A benefit of studying computational models is the immediate availability of data in comparison to experiments. Through such computational models, properties of interest can be analyzed as soon as the in silico generated microstructure is complete. We therefore start with the analysis of the material distribution throughout the electrode and the change thereof upon calendering. Volume fractions for each material phase are plotted as a function of distance from the CC in Figure . A volume fraction is defined as the percentage of a given material within a distance [z, z + ∆z] from the CC, relative to the volume within this volume element. All color codes in Figure represent the different calendering degrees of the simulations ranging from low calendering degrees in blue to high calendering degrees in red. Plots in Figure represent the volume fraction of active material (Figure , top left), CBD (Figure , top right), pores (Figure , bottom left) and solid electrolyte (Figure , bottom right) at a given distance from the CC. For all microstructures, which are comparable to the microstructures of electrodes obtained from experiments and dried at low drying rates, similar trends are depicted for all calendering degrees, therefore we shall describe the effect of the distance from the calendering degree on the volume fraction first and subsequently elucidate the impact of the calendering degree on the volume distribution. At small distances from the CC, the active material has little to no contribution to the total volume fraction, the value appears to be zero and only increase at several micrometers from the CC. We observe, on the other hand, a relatively large contribution of CBD and solid electrolyte to the total volume fraction, which decreases at a distance of several micrometers to the CC. We explain this behavior on account of the realistic particles shapes and relative size of the active material. Since the active material is much larger than the solid electrolyte and CBD particles, only an edge of the particle will be in contact with the CC. The center of the active material particle will be several micrometers away from the CC. Therefore, we expect only a small amount of active material close to the CC, but a gradual increase as we move away. Likewise, the space that is not filled with the active material is filled with other materials on account of the smaller size and therefore better packing. Thus explaining the larger SE and CBD volume fractions close to the CC. Similar trends are observed for all materials at intermediate distances from the CCs. All volume fractions of the materials seem to fluctuate around a constant value for intermediate distances from the CC. Such a trend is expected, because of the homogeneous distribution of the materials as well as the homogeneous drying phase of the slurry. At distances opposite to the CC, all material volume fractions decrease towards zero. Such a gradual decrease is explained on account of the relaxed state of the electrode after the calendering roll is removed. Pores, on the other hand, appear to have a relatively constant volume fraction distribution over all distances from the CC, only at distances opposing the CC, do their volume fraction increase on account of the heterogeneous surface formed at such distances after the calendering roll is retracted. During calendering all materials in essence get pushed down. Slight fluctuations are present in the volume fraction distribution on account of the slight variability in material distribution. For distances close to the opposite side of the CC, volume fractions decrease to zero or close thereto on account of the fact that the electrode relaxes after the calendering roll is removed. Such a decrease in volume fraction occurs over the span of several micrometers, the calendering degree appears to have little to no impact on this. We continue with the analysis of the porosity of the system as the calendering degree increases. Porosities after the microstructure have relaxed as a function of calendering degree are depicted in Figure . Here, one observes that as the calendering degree increases, the porosity of the electrode decreases steadily from approximately P sim = 0.57 ± 0.01 in the uncompressed state to approximately P sim = 0.30 ± 0.02 at a 45% calendering degree. The decrease occurs non-linearly and even appears to speed up for higher calendering degrees, because the microstructure after the relaxation or springback has occurred. It is evident that as the calendering roll presses down on the dried electrode, the system under study will begin to decrease in volume on account of the added stress. This phenomenon is also reflected in the studied system, since as the pressure increases through the higher calendering degree, the pores present within the electrode begin to shrink. As the stress is increased, first the pores begin to close, on account of the high Young's modulus of the material phases present in the configuration. Such a mi- crostructural evolution is expected and desired. During calendering such a behavior is explicitly targeted, as it decreases the volume of inactive phases, such as pores, present in the electrode to increase the energy density of the electrode. Simultaneously the interfacial contact between all material constituents should increase, in order to allow for the formation of electronically and ionically percolation pathways, which also increases the performance of the electrode during cycling.
