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...
Abstract Ion exchange membranes (IEMs) that can selectively transport ions are crucial to a variety of applications, such as ion extraction/separation, fuel cells, redox flow batteries, and water electrolysis. IEM performance, in terms membrane permeability/conductivity selectivity, relies heavily on the formation effective channels within membranes, there exists tradeoff between which obstructs development widespread adoption IEM‐based processes. To overcome this advance IEM‐related...
Ion exchange membranes allowing the passage of charge-carrying ions have established their critical role in water, environmental, and energy-relevant applications. The design strategies for high-performance ion evolved beyond creating microphase-separated membrane morphologies, which include advanced to ion-selective membranes. properties functions been repeatedly updated by emergence materials with subnanometer-sized pores understanding movement under confined micropore channels.

Viologen derivatives have been developed as negative electrolyte for neutral aqueous organic redox flow batteries (AOFBs), but the structure-performance relationship remains unclear. Here, it was investigated how structure of viologens impacts their electrochemical behavior and thereby battery performance, by taking hydroxylated examples. Calculations frontier molecular orbital energy configuration promise to be an effective tool in predicting potential, kinetics, stability, may broadly...
An ultramicroporous membrane provides highly selective ion transport, enabling power generation from solutions with/without salinity difference, or potentially wastewater. This extends the concept of extracting Gibbs energy solution mixing.
We propose and synthesize a multifunctional pentafluorophenyl phosphonated ionomeric binder of intrinsic microporosity, enabling high-power, low-Pt loading durable high-temperature fuel cells up to 240 °C.
Ion exchange membranes (IEMs) play a critical role in aqueous organic redox flow batteries (AORFBs). Traditional IEMs that feature microphase-separated microstructures are well-developed and easily available but suffer from the conductivity/selectivity tradeoff. The emerging charged microporous polymer show potential to overcome this tradeoff, yet their commercialization is still hindered by tedious syntheses demanding conditions. We herein combine advantages of these two types membrane...
2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) derivatives are typical catholytes in aqueous organic redox flow batteries (AORFBs), but reported lifetime of them is limited. We find that the increase Hirshfeld charge decreases Gibbs free energy change (ΔG) values side reactions TEMPO, a near-linear relationship, and then exacerbates their degradation. Here we predict synthesize TEMPO derivative, namely TPP-TEMPO, by analyzing charge. with smallest highest ΔG, an order magnitude more stable...
Bipyridinium derivatives represent the most extensively explored anolyte materials for pH-neutral aqueous organic redox flow batteries, and feature two separate electron-transfer steps that cause a sharp decrease in cell voltage during discharge. Here, we propose strategy to fulfill concurrent two-electron electrochemical reaction by designing extended bipyridinium (exBPs) with reduced energy difference between lowest unoccupied molecular orbital of exBPs β-highest occupied singly form. To...

Processable polymers of intrinsic microporosity (PIMs) are emerging as promising candidates for next-generation ion exchange membranes (IEMs). However, especially with high capacity (IEC), IEMs derived from PIMs suffer severe swelling, thus, resulting in decreased selectivity. To solve this problem, we report ultramicroporous polymer framework constructed rigid Tröger's Base network chains, which fabricated via an organic sol–gel process. These demonstrate excellent antiswelling, swelling...
