June 4, 2025 – Electric mobility is progressing rapidly. To accelerate this development, Germany is aiming to significantly expand battery cell production. Manufacturing methods must also become more energy-efficient and cost-effective. For this purpose, a research team at the Fraunhofer Institute for Material and Beam Technology (IWS) in Dresden has developed DRYtraec, a groundbreaking method for producing battery electrodes in a more affordable and environmentally friendly way.
DRYtraec (Dry Transfer Electrode Coating) eliminates the need for toxic solvents used in conventional processes, and it also does away with the energy-intensive and expensive drying of electrode layers.
The researchers were awarded the Joseph von Fraunhofer Prize 2025 for this innovation during the annual Fraunhofer conference.
