Lithium-sulfur batteries are a promising alternative to lithium-ion batteries due to their low weight and the high availability of sulfur. In addition to research on material aspects, scalable processes are needed to manufacture tailored sulfur cathodes with high-energy densities. Therefore, this work focuses on the usage of mechanical processes to prepare defined carbon-sulfur composite materials that are subsequently processed to electrodes. DEM simulations are used to calculate the necessary power input and the resulting stress energy for different mechanical processes.
