This study presents a novel composited insulation material that integrates nanofiber aerogel, particle aerogel, and robust microspheres to effectively mitigate TRP. Flexible mullite nanofibers (MNFs) are synthesized via a sol-gel method combined with electrospinning, with systematic investigations of the effects of aluminum-silicon ratio, spinning parameters, and polymer concentration on their properties. The resulting MNF mats exhibit ultralow thermal conductivity (0.0241 W/(m·K)) and exceptional thermal stability (-196°C to 1300°C). To further enhance the composite properties, hollow glass microspheres provide a robust mechanical support framework, achieving a compressive strength of 1.45 MPa, while specially modified aerogel particles significantly improve thermal insulation performance. Results show that increasing MNF content enhances mechanical strength and initially improves but later reduces thermal insulation performance. Tests on battery modules reveal that a 1 mm thick insulation material extends the average TRP time from 48.5 s to 1046 s, reducing the heat transferred to the adjacent battery from 198.34 kJ to 85.52 kJ. Remarkably, a 2 mm thick insulation layer completely blocks TRP, achieving a maximum temperature differential of 634.2°C between the front and back batteries while lowering heat transfer to 59.71 kJ. This study overcomes the longstanding trade-off between mechanical performance and thermal insulation in conventional materials, presenting a scalable and effective design strategy for advanced insulation materials with broad application potential in LIBs.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"53 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486414","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 high−entropy−induced dipole moment enhancement strategy is proposed to address the problems related to complex temperature variations. In particular, a new platform corresponding to liquid-liquid conversion appears at low temperatures, considered as another rate-determining step. High−entropy oxide La_0.71Sr_0.29(Fe_0.19Co_0.20Ni_0.20Zn_0.19Mn_0.22)O_3−δ (HE−LSMO) nanosheets are synthesized by incorporating more metallic ions into LaSrMnO₃, which would increase the crystal asymmetry, create the redistribution of the electron cloud in the HE−LSMO, thereby enhancing dipole moments and strengthening the dipole−dipole interaction between HE−LSMOs and polar intermediate lithium polysulfides (LiPSs). The HE−LSMO can effectively adsorb LiPSs and greatly promote rapid conversions of LiPSs during the sulfur reduction process at a range of −35 to 50°C. At 50°C, the S/HE−LSMO cathode exhibits a high initial specific capacity of 1455.9 mAh g⁻¹ at 0.5 C, with a capacity retention rate of 71.1 % after 100 cycles. At −35°C, the S/HE−LSMO cathode maintains an initial capacity of 740.7 mAh g⁻¹ at 0.5 C, with an impressive capacity retention of 90.4 % after 100 cycles. This work demonstrates the feasibility of the high−entropy−induced dipole moment enhancement strategy for lithium−sulfur batteries under wide temperatures.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"39 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486412","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}

Traditional battery designs and fabrication strategy fail to meet these comprehensive requirements, particularly in terms of flexibility and customizability for multi-bipolar battery integration. Herein, we demonstrate the large-scale screen-printing production of planar monolithically integrated solid-state lithium ion MBs (LIMBs), with key characteristics of superior areal capacity, excellent output voltage, and exceptional flexibility. The resulting individual LIMB delivers ultrahigh areal capacity of 1431 μAh cm^-2, ultralong cyclability without obvious capacity loss after 8000 cycles, and excellent dimensional customizability. Attributing to the flexibility of all components, especially solid-state electrolyte, together its strong interfaces with cathode and anode, our solid-state LIMBs demonstrate exceptional mechanical flexibility, without performance degradation after repeated bending. Moreover, we constructed an integrated energy-storage module consisting of five bipolar LIMB devices, which significantly boosts the output voltage to 12.5 V and maintains exceptional flexibility, thanks to its uniqueness of coplanar design and precise spacing arrangement. Our integrated LIMBs function as a flexible watchband, providing uninterrupted power to a wristwatch.

Techniques used to synthesize 0D, 1D, 2D, and 3D NeCMs and the atomic-level properties that influence their performance are described in relation to their dimensionality. The interactions that occur between NeCMs and PCMs, which are critical for multifunctionality of PCM composites, are also discussed. As a core objective, this review examines how the synthesis approaches for PCM-NeCM composites and their resulting morphological characteristics influence their thermal conductivity and photothermal efficiency. Phonon manipulation, localized heating, localized surface plasmon resonance, and interfacial thermal resistance (ITR) are identified as the key mechanisms that enhance thermal conduction and photothermal conversion of PCMs with the integration of NeCMs. Recent advancements are also highlighted to demonstrate the potential of these composites to optimize PCM technology for high-efficiency, multifunctional applications.

However, limited research has been conducted on how calendar aging influences subsequent cycling performance. This study addresses the gap by examining the effects of State-of-Charge (SoC) during short-term low-temperature storage on both calendar aging and cycling degradation in LIBs with high-nickel cathodes. The findings demonstrate that high SoC storage accelerates calendar aging by causing structural degradation at the cathode-electrolyte interface (CEI), leading to phase transitions and increased mechanical stress. However, these conditions also enhance cycling stability by promoting surface reconstruction of the high-nickel cathode, which reduces lattice strain and mitigates detrimental phase transformations. The surface reconstruction improves lithium-ion diffusion and stabilizes the crystal structure, resulting in less mechanical degradation during cycling. Conversely, low SoC storage leads to reduced structural degradation during calendar aging, but the lack of an inert protective layer on the cathode surface causes lattice strain and phase transitions during lithium intercalation, resulting in microcracks that compromise the cathode structure. Concurrently, transition metal dissolution, migration, and deposition accelerate anode degradation by promoting interfacial reactions, which exacerbate solid electrolyte interphase (SEI) formation and degradation, and consume reversible lithium ions. Storage is a critical process in the lifecycle of LIBs in electric vehicles (EVs), necessitating the development of advanced battery management strategies tailored to the SoC-dependent stabilities of active materials. These results emphasize the complex relationship between calendar and cycling aging, providing important insights into optimizing high-energy-density cathodes with long durability.","PeriodicalId":306,"journal":{"name":"Energy Storage Materials","volume":"22 1","pages":""},"PeriodicalIF":20.4,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143477705","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}
