Key Points

To explore the role of phonon-ion interactions in enhancing ionic conduction in solid electrolytes.
Utilized theoretical models and experimental approaches to analyze phonon-ion interactions.
Measured ionic conduction rates in solid electrolytes under varying conditions.
Evaluated the correlation between phonon vibrations and ionic movement in the crystal lattice.
Ionic conduction rates exceeded 1 mS/cm under specific phonon-ion interaction conditions.
Experimental data confirmed theoretical predictions on the enhancement of ionic conduction through coupled interactions.

Implication

This research demonstrates enhanced ionic conduction through phonon-ion interactions in solid electrolytes, suggesting new material design pathways.

Abstract

Ionic conduction in solids that exceeds 1 mS/cm is predicted to involve coupled phonon-ion interactions in the crystal lattice. Here, we use theory and experiment to measure the possible contribution...
