Lewis Acid Probe for Basicity of Sulfide Electrolytes Investigated by ¹¹B Solid-State NMR.

ABSTRACT: Sulfide-based solid-state lithium-ion batteries (SSLIB) have attracted a lot of interest globally in the past few years for their high safety and high energy density over the traditional lithium-ion batteries. However, sulfide electrolytes (SEs) are moisture-sensitive which pose significant challenges in the material preparation and cell manufacturing. To the best of our knowledge, there is no tool available to probe the types and the strength of the basic sites in sulfide electrolytes, which is crucial for understanding the moisture stability of sulfide electrolytes. Herein, we propose a new spectral probe with the Lewis base indicator BBr₃ to probe the strength of Lewis basic sites on various sulfide electrolytes by ¹¹B solid-state NMR spectroscopy (¹¹B-N
