. Experimental and theoretical analyses reveal that low‐to‐ambient temperatures facilitate organic‐inorganic hybrid SEI formation through preferential additive decomposition, whereas high temperatures yield a robust inorganic‐rich SEI via anion decomposition. The self‐adaptive SEIs can significantly modulate Zn 2+ nucleation kinetics across temperatures, promoting uniform Zn deposition with progressively increasing grain sizes during prolonged cycling. Consequently, Zn||Zn cell showcases highly reversible plating/stripping exceeding 5300 cycles at 50 mA cm −2 , while exhibiting broad thermal tolerance across a wide temperature range of −40°C to 60°C.

We demonstrate how improved electrochemical performance can be achieved when using an ionomer free porous transport electrode (PTE) coupled with a traditional catalyst coated membrane (CCM) assembly in PEM water electrolyzers. Notably, we reveal that the superior performance achieved when utilizing a hybrid PTE and CCM assembly is due to enhanced ohmic performance caused by optimal contact with both the porous transport layer (PTL) and PEM interfaces. Using operando neutron radiography, we demonstrate that configurations utilizing a CCM resulted in more rapid water replenishment to reaction sites, indicating enhanced membrane hydration beneficial for performance. This enhanced membrane hydration coupled with improved contact area at the PEM‐catalyst layer (CL) and PTL‐CL interfaces was revealed through the reduced ohmic overpotentials of the hybrid PTE‐CCM design, which achieved the lowest ohmic overpotential of 431 mV at 2000 mA cm −2 . While the average in‐plane water distributions are generally similar between cell configurations, we reveal that utilizing a PTE configuration promotes a more homogenous water distribution near the CL‐membrane interface due to enhanced catalyst utilization.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"66 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768553","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 designed a series of Sr 2 Fe 1.35 Mo 0.45 Ni 0.2 O 6−δ (SFMN) with different levels of B‐site Fe/Ni defects and Vö. Cross‐scale experimental and theoretical results revealed that increased B‐site Fe/Ni defects and Vö strengthened Fe 3d−O 2p orbital hybridization, thereby enhancing electrical conductivity, but this trend reversed beyond a certain threshold. Then, in situ topotactic exsolution was performed for SFMN to refill B‐site cation defects while maintaining Vö concentration intact. The resulting sample without B‐site cation defects exhibited a faster oxygen‐ion transport capability than conventionally exsolved SFMN with rich B‐site defects, achieving a high current density of 2.40 A cm −2 at 1.5 V and 850°C, while avoiding SrCO 3 formation. Theoretical calculations demonstrated that refilling B‐site cation defects in exsolved SFMN thermodynamically accelerated CO 2 adsorption and activation, as well as suppressed Sr segregation.

To overcome the inherent lattice stress caused by Mg‐ion, we investigated a series of flexible organic molecules (FOMs), and for the first time proposed a novel ion‐adaptive strategy, achieving a high‐performance FOM with modulated molecular steric hindrance, high practical capacity, and robust stability in AMIBs. In contrast with ever‐increasing lattice stress with successive Mg‐ion intercalation in conventional electrode, the subsequent ion intercalation reduced the stress by facilitated ion‐storage in the optimized ion‐adaptive FOM, such as tribenzoquinoxaline‐5,10‐dione (3BQ), with ultimately improved practical capacity (332.1 mAh g −1 at 1.0 A g −1 ), ranking among the highest capacity in AMIBs to date. Furthermore, the expanded planar architecture confers enhanced cycling stability on the ion‐adaptive 3BQ, maintaining a high specific capacity of 196.7 mAh g −1 even after 7,000 cycles at 10.0 A g −1 .

Deep generative models can address slow experimental throughput and high computational costs of traditional microstructure resolution methods, yet most literature focuses on Generative Adversarial Networks, prone to mode collapse issues. This work applies a generative diffusion model to synthesize 3D‐resolved multiphase microstructures of lithium ion battery and proton exchange membrane fuel cell electrodes, sourced from experimental imaging and computer‐based simulations. Generated volumes are validated against training data based on microstructural descriptors, including volume fraction, specific surface area, and tortuosity factor. Moreover, the standard cubic sub‐volume augmentation strategy used forgenerative model training fails to capture depth‐dependent features in thick and heavily processed microstructures, such as calendered electrodes. A depth‐aware augmentation pipeline is proposed to incorporate full electrode thickness into training samples, improving through‐thickness tortuosity factor accuracy in the generated electrodes. Furthermore, 3D‐resolved multiphysics simulation on the generated microstructures reproduce the performance behavior of their training counterparts with high accuracy. These results establish a diffusion model‐based framework as a viable means to generate commercially relevant electrode data, intended for computational optimization and design of next‐generation energy devices.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"6 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2026-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148768556","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, a sea‐urchin‐like Co 4 N/Co 2 P composite is constructed via the in situ introduction of a second phase, where the induced interfacial strain and electronic modulation lead to the formation of high‐spin Co sites, and the composite is further applied as a modified separator. Due to the differences in crystal structure and electronic properties between Co 4 N and Co 2 P, their interfacial contact induces charge redistribution and lattice mismatch, which subsequently generate localized tensile and compressive strains, along with an asymmetric N─Co─P coordination environment, thereby modulating the local electronic structure of Co active sites. Theoretical calculation and in situ characterization confirmed that the synergistic effect of interfacial strain and electronic effects induces d‐orbital spin splitting and energy level rearrangement, increasing unpaired electrons and elevating the spin state of Co. The enhanced spin state strengthens d–p orbital hybridization with sulfur intermediates, accelerating charge transfer and optimizing adsorption behavior. Accordingly, the Co 4 N/Co 2 P‐modified separator battery delivers 1389.4 mAh g −1 at 0.2 C and retains 905.9 mAh g −1 after 100 cycles (0.35% decay per cycle).
