  "abstract": "Moisture instability of sulfide solid electrolytes limits practical use in all-solid-state batteries. Spatially resolving gas--solid reactions during moisture exposure remains challenging. Here, cryogenic four-dimensional scanning transmission electron microscopy (cryo-4D-STEM) maps nanoscale degradation in low- and high-Cl argyrodite electrolytes, Li\\(_6\\)PS\\(_5\\)Cl and Li\\(_{5.5}\\)PS\\(_{4.5}\\)Cl\\(_{1.5}\\). Li\\(_6\\)PS\\(_5\\)Cl undergoes predominantly surface-localized degradation that progressively extends inward, whereas Li\\(_{5.5}\\)PS\\(_{4.5}\\)Cl\\(_{1.5}\\) exhibits rapid interior amorphization accompanied by outward chloride redistribution. Density functional theory calculations indicate a lower chloride-migration barrier along the modeled pathway in the higher-Cl composition, while chloride removal and vacancy formation distort the PS\\(_4^{3-}\\) framework and may destabilize the lattice. Surface treatment suppresses detectable large-scale chloride segregation and improves moisture tolerance, retaining 99.9% of the capacity measured at the start of 0.33 C cycling after 150 cycles. These results identify chloride redistribution as a key process in degradation propagation and suggest a route toward moisture-tolerant solid-state batteries.",
