A.;Kucernak, Anthony R.;Jelfs, Kim E.;McKeown, Neil B.;Song, Qilei research published 《 Development of efficient aqueous organic redox flow batteries using ion-sieving sulfonated polymer membranes》, the research content is summarized as follows. Redox flow batteries using aqueous organic-based electrolytes are promising candidates for developing cost-effective grid-scale energy storage devices. However, a significant drawback of these batteries is the cross-mixing of active species through the membrane, which causes battery performance degradation To overcome this issue, here we report size-selective ion-exchange membranes prepared by sulfonation of a spirobifluorene-based microporous polymer and demonstrate their efficient ion sieving functions in flow batteries. The spirobifluorene unit allows control over the degree of sulfonation to optimize the transport of cations, while the microporous structure inhibits the crossover of organic mols. via mol. sieving. Furthermore, the enhanced membrane selectivity mitigates the crossover-induced capacity decay while maintaining good ionic conductivity for aqueous electrolyte solution at pH 9, where the redox-active organic mols. show long-term stability. We also prove the boosting effect of the membranes on the energy efficiency and peak power d. of the aqueous redox flow battery, which shows stable operation for about 120 h (i.e., 2100 charge-discharge cycles at 100 mA cm-2) in a laboratory-scale cell.
