🔋 Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li 6 PS 5 Br
📝 بینظمی آنیونی در Li6PS5Br رسانش یونی را افزایش میدهد اما رسانش حرارتی حدود ۰.۴ W/mK را تغییر نمیدهد.

💡 Novelty & Significance:
This study uniquely links anion site disorder to ion dynamics versus thermal transport in Li₆PS₅Br, showing disorder enhances Li⁺ diffusion but leaves thermal conductivity unchanged at ~0.4 W·m⁻¹·K⁻¹. The finding that diffuson-like modes govern heat transport, validated by bridging molecular dynamics with mesoscale porosity modeling, advances understanding of thermal management in solid-state batteries.
