FestBatt2-Prod – BMBF Cluster of Competence for Solid-state Batteries Platform Production

Solid-state batteries are a promising concept for storing electrical energy. Compared to already established energy storage technologies, they are characterized by potentially higher storage capacity, shorter charging time and higher safety. This is due to the use of a solid electrolyte, which enables the use of new electrode materials. In order to industrialize solid-state batteries, production concepts must be worked out with regard to plant and process technology, occupational safety, costs and, in particular, quality assurance.

Project Details

The production platform of the BMBF Cluster of Competence for Solid-state Batteries
"FestBatt 2" ("FB2-Prod") works in an interdisciplinary way on the production, optimization, processing and upscaling of solid-state batteries and their components. The central objective of the project is the research and development of a scalable, quality-assured production of high-performance solid-state batteries based on the solid electrolytes investigated in the material platforms of the cluster.

Within the sub-project of the Institute for Machine Tools and Industrial Management (iwb) of the Technical University of Munich, a fundamental contribution to the establishment of the quality assurance in the industry-related production of solid-state batteries is to be developed. Among other things, a catalog will be created that derives the central quality characteristics from the product parameters and describes how they are influenced by the process parameters. All material systems used in the FestBatt2 cluster of competence will be considered.

Four university and five non-university research institutes are collaborating in the project: The production technology institutes of the TU Braunschweig (IWF), the Karlsruhe Institute of Technology (wbk) and the TU Munich (iwb) as well as the Institute for Particle Technology (iPAT, TU BS). Furthermore, the Fraunhofer Institutes for Manufacturing Technology and Advanced Materials (IFAM), for Ceramic Technologies and Systems (IKTS), for Surface Engineering and Thin Films (IST) as well as for Material and Beam Technology (IWS) and the Forschungszentrum Jülich.


The iwb would like to thank the Federal Ministry of Education and Research (BMBF) and the Project Management Organisation Jülich for funding this research project.
