Kampf TechSlitter for battery cathode foil goes into production at Gränges, Sweden

Battery foil must meet the highest quality criteria. This includes the process of slitting and winding. The slitting process developed by KAMPF for slitting battery foil meets the high-quality requirements and sets new standards. 

Gränges, developer of lighter, smarter and more sustainable aluminium products and solutions stands for the highest quality. Gränges has ambitious plans for the global market launch of battery cathode foils and is pushing ahead in big steps: Asia in 2022, Europe in 2023 and the Americas in 2024. A recent agreement with a leading global battery manufacturer claims the originally planned production capacity in Europe. To keep up the fast pace, Gränges is now investing in doubling its capacity in Finspång, Sweden, to meet the growing demand for battery components in Europe. This new capacity is scheduled to come online as early as 2025. 

To meet the high demands of battery manufacturers, Gränges relies on its highly specialised employees and high-tech equipment in the production process. The slitting and winding of the cathode foil will be performed on a Kampf TechSlitter. This machine concept is based on many years of experience in the field of machines for aluminium foil processing and anode/cathode technologies. The solution provider from Wiehl/Germany is a leader in the field of slitting and winding technology and introduced machines for modern energy concepts early on, which are in production worldwide. The TechSlitter enables rewind diameters up to 800 mm and slitting widths from 200 mm. With a slitting process that slit the foil almost particle-free. The machine can be equipped with all measuring systems required for battery foil production. It goes without saying that a KAMPF machine is a solution that would be thought of in the age of Industry 4.0. This machine meets all the necessary requirements and is the perfect machine for processing battery foil and fulfils the high demands of Gränges and their customers. 

Kampf's high-performance machines will match this speed and their mature concept is based on more than 10 years in the field of the battery technology and more than 40 years in the aluminium industry. Both companies focus on sustainability and the responsible use of resources in their business strategies. 

At the beginning of March, the first Kampf TechSlitter successfully went into production in Finspång - as planned and executed jointly by the project teams.
