Our offer

The film coating line can be used to coat current-conducting films for lithium-ion battery cells.

This includes measurements of relevant process parameters using numerous sensors and imaging test methods. This enables, for example, the experimental process validation of the electrode production of new battery cell technologies (plant poster; PDF).
