Structural analysis and ionic conduction mechanism of sulfide-based solid electrolytes doped with Br.

ABSTRACT: Sulfide glasses can exhibit notable ionic conductivity because of annealing-associated crystallization. One well-known example is Li₇P₃S₁₁. Our research showed that adding bromine (Br) to Li₃PS₄ sulfide glass results in a similar crystal structure and high ionic conductivity comparable to that of another compound Li₁₀GeP₂S₁₂. This structure differs from the PS₄ anion framework of Li₃PS₄. In addition, the ionic conductivity decreases owing to a structural transition to the β-phase. Herein, we present our findings on the local structure of Li₃PS₄ sulfide glass and its crystallized glass ceramic with the addition of Br. This analysis relies on the pair
