Objectives and Ideas

In the Laboratory of Physical Chemistry, chemical reactions that take place in energy storage systems can be studied and students can experience them e.g. in the practical course Physical Chemistry. In addition to 12 workstations, there is a fume cupboard, a preparation area and an analytical workstation with an ion chromatograph for the analysis of extinguishing water samples from battery tests.
In the Energy Storage Practical Course, students can gain a basic understanding of electrochemical storage and experience the basic behaviour of a cell in practice. Students learn how to handle the most important characteristics and parameters of battery cells and determine these independently using test setups - skills that will later be required to design energy storage systems or integrate them into a system.
