Analysis of Argyrodite Solid Electrolyte Degradation Using High-Frequency EIS
Abstract Argyrodite-type sulfide solid electrolytes (Li7−xPS6−xClx, LPSCl) deliver room-temperature ionic conductivity exceeding 1 mS/cm—among the highest of any inorganic solid electrolyte—but react rapidly with trace moisture, generating H₂S and…
