Resumen de: WO2025103503A1
The subject invention pertains to sulfone-based hydrocarbon membranes with decentralized ion transport channels and carbon coating to obtain many small ion-transport channels to mitigate polysulfide crossover without sacrificing ionic conductivity. The developed sulfone-based membrane showed a higher ion selectivity and higher ion conductivity at a fraction of cost ($12 m-2) compared to the commercial fluorinated Nafion. The low-cost membranes enabled full polysulfide-ferrocyanide redox flow batteries with a high coulombic efficiency (＞99.9%), energy efficiency (>75%) and a low capacity decay rate (0.0027%per day) for 1600 cycles (> 6 months) at 20 mA cm-2. Embodiments have been shown to address the crossover bottleneck of polysulfide-based RFBs, remove the dependency on expensive fluorinated Nafion membrane, and provide opportunities for beneficial commercialization.
