Center for Electrical Energy Storage

Electrical storage systems are a key component of the energy system. The “Center for Electrical Energy Storage” at Fraunhofer ISE with its advanced equipment and industry-oriented pilot systems offers a unique infrastructure for a broad-range of R&D Services along the entire battery value chain. With this, we want to increase the competitiveness of Germany as a production location and accelerate the progress of the energy transition.

Together with our industrial partners, we are driving forward the development of sustainable, safe and high-performance energy storage systems. Making use of the wide range of specialized equipment available in our labs, the Fraunhofer researchers apply their extensive expertise in simulation, technology assessment and data management. We provide the following services in four comprehensive laboratories:

Lab Battery Materials and Cell Production

For industrial customers, we develop processes first on a laboratory scale, then assist in bringing them up to the pilot scale and further optimizing them. Our focus is on sustainable processes such as dry coatings or rather the development and use of mini environments with the aim of reducing the production costs of battery cells.

Lab Characterization and Post-Mortem Analysis

We carry out detailed material and post-mortem analyses, identifying, for example, the causes of performance problems or failures. This allows us to significantly increase the safety of battery cells. Our available equipment enables us to perform our tests under inert conditions starting with opening of the cell through to the final analysis.

Lab Battery Engineering, Production and Testing

In this lab we deal with optimizing cell formation processes, customized electrical and thermal characterization, modeling of battery aging, temperature control, prototype construction, second life storage, innovative fast-charging techniques, destructive and non-destructive safety tests and the development of innovative test environments.

Lab Energy Storage Application and Innovation

With the available equipment in our laboratories, we can simulate energy systems with storage components and control them using energy management systems. Thus, we offer our partners an optimal environment for the development and qualification of operating and control strategies for storage systems.
