Forced Disorder in the Solid Solution Li₃P-Li₂S: A New Class of Fully Reduced Solid Electrolytes for Lithium Metal Anodes.

ABSTRACT: All-solid-state batteries based on non-combustible solid electrolytes are promising candidates for safe energy storage systems. In addition, they offer the opportunity to utilize metallic lithium as an anode. However, it has proven to be a challenge to design an electrolyte that combines high ionic conductivity and processability with thermodynamic stability toward lithium. Herein, we report a new highly conducting solid solution that offers a route to overcome these challenges. The Li-P-S ternary was first explored via a combination of high-throughput crystal structure predictions and solid-state synthesis (via ball milling) of the most promising compositions, specifically, phases within the Li₃P-Li₂S tie line. We systematically characterized the structural propertie
