EL-CELL organizes seminars and training in its laboratory to support researchers in effectively using our products and impart knowledge about battery testing. All necessary equipment, tools, and materials are available in our laboratory for a successful seminar, but participants can also bring their own devices or materials for testing.

All seminars are held by Dr. Matthias Hahn, a passionate electrochemist and co-founder of EL-CELL. Matthias has a PhD in physical chemistry and has gained extensive research experience as an electrochemist over 15 years working for Honeywell, Daimler, and the Paul-Scherrer-Institute. He offers consulting for customers on the effective use of EL-CELL devices. His practical and easy-to-understand explanations make it easier for seminar participants to enter the subject matter. He is also open to questions that might arise after the seminar.

We offer free hotel reservations and shuttle service between accommodation and the laboratory. To register, please use the form at the end of this page.

Description:

Our two-days seminar covers a broad range of topics beginning with the basics of Li-ion battery testing and ending with advanced electrochemical operando techniques using the latest test equipment from EL-CELL and other leading equipment manufactures in the field. In the hands-on sessions of the seminar, you will build your own battery test cells and run your own electrochemical tests. Both the practical and theoretical sessions will be guided by Matthias Hahn, a passionate electrochemist and co-founder of EL-CELL. Special emphasis is put on the various failure modes of experimentation, common pitfalls, possible artifacts and on how to identify and avoid them.
