Ultrathin Membrane With Ion‐Specific Gating Enables Interfacial Decoupling of Conductivity–Selectivity for Aqueous Flow Batteries

Angewandte Chemie, EarlyView.
An interfacial ion‐specific gating strategy shifts membrane design from ion diffusion within ion‐exchange channels to ion partitioning at the membrane–electrolyte interface, thereby decoupling selectivity from conductivity. The strategy underscores the pivotal yet underexplored role of the membrane–electrolyte interface, providing a broadly applicable ...
