What do you like about science?

The opportunity to discover new things and develop solutions to previously unsolvable problems. I like the diversity and the challenge of keeping up with constant progress.

If you have not become a scientist, what would you be today?

I would not have dark circles under my eyes, sleep regularly and have a balanced social life. I’m just kidding. In fact, I like my job very much and am convinced of what I do. If I had made a different career choice, I would have become a carpenter.

What is your favorite place at work? Outside work?

At the institute, I prefer to focus on developing new equipment and making additions to existing battery process technology plants in the workshop. In my free time I enjoy nature, especially the area around my hometown.

What is your role in the SUBLIME project?

I am scaling up the dispersion process of suspensions for the production of separator and cathode layers. Subsequently, I am responsible for their production on an industrial scale using a twin screw extruder and the following pouch cell assembly. Furthermore, I developed cell press devices which are used by the SUBLIME partners to cycle solid-state battery cells under defined pressure.

How do you think will the results of SUBLIME contribute to a more sustainable world? How will the world be different after SUBLIME?

Honestly, I don’t think that a single project will change the world. However, I am optimistic that many projects like SUBLIME will lead to a gradual development of battery technology and ultimately to a more sustainable, independent and green Europe.

What research are you conducting at your institution and how is it applied in the SUBLIME project?

At the Institute for Particle Technology, research is conducted in different areas of mechanical process engineering, including battery technology. We provide the entire process chain from material synthesis to recycling, focusing in particular on production scales at industrial level. In SUBLIME, we contribute capabilities for the large-scale production of solid-state batteries.
