Lithium–sulfur batteries are nearly ready to be commercialized. However, each material composition has specific challenges regarding its adaption to state of the art production lines of lithium‐ion batteries. The influence of the dispersing and calendering process on the battery performance is investigated with an easy‐to‐implement material approach and a solvent‐based process. The slurry is treated by different dispersing intensities using an extruder and a triple roller mill, which leads to increased energy densities. The coating is calendered to increase the energy density by maintaining the specific capacity. The reactions within the sulfur cathodes are investigated by evaluating the potentials of the upper and lower voltage plateaus. It was determined that the variation of the process parameters leads to a changed reactivity of the polysulfide reactions but not to a shift of the sulfur utilization within the sulfur cathodes. The process parameters influence the pore structure of the cathode, resulting in different sensitivities for higher C‐rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
