Toward Understanding of the Li-Ion Migration Pathways in the Lithium Aluminum Sulfides Li₃AlS₃ and Li_4.3AlS_3.3Cl_0.7 via ^6,7Li Solid-State Nuclear Magnetic Resonance Spectroscopy.

ABSTRACT: Li-containing materials providing fast ion transport pathways are fundamental in Li solid electrolytes and the future of all-solid-state batteries. Understanding these pathways, which usually benefit from structural disorder and cation/anion substitution, is paramount for further developments in next-generation Li solid electrolytes. Here, we exploit a range of variable temperature ⁶Li and ⁷Li nuclear magnetic resonance approaches to determine Li-ion mobility pathways, quantify Li-ion jump rates, and subsequently identify the limiting factors for Li-ion diffusion in Li₃AlS₃ and chlorine-doped analogue Li_4.3AlS_3.3Cl_0.7. Static ⁷Li NMR line narrowing spectra of Li₃AlS₃ show the exist
