Mesoscale dynamics of electrosorbed ions in fast-charging carbon-based nanoporous electrodes

Abstract

Electrosorption, the accumulation of electrolyte ions at charged interfaces, is a common phenomenon across various electrochemical systems. Its impact is particularly pronounced in nanoporous electrodes owing to their high surface-to-volume ratios. Although electrosorption alters the ion distribution at the electrode–electrolyte interface through the formation of an electrical double layer, the effects of electrosorbed ions on the charge storage dynamics in nanoporous electrodes and their ability to improve charging processes have often been overlooked. Here we use a multilayered reduced graphene oxide-based membrane as a model nanoporous electrode material, integrating numerical simulations..
