Summary of the project:
In this project, two promising approaches in battery research are combined by examining the dry processing of sulfide-based solid-state batteries. Dry fabrication offers advantages in terms of energy and cost savings, as it eliminates complex drying processes and avoids the use of toxic solvents. Solid-state batteries are expected to deliver higher energy density compared to conventional lithium-ion batteries, particularly if the use of lithium metal or silicon as the anode and the bipolar stacking of individual cell stacks can be successfully implemented.
The project focuses in particular on the influence of electrolyte particle size on the cathode microstructure and thus on cell performance, as well as on the establishment of a suitable processing method with an emphasis on electrode and separator densification. The project is being carried out in close collaboration with Osaka Metropolitan University in Japan.
