Innovations for the battery of the future – this is the research focus of the Surface Chemistry Technology field, which is developing new concepts for the entire process chain of battery cell production. Structure-property relationships for new materials in battery cells are being researched and efficient as well as cost- and resource-saving production processes are being developed. In addition to the further development of current lithium-ion technology, the focus is also on innovative storage concepts such as the lithium-sulfur and solid-state battery.
A central field of research and development is novel chemical coating processes. The dry transfer electrode coating process DRYtraec® developed at Fraunhofer IWS enables the solvent-free, environmentally friendly and cost-efficient production of battery electrodes. Innovative process solutions are being developed for lithium metal batteries, from the production of thin lithium layers to automated cell assembly.
Another focus is on customized solutions for gas and particle filtration of harmful substances. Requirements for the design of selective and efficient filter systems arise in a wide variety of production environments, including during battery production and recycling.
