Expertise for an electromobile future

Dresden "ExcellBattMat Center" contributes key components for new battery generation

more info

The Dresden "ExcellBattMat Center" (short: EBZ Dresden) is part of the cluster of competence for battery materials funded by the Federal Ministry of Education and Research (BMBF).

The EBZ Dresden bundles the expertise of the participating research institutes in materials research for new battery systems. In an interdisciplinary approach, the Dresden center develops new electrode materials, analyzes them with state-of-the-art characterization methods and transfers them into application-oriented prototype battery cells using innovative process technologies.

Topic 1

Electrode materials

Electrodes are key components of the battery cell and the electrode structure is decisive for the cell properties.

Accordingly, this topic focuses on the development of new electrode materials and their analysis of their mechanical and electrochemical properties.

Topic 2

Cell development

Negative and positive electrodes, as well as electrolytes and separators, are integrated in the battery cell. Coordination of all components with regard to electrochemical, but also structural-mechanical properties is crucial for high quality and improved battery functions. This topic thus focuses on the holistic battery cell developments.

Topic 3

In-situ characterization

In order to gain a fundamental understanding of the complex, electrochemical processes involved in battery cell operation, new methods for in-situ characterization are required. Studies of the material composition by means of spectroscopic methods and structural characterization by means of diffraction are used to analyze the new cell systems during operation.
