Frank as a battery cell expert is a great support for training on cell topics, which we needed for our battery development projects. I appreciate his flexible, modern teaching approach and the interactive working atmosphere.

Frank is very knowledgeable. He was answering all upcoming questions very detailed, using good examples.

It was an excellent time to learn from a Li-Ion battery expert. Frank's coaching style was fantastic. My impression during and after class was of eagerness to answer questions and provide all necessary information.

This course has taught me a lot about how batteries are built, tested, and what can go wrong. It has helped me understand battery systems, which are more and more often used in the maritime industry. Thanks to Greenectra for giving me with the knowledge I need for my work.

I learned a lot during the compact session. All fundamental things related to Lion battery cells, testing, and safety were covered. Additionally, explanations from Dr. Richter to all participants during Q&A sessions were something that I highly appreciated a lot. Thanks again for the kind support throughout the course.

I enrolled in the course and found it extraordinarily well-structured and informative. The clear explanations and helpful quizzes and assignments have made the material easy to grasp. As a lecturer teaching the electrochemical energy storage and conversion system, I find this course highly beneficial.
