This pioneering solution is unique in the industry and offers superior corrosion protection as well as improved performance of copper foils used in electric vehicle battery packs, energy generation and storage systems, notes a press release from the company.The new Chemetall Gardolene® D is fully compliant with the European Union's new Battery Regulation (EU 2023/1542), which mandates carbon footprint declarations, digital battery passports, and strict limits on hazardous substances. Gardolene® D directly enables superior battery performance in the end product. A key feature of the new Gardolene® D for copper foils is the improvement of surface energy, which enables better adhesion of anode active materials and reduces electrical resistivity, which results in higher battery efficiency.They thereby significantly improve the eco-friendliness of the entire battery value chain in a way no other products can. The new solutions are compatible with existing equipment and suitable for both electro-deposited and rolled annealed copper foil substrates used in the production of batteries for electric vehicles and a wide range of other energy generation and storage applications. This innovative technology delivers superior heat and corrosion resistance compared to existing solutions.Our dedicated research and technology teams across the globe have intensively analyzed available solutions and market needs. Based on our comprehensive expertise in surface treatment and close exchange with our customers, we were able to push boundaries and develop this one-of-a-kind global solution for copper foil pretreatment. It ensures stable copper foil properties, improved electrode conductivity, and supports manufacturers in meeting evolving regulatory and sustainability requirements compared to standard passivation processes,” says Arjan Termaten, Head of Global Technology at Chemetall.
