shown in Figure . The depicted values are calculated according to Eq. 4 using the experimental (markers) and effective medium modelled effective conductivities (dashed line and shaded area) as input parameter. Moreover, the thicknesses L and current densities i of the cathodes later investigated as a function of the CAM volume fraction are utilized for the calculation. These are in the range of 85 μm to 73 μm, and 0.24 mAh•cm -2 to 0.49 mAh•cm -2 (0.134 C) for ΦCAM between 0.32 and 0.74 at constant cathode mass, respectively. An overview of the parameters is given in Table of the Supporting Information.
