TL;DR: The atomic and electronic structures of binary Li2S-P2S5 glasses used as solid electrolytes are modeled by a combination of density functional theory (DFT) and reverse Monte Carlo (RMC) simulation and it is found that the edge sharing between PSx and LiSy polyhedra increases at a highLi2S content, and the free volume around PSx polyhedRA decreases.
Journal ArticleDOI
Synthesis, structure and lithium ionic conductivity of solid solutions of Li 10 (Ge 1-x M x )P 2 S 12 (M = Si, Sn)
TL;DR: In this article, Li 10 (Ge 1− x M x )P 2 S 12 (M = Si, Sn) was synthesized and the ionic conductivities of the resulting solid solutions were determined.
Journal ArticleDOI
