The electrode's effective electronic conductivity (σe) serves as a chosen parameter to provide a quantitative assessment of the electrode's electronic percolation properties. This parameter is an observable devised to encompass electronic properties of the simulated dried and calendered electrodes. Herein, the description of the voxel-based flux simulations to determine effective σe. The flux simulations were performed using the ConductoDict module of GeoDict (Math2Market). The σe of the microstructures was determined by solving the Poisson equation within the simulation domain, while applying a 1 V potential difference between opposite sides along the z-direction (perpendicular to the calendering plane). Subsequently, Ohm's law was employed to derive the σe. Specifically, the intrinsic electronic conductivity values of AM and CBD phases were set to 0.005 S m -1 and 15.93 S m -1 , - respectively. PBCs were considered for the outer xz and yz planes.
