Challenge

Solid-state batteries offer a promising opportunity to improve the safety and performance of current battery technologies. Since the materials required for solid-state batteries are scarce, the basic principles for material production and processing are being investigated in FestBatt. In the PriMeLIB project, Fraunhofer IST is working on scaling up these process technologies.

Solution

Interdisciplinary cooperation of basic and applied research institutes that are in close coordination with industry is crucial for identifying relevant issues in the field of new solid-state battery technologies. Fraunhofer IST is contributing to this project by providing the necessary experience in process engineering and process technology, particularly for the development of scalable manufacturing processes for promising sulfidic solid electrolytes (so-called thiophosphates).

Added value

A key result of the work at Fraunhofer IST is the development of optimized and scalable synthesis processes for solid sulfide electrolytes. Both the solid sulfide electrolytes produced and the process concepts developed can be transferred to the planned second phase of FestBatt and further advance research of new cell concepts.
