Electrochemical Energy Storage

At the Chair, we are dedicated to the holistic research and development of modern battery systems – from the cell to the complete battery system. Our goal is to enable powerful, safe and long-lasting energy storage solutions for a wide range of applications: from portable devices and electric vehicles to stationary storage systems for the energy turnaround.

Our research focuses on the behavior and aging of electrochemical energy storage systems depending on the specific application scenario. We not only analyze the electrochemical performance, but investigate in particular the causes and mechanisms of degradation under realistic conditions.

A central element of our work is the creation of models to describe the electrochemical, thermal and mechanical behavior of batteries. These models serve both the fundamental understanding and the prediction of states and ageing processes under various load profiles. In addition to physically based models, data-driven approaches are increasingly being used – in particular AI-supported methods that can efficiently evaluate large amounts of data and recognize complex relationships.

Building on this, we develop and refine diagnostic procedures with which battery states such as State of Charge (SoC), State of Health (SoH) or safety risks can be determined precisely and reliably. These findings flow directly into the design and optimization of Battery Management Systems (BMS), which are essential for safe, efficient and sustainable operation.

In addition to investigating individual cells, we look at and develop battery systems at module and pack level and deal with issues of system integration, thermal design and safety technology.

In contrast to basic materials science research, our work concentrates on systemic and application-oriented aspects of battery development. In this way, we make an essential contribution to the further development of modern energy storage technologies in an increasingly electrified everyday life. Our research activities are carried out as part of publicly funded projects with and without industrial participation as well as on behalf of industry.
