Our proposed model is used for the same formulation than in our extrusion experiments, excluding the PCL polymer, which is not considered here (Table ). We investigate the influence of the feeding approach, cohesion level and extruder speed on the materials mixing and resulting electrode microstructure. A cylindrical section is added at the extruder outlet (Fig. ) to mimic the cylindrical filament formed after the solidification of the paste on a conveyor belt downstream from the extruder. In the simulations, the electrode properties are analyzed in the microstructure obtained at the cylindrical section. Except case E, all simulations are carried out at 500 rpm in order to save computational time.
