The increased understanding of the effects of manufacturing on the microstructure, allowed by the simulation, enables us to study and explain the electronic and ionic conductivity of the system. Both the electronic and ionic conductivities are shown as a function of the calendering degree in Figure . We observe a steady increase of both the electronic and ionic conductivity as the calendering degree is increased. This trend matches observations made in experiments and is a desired effect of increasing the calendering degree, as this allows for better percolative pathways for both ions and electrons. The observed trends are explained with the shorter and less tortuous pathways electrons ions need to take on account of the smaller distance between top and bottom of the microstructure, thus increasing their electronic and ionic conductivity, although we would expect even higher values for larger interfacial areas between materials.
