To determine this effective diffusivity value (Deff) through the dried electrode thickness, stationary state diffusion calculations are performed by solving the Fick's laws throughout the pore network by using the DiffuDict module of GeoDict 2024. Taking into account that we considered the diffusion coefficient in the pores bulk equal to 1, the Bruggeman relationship gives us the diffusion coefficient in the micropores of the CBD as ξ , where ξ is the microporosity and is assumed to be equal to 0.5 for both simulated and predicted dried electrode microstructures. The boundary conditions are defined as periodical in the tangential directions
