While high‐entropy oxides (HEOs) show catalytic promise, conventional methods predominantly focus on elemental regulation and neglect critical morphological optimization, thus failing to unify composition‐architecture‐transport functionality to prevail at industrial conditions. Here, the morphological HEO electrode is introduced, a bioinspired framework integrating multielement mixing, architectural hierarchy, and surface adaptation. High‐throughput optimization identifies a critical nanosecond laser parameter window where rapid quenching traps metastable FeCoNiMoCrOx HEO nanoparticles foliage while Marangoni flows sculpt Ti microcone trunks. This structure exhibits superaerophobic‐superhydrophilic properties and exceptional oxygen evolution performance (η10 = 188 mV). In an anion‐exchange membrane electrolyzer, the electrode achieves 1 A cm−2 at 1.82 V (surpassing commercial IrO2‐coated Ti mesh), while maintaining stable operation for 600 h at 500 mA cm−2 (degradation rate: 38.33 µV h−1). DFT calculations confirm that Mo/Cr electronically modulates the primary OER active Ni sites via the M‐O‐M network, optimizing the d‐band center and favoring the Adsorbate Evolution Mechanism (AEM). This work establishes a paradigm for industrial electrocatalysts by encoding compositional complexity, structural coherence, and interfacial adaptability through morphological design, where multifunctionality emerges from multiscale synergy rather than isolated optimization.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"39 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145093620","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 three-dimensional carbon frameworks can regulate ion flux to mitigate dendrite formation, current designs usually lack the protective interfacial layers, triggering electrolyte parasitic reactions during Na plating. Moreover, their uniformity and excessive thickness promote top-down Na-deposition, which thus reduces spatial utilization, especially under high current densities and deep cycling. Herein, a thickness-tunable (5–30 µm) multi-functional carbon film, which seamlessly integrated a protective interfacial layer with gradient sodiophilic hosts (PL/GS-CF), is engineered to concurrently regulate desolvation and Na-deposition. Mechanistic studies revealed that the top protective layer, with size-tunable micropores and large carbon interlayer space, created graded sieving pathways (DME→PF6−→Na+) for the rapid step-by-step desolvation, spatially decoupling electrolyte decomposition from Na deposition to enable the stable SEI formation and fast Na+ transfer kinetics. The host units with gradient sodiophilic/dense sites and subcritical nucleation dimensions facilitated the “bottom-up” layer-by-layer Na-plating, therefore enhancing carbon volumetric-utilization and sodium reversibility. The PL/GS-CF@Na symmetric cells realized a competitive-long life of 700 h with an ultra-high reversible volumetric capacity of 1120.4 mAh cm−3 at a depth of discharge (DOD) of 100% and a current density of 12 mA cm−2.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"77 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084049","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}

As one of the most crucial components in ASSSBs, solid electrolytes (SEs) feature acceptable ionic conduction, high safety, and wide electrochemical window. Particularly, sodium rare earth silicate (Na5RESi4O12) is a new class of SEs with high ionic conductivity (10−3 S cm−1) at room temperature, low synthesis temperature (900−1100 °C), and excellent chemical stability. In Na5RESi4O12, rare earth cations (e.g., Sm, Gd, Y, In) can occupy the position of RE, which enables huge potential on the regulation of physicochemical properties, facilitating the achievement of high-performance SEs. Here, fundamental features, crystal structure, ionic transport mechanism, synthesis routes, and electrochemical performance of Na5RESi4O12 SEs are systematically overviewed. To tackle the interfacial issues that hinder the stable operation of ASSSBs, several effective strategies are summarized and discussed.

However, global industrial and agricultural activities have severely disrupted natural nitrogen cycling, causing environmental impact and energy consumption through conventional processes such as the Haber–Bosch and Ostwald method. Addressing this imbalance requires innovative technologies that reconcile efficient nitrogen utilization with environmental sustainability. Electrochemical nitrogen transformation, especially the electrochemical oxidation of ammonia under mild conditions, has emerged as a promising solution, enabling the conversion of reactive nitrogen species into energy and valuable products while mitigating environmental impacts. This review comprehensively examines recent advances in ammonia-centric nitrogen utilization technologies, focusing on their roles as: 1) carbon-neutral energy vectors (ammonia fuel cells), 2) efficient hydrogen carriers (ammonia cracking), and 3) precursors for high-value nitrogenous chemicals via controlled oxidation pathways under mild conditions. The full-chain design framework, namely, from material innovations to practical system integration, is analyzed, while elucidating fundamental reaction mechanisms, performance benchmarks, and scale-up methodologies. The review aims to provide a foundational reference for developing sustainable electrochemical solutions for establishing a nitrogen-based and net-zero energy/resource economics, and in the meantime, addressing the potential nitrogen pollution control and resource recovery.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"38 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084075","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 study, a structural capsule architecture of ultrasmall O-HEA nanocrystals composed of Pt, Co, Ni, Fe, and Cu uniformly confined by few-layered graphene (PCFNC@Gr) is rationally designed. The PCFNC@Gr exhibits remarkable catalytic performance for both hydrogen evolution and oxygen evolution reaction (HER and OER) with required overpotentials of 52.1 and 280 mV, respectively, at a current density of 10 mA cm−2, and demonstrates excellent long-term stability in alkaline medium.

This application calls for both high thermoelectric performance and superior mechanical properties to ensure decent deformability and processibility, which is nonetheless largely overlooked. In this work, the excellent temperature-induced plasticity of Bi0.85Sb0.15 as the classic liquid-nitrogen-temperature thermoelectric material is reported. The material shows large compressive strains exceeding 60% above ≈423 K, as well as a decent compressive strain of ≈21.5% at room temperature. By microstructural and atomistic analyses, the plasticity at slightly elevated temperature is ascribed mainly to the grain elongation and reorientation, which is rooted in the thermally amplified atomic vibration and thus reduced slip barrier energy. The low brittle-to-ductile transition temperature allows the material to be warm-processed into desired shapes in a metal-like manner with high efficiency and low losses. Particularly, the warm-extruded Bi0.85Sb0.15 shows comparably high thermoelectric performance as well as larger strength and compressibility as compared to the original bulks. These findings enable warm metalworking to promote the development of miniaturized and hetero-shaped thermoelectric cooling techniques around liquid nitrogen temperature.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"79 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145084051","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 innovative z-axis non-coplanar architecture of functional layers enables synergistic chloride resistance via physical blocking (MnO2 barrier) and electrostatic repulsion (CO32− interlayers).
