What do you like about science?

Science is instrumental for a better understanding of the world and turns knowledge in new technologies into a better life.

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

I am an engineer; I could have become a scientist in another life.

What is your favorite place at work? Outside work?

Hybrid mode, mixing R&D center and home office.

What is your role in the SUBLIME project?

I am the WP leader for battery cell design, pre-industrial scale-up, and manufacturing. I am mainly coordinating tasks and actions with partners.

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

Sulfide-based chemistry is one of the most promising technologies for high energy density solid-state batteries. It is one of the key items in the overall battery design roadmap for the transition towards electric vehicles, which is necessary for reducing tailpipe emissions.

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

Saft participates in the development of the formulation of the positive electrode and the solid electrolyte layer based on its almost 30 years’ experience in Lithium-ion technology. As a very experienced Li-ion cell manufacturer, Saft helps the project’s partners to define the most critical parameters for obtaining the best electrochemical performance.
