Competence cluster solid-state electrolytes and batteries (FestBatt)

Funded by: BMBF

Contact : Dr. rer. nat. Peter Michalowski, Moritz Hofer

Summary of the project:

All-solid-state batteries (ASSBs) are currently considered as potential further development of lithium-ion batteries with liquid electrolytes. In two consecutive project phases (3 + 3 years), the research will range from the production and scaling up of suitable solid electrolytes (1. phase) to the development of necessary processes for efficient half cells and the construction of full cells (2. phase).
The starting point for FestBatt is the urgent need for high-quality solid electrolytes and technical concepts for the processing of solid electrolytes. The primary objective of the first phase of the project is to provide a sufficient material basis for the rapid and critical evaluation of ASSB concepts by industrial companies and application-related institutes.
Solid electrolytes can be divided into three groups: a) thiophosphates/sulphides, b) oxides/phosphates and c) polymers. Since the processing of the different classes of solid electrolytes is fundamentally different, the specific processing aspects in the three material clusters must be defined.

Goals and tasks of iPAT:
The sub-project of the iPAT “process-product interaction in the production and processing of sulphidic solid electrolytes” (Pro3S) has the following main goals:

  • Evaluation and process analysis of scalable, dry and wet mechanochemical syntheses of lithium thiophosphates/sulphides
  • Characterization of the resulting material and surface properties for evaluation of the process routes and for generation of relevant material properties, as well as to get data for the evaluation of the material compatibility with the most important electrode materials
  • Evaluation of sulphidic solid electrolytes with regard to their processability to electrodes/separators and the resulting performance
    Partners in the sub-project:

    Physikalisch-Chemisches Institut (PCI) & Laboratorium für Materialforschung (LaMa) der Justus-Liebig-Universität Gießen (JLU), Max-Planck-Institut (MPI) für Festkörperforschung Stuttgart, Fraunhofer-Institut für Schicht- und Oberflächentechnik (IST) Braunschweig
