Electrode calendering is critical for improving their conductivity and mechanical strength, which are crucial for maximizing the volumetric energy and power densities of battery cells. For SSBs, the goal is to create highly compact electrodes with minimal porosity, enhancing ionic conductivity, rate capabilities, and the utilization of active material . Therefore, understanding the impact of calendering on the electrode microstructure is essential for identifying optimal compression parameters that address these challenges. Our calendering model simulates the actual calendering process by using a plane moving downward at a constant speed to compress the electrode. The interactions between the wall and the particles are modeled using GH FFs, with force parameters detailed in Table in the SI. We assume that the CBD phase is 50 % composed of nanopores . During calendering, the PBCs are applied in the lateral x and y directions, while the surface perpendicular to the z-axis remains fixed. As the plane descends, the particles rearrange due to the force imposed on them.
