Bio-inspired ion channels for suppressing interfacial parasitic reactions and enabling low-energy ion desolvation in aqueous supercapacitors.

ABSTRACT: The sluggish de-solvation reaction kinetics of hydrated ions and the occurrence of undesired water electrolysis on the electrode-electrolyte interface pose significant challenges to the practical deployment of aqueous supercapacitors. Interestingly, biological ion channels exhibit remarkable abilities to facilitate the de-solvation and low-energy transport of hydrated ions, and these are achieved through their size-limited confinement effects and electrostatic interactions. Inspired by such transit mechanisms of ion channels, we propose an interesting strategy to facilitate the rapid desolvation of electrode surface ions with low-energy transport. This strategy utilizes the aperture confinement effect and charge effect of biological ion channels to construct porous carbon electrodes. Concr
