We describe in this section the charge transport simulations carried out to correlate microstructure with transport kinetics. The calculations to determine the effective conductivities (δ) and geometric tortuosity (τg) were performed employing the ConductoDict and DiffuDict modules of GeoDict 2023 (Math2Market) , using a standard desktop computer. δ and τg are two chosen parameters to provide a quantitative indication of the effect of calendering degree on the electrode's electrochemical performance. They are simple observables defined to account for both ionic and electronic properties of the simulated uncalendered and calendered electrodes. The electronic effective conductivity δe was calculated by solving the Poisson equation in the simulation domain, applying a 1 V potential difference between opposite sides along the z direction (perpendicular to the calendering plane). Then, Ohm's law was used to obtain the δe. The electronic conductivities of the AM and the CBD phases were set to 0.005 S m -1 and 15.93 S m -1 , respectively. The τg values were calculated from the determined effective diffusivity according to:
