The ability of lithium ions to diffuse through the pore network of the structure is a crucial factor for the good performance of electrodes. Since this is highly dependent on the arrangement of the different phases along the electrode, characterizing it allows comparing DL predictions vs. DEM results in meaningful terms. In order to do this, stationary state diffusion calculations allow to determine tortuosity factor and effective diffusivity values across the thickness of the electrode. Fick's laws are solved along the pore network, defining periodic boundary conditions on the outer planes in the x and y directions, and setting Li + concentration as 0 mM and 1 mM on the opposing outer planes in the z direction.
