Our lab experiments are carried out at a screw rotation frequency of 50 rpm. Tests at higher frequencies are planned to investigate its effect on the produced filament. While this extruder allows up to 400 rpm, due to the high viscosity of the paste, maximum feasible experiments should be at around 150 rpm. For industrial applications, extruders should allow higher frequencies. Numerical simulations can contribute to anticipate the effects at very high rotations in a cheaper and safer way. For comparison purposes, here simulations at 50 rpm (case E) and 500 rpm (case C) are carried out. Fig. shows the obtained 3D electrode microstructures for both cases. The lower speed case resulted in lower porosity, leading to slightly lower ionic conductivity, and higher electrical conductivity. Therefore, there is a compromise when increasing the rotation speed. In experiments, Dreger et al. found a compromise during the extrusion step in the wet electrode manufacturing. Increasing rotation speed under a given speed caused an increase of the electrical conductivity. However further increases of speed had the opposite effect. They pointed to the high reduction of the carbon agglomerates size as a cause for the decrease of electrical conductivity at very high speeds. Although, we do not explicitly consider the carbon in the simulation, we can study the agglomeration through our BC particles. To this end, we investigated and removed the AM particles in the obtained microstructures as a post-processing step. Then the coordination number is calculated to provide an idea of the BC-BC agglomeration. Fig. shows lower coordination numbers for the higher speed case. Thus, similar to the experimental observations, simulations confirmed that very high speeds decrease the size of the carbon agglomerates, which results in lower electrical conductivities. On the other hand, the lower speed case shows poor mixing, which can result in some decreasing of its electrical conductivity when modeling explicitly the carbon additive in future work.
