CampusZelle

The goal of the “CampusZelle” project is to develop an innovative solid-state battery with unique performance characteristics for both stationary and mobile applications. Compared with conventional solutions, significant advantages in safety, volumetric energy density, fast-charging capability, and sustainability are expected.

Since solid-state batteries are not built with liquid electrolytes, the risk of fire is significantly reduced. With silicon and sulfur compounds, the material concept relies on readily available raw materials, enabling sustainable and resilient production in Europe. Existing expertise among Saxon companies in the semiconductor sector, as well as their experience with processing in dry atmospheres, provides excellent conditions for technology development in Saxony.

At the same time, the project aims to strengthen collaboration among the research institutes of the Fraunhofer Battery Campus Dresden–Freiberg (Fraunhofer IWS, IKTS, FEP, IISB) along the value chain of the new generation of battery cells and to leverage synergies. As a result of “CampusZelle”, battery-cell demonstrators and the necessary technology and knowledge platform will be available. A Technology Readiness Level (TRL) of at least 4 will be achieved, and for individual process steps and cell components, a TRL of 5 is expected.

Through the project objectives, innovation potential is created for battery manufacturers and users, as well as for machinery and plant engineering companies, laying the foundation for successful innovation transfer to industry.

It is important to emphasize that both the overall result (the battery cell) and individual process steps, process solutions, and battery components can be further developed and transferred.
