  • Superionic materials are of interest for solid-state batteries or thermoelectrics, yet a clear understanding of the atomistic mechanisms is lacking. Here it is shown that transverse acoustic phonons persist above the superionic transition in argyrodite Ag8SnSe6, and that the free-Se sublattice controls fast Ag cation diffusion.

  • Understanding the mechanism of ionic diffusion in superionic materials is crucial for their potential applications in solid-state batteries. Now liquid-like dynamics that break the Debye law of lattice dynamics have been demonstrated in a lithium electrolyte.
