Membranes which allow fast and selective transport of protons cations are required for a wide range electrochemical energy conversion storage devices, such as proton-exchange membrane (PEM) fuel cells (PEMFCs) redox flow batteries (RFBs). Herein we report new approach to designing solution-processable ion-selective polymer membranes with both intrinsic microporosity ion-conductive functionality. Polymers synthesized rigid contorted backbones, incorporate hydrophobic fluorinated hydrophilic...
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 is the cross-mixing active species through membrane, which causes battery performance degradation.

Redox flow batteries (RFBs) have great potential for long-duration grid-scale energy storage. Ion-conducting membranes are a crucial component in RFBs, allowing charge-carrying ions to transport while preventing the cross-mixing of redox couples.
