A multi-physics abuse testing platform integrating mechanical, electrical, and thermal stimuli was developed to investigate the abuse tolerance of lithium-plated and normally aged batteries, based on their external physical responses and irreversible chemical reactions. Novel evaluation metrics for crush-induced failure were first established, including rebound rate, total absorbed energy of plastic deformation, and frequency of soft short-circuit events. The thermal runaway evolution during heating abuse was systematically analyzed by dividing the process into three stages based on voltage drop and characteristic temperature thresholds. For overcharge abuse, incremental capacity (IC), differential voltage (DV), differential temperature (DT), and differential mechanical stress (DM) curves were employed to qualitatively evaluate lithium-ion loss and active material degradation. Ten mechanical–electrical–thermal indicators were proposed to comprehensively assess battery failure under various abuse scenarios. The results demonstrate that the mechanical stability of fresh, normally aged, and lithium-plated batteries sequentially decreases during crush testing (maximum failure displacement reduced by 8.6%). Thermal tolerance during heating abuse exhibits a negative correlation with state of health (SOH), with lithium-plated batteries showing the poorest performance (average venting time advanced by 26.8%). In overcharge abuse, venting time positively correlates with SOH, accompanied by a 34.9% surge in heat generation during the smoking phase. Integrated analysis of electrochemical–thermal stability and failure metrics reveals that lithium-plated batteries pose the highest safety risks across all abuse conditions, necessitating prioritized attention in intelligent battery management systems (BMS) for early risk warning and timely replacement. These findings provide critical insights for optimizing safety design and operational strategies of lithium-ion batteries in practical applications.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"27 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144756425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, temperature fluctuations and flammability significantly impact PV system efficiency and lifespan, necessitating effective temperature management and flame retardancy. In this study, we introduced an innovative environmentally friendly backsheet for solar modules, combining radiative cooling with phase change materials (PCMs) to achieve superior thermal regulation and fire resistance. Functionalized boron nitride nanosheets (BNNs) were prepared <em>via</em> ionic liquid-assisted ball milling. The biomass-derived diatomaceous earth (DE) and BNNs were then bonded with polyvinyl alcohol (PVA) and freeze-dried to fabricate aerogels. The final DE/BNN phase change materials (PCMs) obtained from vacuum impregnation with methyl stearate (MS) exhibited high thermal conductivity (0.778–1.311 W m<small>⁻¹</small> K<small>⁻¹</small>), high latent heat (92.7–126.1 J g<small>⁻¹</small>), and flame-retardant properties (total heat and smoke release were reduced by 32.6% and 60.0%). When applied as a backsheet to single-crystal silicon (sc-Si) solar cells, the DE/15BNN PCM significantly reduced the operating temperature by 6.7 °C and enhanced the power conversion efficiency (PCE) by 9.3%. Benefiting from the inherent properties of the matrix and the effective restriction of electron movement by BNNs, the DE/BNN PCM achieved high insulation properties (22.22 kV mm<small>⁻¹</small>), meeting the standards for commercial backsheets. Additionally, the DE/BNN PCM demonstrated excellent UV resistance, maintaining its performance even after prolonged UV exposure.

Nevertheless, dual-atom catalysts (DACs) can prospectively address these concerns, given their adaptability to various substrates, maximized atomic utilization efficiency, and distinct electronic structure characteristics. Overall, this review explores recent DACbased advancements, predominately focusing on morphology coupled with atomic coordination, electronic structure combined with redox kinetics, and battery performance. The underlying atomistic mechanisms determining DAC activity are highlighted, encouraging further investigation via computational and experimental approaches. How composition affects experimental properties – including charge transfer, bonding, and property tuning – is edif ied via correlations developed through theoretical frameworks. Across these considerations, how integration of DACs with variedcompositions and morphological characteristics – as well as thermodynamic, kinetic, and electronicproperties – synergistically impact batteries is emphasized.

Direct recycling including direct regeneration and direct upcycling offers promising closed-loop solutions specifically tailored to address these intricate structural and chemical changes. Regeneration restores original performance, while upcycling enhances properties through methods like compositional tuning, morphological control, doping, and surface engineering. This review uniquely contextualizes recent advances in the direct recycling of NRLO by linking degradation analysis with recovery strategies.

Herein, we propose a facile low-temperature etching strategy to construct cadmium-doped NiFe-layered double hydroxide (NiFeCd-LDH) nanosheet arrays on nickel foam (NF) as a highly efficient and corrosion-resistant anode. The optimized NiFeCd-LDH/NF demonstrates exceptional oxygen evolution reaction (OER) activity in alkaline simulated seawater, achieving an ultralow overpotential of 337 mV at 1000 mA cm-2, while maintaining robust stability under saline conditions (0.5 M NaCl). When integrated into an anion exchange membrane (AEM) electrolyzer with a Pt/C/NF cathode, the full cell requires only 1.84 V to deliver 500 mA cm-2 in a 6 M KOH and 0.5 M NaCl solution at 80℃, with negligible performance decay over 50 h. Systematic investigations reveal that the enhanced chloride tolerance originates from the cadmium-induced electronic modulation, which suppresses ClER kinetics and stabilizes the active metal sites. Furthermore, dynamic parameter optimization (temperature, electrolyte concentration, and current response) significantly reduces cell voltage and improves energy conversion efficiency.

Surface point defect concentrations strongly depend on the oxygen stoichiometry in the bulk and the gas phase's chemical composition (e.g., oxygen activity). However, many chemically sensitive surface analysis techniques rely on UHV conditions, leading to a two-fold deviation from surfaces under operational conditions. On the one hand, adsorbed gas phase species are missing in UHV. On the other hand, transition metal oxidation states and the oxygen vacancy concentration at surfaces are connected to the oxygen stoichiometry in the bulk of the material, which is inevitably altered during cell transfer from electrochemical measurement to UHV-based analytics. To reduce this two-fold gap between analytical studies and typical operation conditions, we present a novel solid oxide cell design for electrochemical oxygen activity control of surfaces in UHV-based analytic tools. Its key feature is an oxygen-ion buffering counter electrode containing a Fe|FeO phase equilibrium with known oxygen activity. A defined voltage between this counter electrode and the oxide under investigation (used as working electrode) defines the oxygen activity of the relevant oxide surface. Moreover, simultaneous thin film coulometry allows the determination of the bulk oxygen deficiency in the respective oxides. As a proof of concept, we use UHV-based XPS to compare the bulk and surface reducibility of fluorite-type Gd-doped ceria and perovskite-type Fe-doped SrTiO<small>₃</small> under electrochemical oxygen activity control.

However, current hydrogel materials face critical challenges in artificial ligament applications, including insufficient strength, poor fatigue resistance, and the lack of real-time health monitoring capabilities, which severely limit their clinical use. Herein, a simple strategy for synergistically enhancing the mechanical strength of hydrogels through wet annealing and solvent exchange was developed. Wet annealing initially promotes the formation and growth of crystalline domains, while subsequent gradient solvent exchange with a deep eutectic solvent (DES) strengthens intermolecular interactions, inducing further growth of crystalline domains. As a result, a hydrogel (WE-PVA) with a high density of crystalline domains was constructed. Interestingly, WE-PVA exhibits excellent tensile strength (7.8 MPa), outstanding fatigue resistance (Γ = 4210 J·m-²), and long-term stability, highlighting its great potential for practical applications in artificial ligaments. Moreover, WE-PVA demonstrates remarkable sensing capabilities, enabling real-time monitoring of ligament status, further enhancing its functional value. This strategy provides a simple and versatile approach for designing hydrogels with both high strength and fatigue threshold, and holds significant promise for applications requiring superior mechanical performance.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"1 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
