Abstract A vital approach to accessing high‐safety and high‐energy‐density lithium batteries is develop solid‐state electrolytes (SSEs) instead of liquid electrolytes. However, lithium‐ion transport interface stability issues puzzle the construction (SSLBs). Thus, developing fast‐ionic conductors with high electrochemical performances chemical crucial SSLBs. Nanowires (NWs) possess aspect ratios for maintaining carrier along radial direction, thus being extensively employed in SSLBs enhancement ion efficiency, mechanical properties, thermostability, flame retardancy, between electrodes electrolytes, consequently boosting cycle safety In this work, advances NWs SSLBs, from rational design synthesis strategies applications composite cathodes, anode materials, SSEs are systematically reviewed. The key role mechanism SSE performance by introducing concluded detail. Finally, existing challenges anticipated prospects future development advanced nanowire‐based summarized demonstrated. This review aims provide a comprehensive understanding facilitate application

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown
Published: April 29, 2025
Ionogels represent promising materials for thermoelectric generators that efficiently convert low-grade heat into electricity due to their flexibility, stability, nonvolatility, and high thermopower. However, improving performance presents challenges stemming from the complex interplay between ionic conductivity thermal conduction. In this study, we developed a highly oriented nanofibrous ionogel membrane through electrospinning of poly(ethylene oxide) (PEO) blended with linear CO2-derived polycarbonate oligomer an liquid, ethylmethylimidazolium dicyanamide. The liquid facilitated formation aligned nanofiber structures, which demonstrated superior reduced conduction compared bulk counterparts, primarily size effect inherent in nanofibers. Additionally, incorporation can increase amorphous region PEO matrix strengthen ion-polymer interaction without compromising orientation nanofibers thanks its compatibility abundance electron-withdrawing carbonate groups. This strategy effectively decouples conduction, thereby enhancing efficiency ionogels. advancement paves way development ionogels use flexible electronics energy harvesting applications.
