With this approach, achieving high‐quality of lead iodide (PbI2) films during the initial stage is paramount to ensuring the overall performance and stability of the devices. However, during the ambient fabrication of PbI2, the residual high boiling point and hygroscopic dimethyl sulfoxide (DMSO) solvent significantly compromises the resulting film quality. Here, L‐Homoarginine hydrochloride (HargCl) is introduced into the PbI2 precursor solution, which greatly reduced the residual amount of PbI2·xDMSO and passivated the internal defects of perovskite (PVK) films. By leveraging this strategy, inverted perovskite solar cells entirely in the air are successfully prepared, achieving an impressive power conversion efficiency (PCE) of 25.05% — the highest reported efficiency to date for two‐step fully air‐processed inverted PSCs.

However, the harsh working conditions, especially the strong reductive acidic electrolyte-catalyst interface, make non-noble metal-based cathodes unsuitable for PEM electrolyzer. Here, a scale-up application of F modified CoP (CoP|F) cathode is demonstrated from 0.2 cm2 lab-scale three-electrode setup to a commercial 38 cm2 PEM electrolyzer. The operando X-ray absorption spectroscopy (XAS) and Raman results confirm that F modification can promote the breakage of Co─P bonds, reconstructed to amorphous metallic Co as true HER active sites. Density functional theory (DFT) calculations reveal that the presence of F in the CoP1-x lattice would lead to a more facile formation of P-vacancy under HER conditions, leading to more active zerovalent Co active sites for HER. This reconstructed surface shows high activity and tolerance in the reductive acidic electrolyte-catalyst interface. When used as a cathode in a commercial PEM electrolyzer, its performance is comparable to the state-of-the-art Pt/C catalyst, with a calculated hydrogen cost to be 2.17 $ kgH2−1.

In practical applications, batteries often experience extended resting periods at high charge levels after being fully charged. However, most studies focus on continuous cycling without considering intermittent resting, which can lead to flawed failure analysis and hinder optimization of Ni-rich cathode batteries. This study explores the degradation mechanisms of Ni-rich cathode full-cells subjected to intermittent resting after charging, revealing that Ni-rich cathodes undergo nonsteady-state structure transitions and chemical changes during high charge rest periods. The findings show that intermittent resting intensifies interfacial cracking within secondary particles due to coupled structure transitions and interfacial reactions, degrading lithium transport kinetics and creating lithium concentration gradients at multiple scales. Prolonged high anisotropy from delayed delithiation in the central region of primary particles, combined with surface-related multiple heterogeneous pinning effects, induces further intracrystalline damage. This damage is repeatedly reset and activated during intermittent resting, worsening mechanical degradation. These insights into the degradation pathways of Ni-rich cathodes provide a foundation for designing more durable materials and battery architectures to enhance the performance and longevity of lithium-ion batteries in practical applications.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"22 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143767141","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 evidence of facile lattice substitution further provides a key strategy for activating redox reaction centers and enhancing the cycling performance of such materials. Here, the study explores how Sn-mediated local atomic ordering enhances reversible anionic redox activity in Li1.3Mn0.4Nb0.3O2 through the use of aberration-corrected scanning transmission electron microscopy, ex/in situ X-ray techniques, and theoretical calculation. The results demonstrate that Sn incorporation optimizes the local atomic structure, fostering the formation of rapid Li+ diffusion “elevator” pathways and short-range ordered structures, thereby enhancing the Li+ transport network. Additionally, quantitative analysis of the redox pathways and degree of participation for Mn and O during charge–discharge cycles reveals that the Sn-mediated electrode exhibits enhanced anionic O redox activity at high charging voltages, maintaining elevated activity throughout subsequent cycling. This sustained performance not only indicates increased redox capabilities but also suggests improved structural stability. By elucidating the complex interplay between composition, local structure, and performance, this study advances the understanding of DRX materials and underscores the potential of strategic elemental substitution for optimizing disordered cathode materials in next-generation energy storage systems.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"22 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758524","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}

Utilizing water-based electrolytes, ZIBs eliminate fire risks and thermal runaway concerns, making them ideal for large-scale energy storage systems. The high theoretical capacity, low cost, high abundance, and low toxicity of zinc further enhance its suitability for grid-scale applications. However, conventional current collectors such as graphite foil exhibit limitations in scalability and mechanical properties, which make them unsuitable for industrial roll-to-roll manufacturing processes. This study addresses these limitations by exploring graphene-coated stainless steel foil as an alternative current collector. Here, graphene coating followed by heat treatment to remove the surface oxides improves the conductivity and corrosion resistance of the material. As a result, the fabricated ZIB exhibits high specific capacities of 1.90 and 0.91 mAh cm−2 at current densities of 0.3 and 2.0 C, respectively, and demonstrate a remarkable long cycle life with a capacity retention of 88.7% for up to 1500 cycles at a current density of 1.0 C, despite a high electrode loading of 13.27 mg cm−2.

This study introduces a novel, cost-effective, and scalable electrode delamination technique, termed “ice-stripping,” which employs sub-zero freezing to achieve near-complete (>90%) recovery of electrode coatings. Water is sprayed onto the electrode surface and placed on a sub-zero surface; the water freezes, forming a strong interfacial bond of the electrode coating to the cold plate. This enables the current collector to be stripped away from the electrode due to the stronger adhesion of the electrode to the plate. Unlike conventional thermal or chemical delamination methods, ice-stripping minimizes energy consumption, eliminates hazardous chemicals, and preserves the morphology and integrity of reclaimed materials. The technique is successfully applied to scrap and end-of-life lithium-ion and sodium-ion battery electrodes with various binder systems. Case studies focus on the recovery efficiencies and potential for direct recycling of Prussian white and hard carbon electrodes, graphite from end-of-life cells, and cathode and anode manufacturing scrap. Scalability and integration are also discussed.
