Abstract Redox‐active covalent organic frameworks (COFs) with metal binding sites are increasingly recognized for developing cost‐effective, eco‐friendly electrodes in rechargeable energy storage devices. Here, we report a microwave‐assisted synthesis and characterization of triazine‐based polyimide COF that features dual redox‐active (−C=O from pyromellitic −C=N− triazine) COF@CNT nanocomposites ( COF@CNT‐X , where X=10, 30, 50 wt % NH 2 ‐MWCNT) formed through linking amino‐functionalized multiwalled carbon nanotubes. These composites evaluated as cathode materials the sodium‐ion batteries (SIBs). The amine functionalization renders bond between CNT, improving electronic conductivity, structural rigidity, long‐term stability. interfacial growth layers on CNTs increases accessible sites, enhancing sodium diffusion kinetics during sodiation/desodiation. COF@CNT‐50 composite exhibits outstanding Na + ion performance (reversible capacity 164.3 mAh g −1 at 25 mA ) excellent stability over 1000 cycles ambient temperature. At elevated temperature (65 °C), it also maintains good cycle Ex situ XPS analysis confirms importance active mechanism. Density functional theory (DFT) calculations reveal insights into corresponding energies structure, elucidating experimental voltage profile.

Solubility Challenges and Strategies for Organic Sodium‐Ion Batteries: Status and Perspectives

Small, Год журнала: 2025, Номер unknown

Опубликована: Фев. 24, 2025

Organic sodium-ion batteries (OSIBs) possessing excellent characteristics of low price, abundant sources, and eco-compatibility have gained numerous attentions in the recent decade. However, solubility is one main severe limitations application OSIBs, especially for small organic molecules. The dissolution molecules into electrolytes can cause loss active materials, pulverization electrodes, even short circuits batteries, as materials may shuttle through separators, thus leading to poor cycling stability batteries. Thus, there an urgent need develop insoluble OSIBs. advanced development OSIBs over past decades overviewed, primary challenges faced by long-cycling terms are systematically analyzed. Focusing on three core components battery system electrolytes, targeted optimization strategies proposed mitigate issues enhance performance. In addition, prospects toward long-cycle practical explored.
