behavior of the electrode. The pronounced difference in performance between calendering degrees at these rates can be attributed to variations in tortuosity factor and the accessibility of charge transport pathways. This is in line with the findings of Minnmann et al. , who demonstrated by modeling ASSBs electrodes corresponding to different SE particle sizes, that high C-rate performance is constrained by kinetic limitations, including increased resistance in charge transport pathways and decreased interfacial contact between AM and SE. As a result, calendering plays a significant role in eliminating these kinetic bottlenecks. On the other hand, at lower C-rates, the electrode performance is more influenced by thermodynamic factors. The relatively small difference in specific capacity across calendering degrees at low C-rates suggests that kinetic limitations are less critical under these conditions. Instead, microstructural heterogeneities in the electrode become the dominant factor affecting performance.
