Goals and idea

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.

Laboratory equipment and activities

Twelve workstations for internships:

  • Complete equipment for 6 experiments each for the practical course in physical chemistry
  • Complete equipment for 6 experiments each for the practical course Energy storage
  • Each workstation contains all experiments for the internships, all students carry out the same experiments at the same time
  • Two students per workplace

A deduction for:

  • Working with potentially dangerous substances
  • Openings of battery cells

An analytical workstation:

  • Metrohm 930 IC Flex ion chromatograph for determining the content of anions and cations in aqueous samples

Area for laboratory internships

The laboratory has 12 workstations for two students each. At each workstation all the experiments listed below can be carried out. The internships are carried out within the framework of the Electrical Engineering and Electromobility course of studies.

Winter semester: Practical course physical chemistry with the experiments

  • Reaction types and redox reactions
  • Potentiometry / acid-base titration
  • Galvanic elements and voltage series
  • Conductivity of electrolyte solutions
  • Faraday's law and fuel cell
  • DTA: State diagram of solder

Summer semester: Practical course energy storage with the experiments

  • Parameter determination of lithium-ion cells
  • Battery modelling and simulation
  • Battery status detection
  • Battery system technology: insulation and contact resistance
  • impedance spectroscopy
