Observation of Liquid Phase Synthesis of Sulfide Solid Electrolytes Using Time‐Resolved Pair Distribution Function Analysis

Time‐resolved pair distribution function (PDF) analysis is performed to clarify the formation mechanism of Li3PS4 sulfide solid electrolytes in liquid phase synthesis with acetonitrile (AN), tetrahydrofuran (THF), and ethyl acetate (EA) solvents. This aims to clarify the relationship between their f...

Description
Summary:Time‐resolved pair distribution function (PDF) analysis is performed to clarify the formation mechanism of Li3PS4 sulfide solid electrolytes in liquid phase synthesis with acetonitrile (AN), tetrahydrofuran (THF), and ethyl acetate (EA) solvents. This aims to clarify the relationship between their formations and lithium ionic conductivity. A complex is formed between the precursor of the sulfide solid electrolyte and each solvent during the liquid phase synthesis. The ratio of the solvent to the electrolyte is 3.03 in THF solution. The formation speed of precursors of sulfide solid electrolytes increases in the order AN
