Laboratory for Electrochemical Energy Systems

Brief description

The laboratory focuses on various areas of electrochemical energy conversion and storage on a laboratory scale (in particular, hydrogen technologies, CO2 recycling, and battery electrodes), as well as processes involving electrocatalysis and photocatalysis, degradation, homogeneity, and lifetime analysis, as well as related material and cell development or modification.
Target audiences for these activities include:
• Laboratory courses at the bachelor’s and master’s levels in the field of energy technologies.
• PR events and presentations, e.g., for companies, high school students, and the interested public.
• Student projects, practical projects, bachelor’s theses, and master’s theses in the areas of the topics mentioned above.
• Research conducted as part of commissioned work and collaborations with industry.
• Research conducted as part of externally funded projects.

Location: The Laboratory for Electrochemical Energy Systems is located in Room 6-209 on the Friedrich Streib Campus.
