Germany-based Plasmatreat is showcasing its Openair-Plasma and PlasmaPlus technologies, designed to help manufacturers overcome EV battery production challenges including adhesion, corrosion, contact reliability and insulation.
Openair-Plasma enables dry, inline plasma treatment to prepare metals, foils and polymers for high-strength bonding and sealing without primers or wet chemicals. The result is uniform surface energy and robust adhesion across pouch, cylindrical and prismatic formats. Plasma activation creates high-energy surfaces that dramatically improve adhesion between cells. This enables structural bonds and thermally conductive joints to produce safer, stronger modules that deliver more effective heat dissipation, according to the company.
Openair-Plasma systems are equipped with PlasmaPlus for nanocoating, which allows the vaporization of a liquid additive at room temperature. The liquid can be introduced into the plasma using a carrier gas in a precisely reproducible manner.
The company’s plasma-applied AntiCorr nanocoatings protect EV battery packs from heat, salt and moisture. The transparent, ultra-thin 25-500 nm film resists acidic, alkaline and electrolyte exposure, and delivers 960 hours of salt spray protection, meeting the DIN ISO 9227 standard on aluminum die-cast alloys without corrosion or seal migration.
Plasma treatment also enables direct coating applications as an alternative to costly film wrapping.
All Plasmatreat plasma processes are free of volatile organic compounds, fully automatable and production-ready. No drying times or intermediate storage are required, enabling manufacturers to integrate them into high-volume production lines.
“Power starts at the surface—and so do failure points,” said Hardev Grewal, President and CEO at Plasmatreat North America. “Our plasma technologies are enabling OEMs and suppliers to engineer those surfaces for strength, conductivity, and long-term durability—without adding costly, chemical-intensive steps to production.”
