The Chair of Production Engineering of E-Mobility Components (PEM) at RWTH Aachen University in Germany has developed a laser-based drying process for battery production.
The project, called 'Implementation of Laser Drying Processes for Economical & Ecological Lithium-Ion Battery Production' (IDEEL), combined conventional convection drying with laser drying, reducing drying times by over 60% while maintaining the same quality of results.
By retrofitting existing systems with laser modules, the process cuts the required furnace length in half, saves space and lowers operating costs by 20% to 30%.
The newly developed drying process will be incorporated into the Fraunhofer Research Institution for Battery Cell Production FFB in Münster, which serves as a development center for battery cell production in Germany and Europe.
