driven by the orders of magnitude loss in effective ionic conductivity (Figure ). This strong increase manifests as a 90% decrease of the cathode utilization. With that, the δ-parameter captures the observed trends in the initially achieved capacities qualitatively. Moreover, a decrease of QCAM with the logarithm of δ can be observed, acknowledging the scattering in the dataset (Figure ). Not considered in this analysis is the residual porosity of the electrodes. Nonetheless, given that the relative density does not change significantly with an average of 85±3% for all investigated electrodes, the effect is assumed to be negligible in first approximation.
