https://phys.org/news/2023-04-membrane-near-frictionless-ion.html

"CO2 electrolyzers, water electrolyzers, fuel cells, redox flow batteries and ion-capture electrodialysis... screen out specific substances to prevent crossover; efficiently conducting specific ions... triazine framework polymer membrane break conductivity-selectivity trade-off... anti-swelling and anti-aging, low swelling ratio water absorption, rigid channels ensured high selectivity from size-sieving enabling low permeability... neat area-specific resistance 0.17 Ω cm2, extreme densities from 200 to 500 mA cm-2"
