A Multinuclear NMR Study on the Speciation in the Liquid-Phase Synthesis of Sulfide-Based Electrolytes for All-Solid-State Lithium Batteries.

ABSTRACT: The preparation of Li₂S-P₄S₁₀ (LPS) solid electrolytes for all-solid-state lithium batteries through liquid-phase methods has attracted much attention over the last years. One of the most critical aspects to be clarified is how speciation affects the ionic conductivity of the synthesized materials, which is often lower than that obtained by other synthetic approaches. This paper shed some light on the species formed upon the reaction of Li₂S and P₄S₁₀ in acetonitrile under mild conditions, exploring a wide range of Li₂S/P₄S₁₀ molar ratios, by means of multinuclear/multidimensional NMR spectroscopy and single-crystal X-ray diffraction. Specifically, ³¹P NMR spectroscopy clearly evid
