Charged two-dimensional nanochannels with high ion density enabling ultrafast monovalent and multivalent ion conductivity.

ABSTRACT: Ion conductors with fast ion transport and reliable stability are highly desired for energy storage and conversion devices. While solid-state ion conductors with high safety and energy density are promising materials for a new generation of electrochemical devices, it remains challenging to achieve high ion conductivity, especially for multivalent ions due to the stronger steric effect and electrostatic interactions. Here, we report the well-ordered charged nanochannels with high ion density, typically fabricated by stacking montmorillonite (MMT) nanosheets, to serve as versatile solid-state ion conductors. Characterization studies and molecular dynamics simulations reveal that the "adaptive" nanochannel height of MMT membranes, combined with Coulomb interaction-induced concerted ion movem
