Hands-on seminars

Join our two-day Hands-on Seminars on Li-ion battery testing in Hamburg, Germany

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

All seminars are held by Dr. Matthias Hahn, the Head of Consulting and Development 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 which might arise after the seminar.

We offer free hotel reservation and shuttle service between acommodation and the laboratory. In order to registrate, please use the form at the end of this page.

Individual on-site training is offered in addition to the hands-on seminars. Just ask.

Hands-on seminar :


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, head of development at 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.

Covered topics:

Consultation on the effective use of EL-CELL devices

Li-ion battery introduction: Working principles, terminology, materials used, related technologies (Li-metal batteries, Li-ion capacitators, super capacitators, dual intercalation batteries)

Safety and corrosion issues in the Li-ion research laboratory

Electrode making from powder to sheet

Pros and cons of different test cells (18650 test cell, Coin cells, Pouch cells, Swagelok® cells, Hohsen Corp., PAT-Cell)

Building 2- and 3-electrode PAT-Cells

Testing with PAT-Cells:

Lifetime and CC-CV cycle Tests

Impedance measurements

Cyclic voltammetry

Electrochemical in-situ/ operando techniques:

Experimenting with the PAT-Cell-Opto-10: Visualizing the gradients of electrode potential and lithium concentration

Experimenting with the PAT-Cell-Press: Quantifying the gassing during battery formation

Experimenting with the ECD-3-nano dilatometer: Measuring electrode dilation during charge and discharge

Hands-on seminar dates:

25-26 November 2021
