The first and most important feature of the drying model developed here is its capability of mimicking the additives (here CBD) migration as a function of the DR. here, the DR was defined through the RSF applied to CBD2 (central region) and CBD3 (top region), i.e. the higher those values, the higher the DR. Figure illustrates the 3D electrode mesostructures obtained at different DRs, with at their bottom the RSFs of the center (RSF2) and top (RSF3) CBD particles, reported as RSF2 / RSF3. The RSF of the CBD in the bottom (CBD1) is for definition kept constant to 1, as discussed in the previous Section. From these structures, it can be already observed that the higher the DR (from left to right), the higher the degree of heterogeneity, i.e. more CBDs particles in the top region of the electrode respect to its bottom. To quantify it, the evolution of CBD fraction for each region (CBD1, CBD2 and CBD3) along the drying is reported in Figure for the 4 DRs considered. These results give us 3 main information: (i) the higher the DR, the higher the fraction of CBD3 at the expense of CBD2 and CBD1. (ii) the CBDs migration does not take place all along the drying, but rather in a specific time range. (iii) the time at which the CBDs migration starts and ends depends on the DR. Both (i) and (ii) have been found experimentally, as discussed along the Introduction, indicating that the model is capable of reproducing those trends.
