The effect of solvent on reactivity of the Li₂S-P₂S₅ system in liquid-phase synthesis of Li₇P₃S₁₁ solid electrolyte.

ABSTRACT: Synthesis technology for sulfide-based solid electrolytes based on liquid-phase processing has attracted significant interest in relation to achieving the optimal design for all-solid-state batteries. Herein, guidelines to solvent selection for the liquid-phase synthesis of superionic conductor Li₇P₃S₁₁ are described through systematic examination. 70Li₂S-30P₂S₅ system, a source of Li₇P₃S₁₁, is treated via a wet chemical reaction using eight organic solvents with different physical and chemical properties (i.e., dielectric constant, molecule structure, and boiling point). We reveal that the solvent's polarity, characterized by the dielectric constant, plays an important role in the formation
