Revolutionary battery technology from Dresden: TUD scientist excellent!

The Joseph-von Fraunhofer Prize 2025 was on June 4, 2025 to Prof. Stefan Kaskel from the Technical University of Dresden (TUD) and Dr. Benjamin Schumm and Dr. Holger Althues from the Fraunhofer Institute for Material and Radiation Technology (IWS) awarded. This award recognizes its groundbreaking work on the development of a new procedure for the production of battery electrodes, known as Drytraec®. This innovative procedure is not only cost -efficient, but also environmentally friendly and reduces the need for toxic solvents.

The Technology Drytraec® (Dry Transfer Electrode Coating) enables the solvent -free coating of electrodes by using dry films instead of liquid chemicals. This leads to significant savings on energy costs and at the same time reduces the risk of harmful emissions associated with conventional processes. The patented method also promotes the production of powerful lithium-ion batteries (Lib), which are essential for applications in electrified vehicles and inpatient power storage.

sustainability in the battery area

The sustainability of battery technologies is becoming more and more important, especially in an environment growing environmental awareness. The demand for more efficient and inexpensive production methods is increasing because many German automobile manufacturers have started ambitious programs for electric vehicles. These require reliable and sustainable battery supply that Drytraec® can deliver. While German companies traditionally obtain battery cells from Asian manufacturers, this new technology could help reduce the dependence on imported cells.

The introduction of Drytraec® could not only reduce production costs, but also reduce environmental pollution. By avoiding toxic solvents and reducing the energy -intensive drying process, the entire manufacturing process is more environmentally friendly. These factors are of crucial importance at a time at which the entire value chain of batteries - from material to production to recycling - is under a critical view.

cooperation and further development

The close cooperation between the Tud and Fraunhofer IWS is emphasized as essential for the development of Drytraec® technology. Prof. Kaskel, who has been teaching at Tud since 2004, leads the technology field of battery technology at the Fraunhofer IWS. The first prototype system for this technology was constructed in 2013, and since then the process has continued to develop to produce high-quality electrodes in the role-to-roll process.

dr. Holger Althues emphasizes the importance of the research and development platform for industrial customers, which ranges from testing to commercial use. A leading company in the European automotive industry has already acquired licenses for technology, which paves the way to mass production.

The technical innovation could not only reduce the costs for battery production, but also revolutionize the markets, in which sustainable and inexpensive technologies are in demand. At a time when resource shortage of lithium and other ecological risks are gaining in importance, technologies such as Drytraec® can make a decisive contribution to mastering the challenges of the future.
