Lithium-ion batteries are essential components of electrically and hybrid powered vehicles, stationary energy storage systems and portable electronics. When used in electric vehicles, the biggest challenge besides increasing the range is reducing battery costs. A reduction in battery costs can be achieved by using the same materials through more efficient production and improved battery quality. This is where the project “Roll-It” comes in. In this project, the process step of drying electrodes (anode, cathode) and separators directly before they are installed into battery cells is to be investigated.
