2D CdPS₃-based versatile superionic conductors.

ABSTRACT: Ion transport in nanochannels is crucial for applications in life science, filtration, and energy storage. However, multivalent ion transport is more difficult than the monovalent analogues due to the steric effect and stronger interactions with channel walls, and the ion mobility decreases significantly as temperature decreases. Although many kinds of solid ionic conductors (SICs) have been developed, they can attain practically useful conductivities (0.01 S cm^-1) only for monovalent ions above 0 °C. Here, we report a class of versatile superionic conductors, monolayer CdPS₃ nanosheets-based membranes intercalated with diverse cations with a high density up to ∼2 nm^-2. They exhibit unexpectedly similar superhigh ion conductivities for monovalent (K^+</
