Regarding the Si content impact on the slurry, the formulation with lower Si content is more viscous due to a more significant presence of graphite with an irregular particle shape, increasing the interparticle friction. The slurry rheology impact on the coating was studied through different comma gaps. The electrodes coated at 300 µm detached from the current collector, while the electrodes coated at lower comma gap showed appropriate adhesion properties. Then, symmetric cell measurements and cycling performance allowed us to evaluate the calendering effect on the coated electrodes for Si8% and Si15% formulations. The highest electrochemical performances are reached for the electrodes with the lowest ionic resistance. The Si8%/Gr83% electrode corresponds to a porosity of 45% (calendered 20% of the thickness). In comparison, the Si15%/Gr76% electrode showed acceptable but insufficient cycling performance for porosities between 46% and 57%, indicating that a higher level of engineering is needed to improve the performance. Finally, we believe that manufacturing process data and parameter correlations are useful for calibration and validation of physical and machine learning models, as we have evidence in the ARTISTIC project.
