Successively, the influence on cathode utilization is investigated and related to the transport characteristics of the system. The porous electrode theory developed by Newman and Tobias is revisited and a dimensionless descriptor identified to describe transport limitations of the system. This descriptor is used to qualitatively guide the understanding of our results. From this, it is shown that high volume fraction CAM cathodes can be realized that show good cathode utilization at low applied current densities even when aiming for thicker electrodes. Nonetheless, lower rate capability at higher applied current densities is a consequence of increasing the cathode loading, i.e., the cathode energy density. With that, this work shows the general capabilities of Li2FeS2 as CAM in solid-state batteries and reveals limitations in the field of solid-state batteries in general that have to be targeted by future research.
