The electrolyte plays a pivotal role among the critical components of LMBs. However, traditional organic electrolytes pose significant safety risks and shorten battery life due to their electrochemical instability, volatility, and flammability. Alternatively, ionic liquids (ILs), composed of anions and cations, are room-temperature molten salts characterized by ultra-low volatility, high ionic conductivity, excellent thermal stability, low flammability, and wide electrochemical windows. Based on these properties, liquid IL electrolytes (ILEs) and polymeric IL electrolytes (PILEs) have shown immense potential in enhancing battery cycle stability, energy density, lifespan, and safety. This review aims to comprehensively explore and summarize recent applications of ILEs and PILEs in LMBs, including their use as liquid and solid-state electrolytes, as well as ILs serving as film-forming additives, interfacial wetting agents, and pretreatment reagents. Additionally, the review delves into the solvation structures of Li+ ions within different IL-based electrolytes and the resulting interfacial chemical characteristics. Finally, based on literature reports and our previous work, we identify current challenges and propose solutions for the future application of IL-based electrolytes in LMBs.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142580717","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}

This study introduces a sustainable cross-linked poly(castor oil-co-δ-valerolactone) cyclohexyl urethane (PCVU) substrate for flexible, stretchable transparent conducting electrodes (TCEs) based strain sensors and heaters. PCVU is synthesized as a highly transparent (>90%), stretchable (>190%), and thermally stable (~210°C) substrate via thermal cross-link polymerization of poly(castor oil-co-δ-valerolactone) triol and 4,4′-methylenebis(cyclohexyl isocyanate) on a glass mold. PCVU exhibits good chemical stability in various organic solvents and degrades completely in 72 days in an alkaline medium (pH = 14). Using PCVU, we fabricated a robust, flexible, and stretchable TCE with low sheet resistance (<50 Ω sq-1). The TCE fabrication process includes applying an electrospun polyvinyl alcohol (PVA) layer as a leveling agent to improve the adhesion of silver nanowires (AgNW) and utilizing a heat-based nano-welding technique to enhance durability and mechanical stability. The TCE-based strain sensor showed stable and repeatable resistance changes (ΔR/R0) under 5-15% strains, with fast response and consistent signal stability over 100 cycles at 5% strain. The flexible heater reached a maximum temperature of ~150°C at 5.5V, with rapid heating and cooling responses (15 s each). Practical applications include a strain sensor for real-time monitoring of human motion (finger, wrist, elbow, and neck flexion) and a heater used as a thermotherapy pad for the wrist and finger, demonstrating the potential of PCVU-based TCEs for wearable and medical devices.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":null,"pages":null},"PeriodicalIF":11.9,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588617","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}

This work constructs a self-supported catalytic electrode (Pt-NiB@NF) by growing boron-based catalytic materials in situ on nickel foam (NF) through mild electroless plating, and then rapidly “decorating” trace amounts of platinum (Pt) on the precursor surface via electrodeposition. The trace amounts of Pt (0.49 wt%) decoration achieves a 3.5-fold enhancement in the performance of NiB@NF. Pt-NiB@NF exhibits lowly hydrogen evolution reaction (HER) overpotentials of 70 mV and 12 mV at a current density of 100 mA cm-2 in neutral high-salt media and alkaline environments, respectively. Meantime, Pt-NiB@NF demonstrates long-term stability at industrial-scale current densities, maintaining for 120 hours at 100 mA cm-2 in neutral high-salt media and for 1200 hours at 500 mA cm-2 in alkaline electrolyte. The strategy of mild electroless plating and rapid electroplating realizes large-area electrode preparation for assembling proton exchange membrane electrolyzer, more promising for industry-grade hydrogen production via water splitting.

The AP (CNT-0.02) is identified as the best performer with the highest mineralization rate for formaldehyde (FA) by efficiently harnessing the intrinsic redox capabilities of each n-type semiconductor through the formation of an internal electric field at their interface. The superiority of AP (CNT-0.02) is validated in terms of clean air delivery rate [CADR] of 13.3 L min<small>⁻¹</small> and quantum yield [QY] of 2.74 × 10<small>⁻³</small> molecules photon<small>⁻¹</small> against 5 ppm FA in dry air under low UV-A LED (1 W) light irradiation conditions. Its remarkable stability (<em>e.g.</em>, over 5 reuse cycles) even at high FA levels (<em>e.g.</em>, at 100 ppm) may also come from the synergistic adsorption-photocatalysis of FA molecules through the S-scheme charge transfer pathway to efficiently preserve their reactive intermediates.

In this study, a simple method for passivating the SnO2 by integrating Carboxymethyldextran Sodium (CMD) into the SnO2 colloidal mixture was presented. It is shown that the addition of CMD can improve the electronic property of SnO2, reduce the nonradiative recombination, effectively passivate the defects at the buried interface of SnO2 and perovskite, and make the device form a suitable energy level arrangement.
