Thermal properties of cubic NaSbS2: diffusion dominant thermal transport above the Debye temperature

We elucidate the thermal properties of superionic conductors, which are of intense current interest for solid-state battery applications. The temperature-dependent thermal properties of superionic NaSbS2 were investigated by analyses of appropriate models revealing that a predominant contribution to thermal transport above the Debye temperature is from thermal diffusion.

Automated summary

We investigate the thermal properties of superionic conductors for solid-state battery applications and find that thermal diffusion is the predominant factor contributing to thermal transport above the Debye temperature in superionic NaSbS2.
