Construction of hierarchical proton sieving-conductive channels in ...
In this work, the continuous hierarchical proton sieving-conductive channels are constructed in the ion conductive membranes through the strategy of grafting sulfated UIO-66 (UIO–66OSO3) along the polybenimidazole (PBI) backbones (Scheme 1).The sulfate ester group, with superior reactivity and acidity to the commonly used sulfonic acid group, …
Lithium ion conducting membranes for lithium-air batteries
In Li-air batteries with aqueous electrolytes (Figure 2 b and c), Li + conducting membranes becomes indispensable to separate the Li anodes and the aqueous electrolytes because the direct contact of H 2 O and Li can induce severe reactions even for a very short time.Polyplus Co., in 2004, introduced glassy ceramic membranes …

Ion-solvating membranes (ISMs) are non-porous polymer films that can uptake KOH and, therefore, conduct ions and be used as separators in electrolysers. Here the authors report an ISM for alkaline ...
Fast and Selective Ionic Transport: From Ion-Conducting Channels to Ion ...
This review discusses selective and fast transport of ionic species (ions and their associates) through systems as diverse as ion-conducting transmembrane proteins and ion exchange membranes (IEMs) in aqueous environments, with special emphasis on the role of electrostatics, specific chemical interactions, and morphology (steric effects). Contrary to …

Composite lithium-conductive LATP+PVdF membranes: …
The commercial porous (Celgard, Daramic), ion-exchange (Nafion, Neosepta), and glass-ceramic (LiCGC) membranes, if used in non-aqueous flow batteries, suffer from poor selectivity, low ionic conductivity, insufficient chemical stability, fragility, or a high price [17], which in some cases approaches up to 50% of the total battery cost [3].
Sulfonated para‐Polybenzimidazole Membranes for Use in …
Ion conducting membranes play a crucial role in redox flow batteries, separating anolyte and catholyte while allowing proton transport to complete the circuit. However, most membranes are trapped in a trade-off relation and show either low conductivity or high vanadium crossover.
