Fig. 1: Schematic representation of void and dendrite formation during critical current density (CCD) measurements.
From: Standardizing critical current density measurements in lithium garnets
a Schematics of the impact of the amount of stripped Li from the Li/LLZO interface, shown as areal capacity, on the change of Li/LLZO contact area and actual current density. b The measured values of the CCD (black squares) as a function of areal capacity limitation (ACL) per half-cycle. The regions I, II, and III represent the ranges of ACL steps at which CCD values can be considered overestimated, nearly correct and underestimated, respectively. The dashed blue line shows the highest achievable value of CCD (estimated CCD).
