Berlin, September 4, 2023 – Atotech, a leading surface finishing brand within the Materials Solutions Division of Ƶ Instruments, will participate for the second time at The Battery Show North America, the region’s largest advanced battery event. The Battery Show brings together engineers, business leaders, top-industry companies, and innovative thinkers to discover ground-breaking products and create powerful solutions for the future.

At this show, we will present our leading surface treatment solutions for BEV, HEV and PHEV batteries. Our portfolio at the event will include corrosion protection, adhesion promotion and dedicated anti-tarnishing processes for current collectors, as well as pretreatment, anti-tarnishes and silver, nickel, and tin plating processes for connectors and busbars. We will also present our environmentally friendlier technologies for surface treatment of aluminum components within and all around the battery – thermal management system components such as heat sinks and cooling trays, as well as aluminum scroll compressors and protective shells for modules and packs. Furthermore, we will showcase solutions for highly conductive and soft magnetic electroplated layers for electromagnetic shielding and dedicated, sustainable process concepts for corrosion protection of fastening elements for battery applications.

Meet the team at booth no. 949 and discover our broad product offering for BEV, HEV and PHEV batteries.

Our product highlights include:

Cr(VI)-free anti-tarnish treatment for current collector copper foils:
