Characterization of calandered cathodes of li-ion battery cells using confocal and electron microscopy
The capacities and volumetric energy densities of li-ion battery cells can be raised by applying higher compressions on the electrodes. The calendering process does not only have a notable effect on the coating, it also has an effect on the current collector foil. In this study the focus is on the cathode and in particular […]
Methods for scalable production of solid-state batteries based on sulfide solid electrolytes
The increasing demand of electrically powered vehicles requires new battery technologies with higher safety and better performance than common lithium ion batteries (LIB) can provide. Solid-state batteries (SSBs) with a solid electrolyte (SE) of high ionic conductivity instead of organic liquid electrolytes are the most promising candidates to reach both requirements at the same time. […]

Compaction of Separator and Composite Cathode Sheets for Sulfide-based All-solid-state Batteries
Increasing the sustainability of energy storage systems is one of the main challenges of the 21st century. The efforts to address this issue have led to a high level of attention for electrochemical storage solutions. As a result, conventional lithium-ion batteries developed rapidly in recent years and their maximum energy density will be reached soon. […]
The FestBatt-Cluster of Competence for Solid-State Batteries
You may already have heard a lot about solid-state lithium-ion batteries (SSB). They are considered an alternative to liquid-electrolyte-based lithium-ion batteries due to many claimed advantages. These claims motivate researchers from academia and industry from all around the globe, which makes SSBs a highly dynamic field. But which kind of safety is referred to when […]
