From a purely data point of view, an average contact surface area error % of around or below 10 % indicates that our model is predicting in an accurate way the geometrical arrangement between the phases. However, since the contact surface area is only one of the properties affecting the electrode electrochemical performance (e.g. controlling for instance the intercalation/de-intercalation kinetics of lithium ions, and the electronic charge transfer between AM and CBD), we need to go beyond by also using other electrode functional metrics. Even though an explicit structure-property linkage was not included in the DL model, the calculation of additional electrode functional properties such as porosity, diffusivity and tortuosity factor, are crucial for characterizing and comprehending the structural conformation of a microstructure. In this approach, the listed properties are also used as metrics to compare the similarity of the DL predicted microstructures vs. the DEM targeted ones. Numerical calculations of the three properties, porosity, diffusivity and tortuosity factor, are determined according to the method described in the methodology section and results shown in Figure .
