The electrodes δ 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 is used to obtain the δ. 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. PB conditions were considered for the outer xz and yz planes. The τ geo values were calculated according to τ = √
