a Coulombic efficiency (CE) of Li|Li6PS5Cl0.5Br0.5 | Li6-xAgxPS5Cl | SUS half-cells at 60 °C (x = 0, 0.2, 0.4, and 0.6). b Critical current density measurement of the Li|Li6PS5Cl0.5Br0.5 | Li5.4Ag0.6PS5Cl | SUS half-cell. The current density was varied for both charge and discharge, and the areal capacity was kept constant at 1.0 mAh cm−2. c–g Cross-sectional SEM-EDS images at (c) OCV, after (d,e) discharge at 0.005 V, (f) Li plating at 5.0 mAh cm−2, and (g) Li stripping to 0.1 V in the first cycle. The current density and operating temperature were fixed at 1.0 mA cm⁻² and 60 °C, respectively. h Cycling performance and (i) Voltage profiles of the pouch-type initially anode-free ASSB at 60 °C. The capacities in (h, i) refer to discharge capacities.
