In-House Battery Lab
In-House Battery Lab

Our competence Center for R&D and Cell Prototyping

Situated in the heart of Berlin, our Chem4Batteries lab collaborates with talent from TU Berlin, Humboldt University, and the Fraunhofer Institute as part of the Berlin battery ecosystem. It is adjacent to Fraunhofer IZM, an institute specialising in microelectronics with clean room wafer production facilities. We utilise advanced analytic tools to evaluate battery materials, battery cells and make lab-based battery cell prototypes.
