Plasmatreat, the world's leading developer and manufacturer of atmospheric pressure plasma technology, is presenting its innovative surface treatment solutions at the Battery Show Europe 2025 in Stuttgart, Germany, in hall 8, booth C10. With Openair-Plasma® and PlasmaPlus®, Plasmatreat GmbH, headquartered in Steinhagen, Germany, enables improved adhesion, environmentally friendly corrosion protection and more efficient production processes - key factors to produce high-performance, long-lasting and sustainable batteries.
Sustainable and inline-capable plasma technology for battery production
Batteries, whether prismatic, cylindrical or pouch cells, must nowadays be powerful, durable and, ideally, sustainable. Plasmatreat's Openair-Plasma® and PlasmaPlus® are environmentally friendly alternatives to conventional chemical pre-treatment processes. They offer ultra-fine cleaning, surface activation and functionalized nano-coatings - all in a dry inline process that requires only compressed air and electricity.

By removing impurities, increasing surface energy and improving adhesion, Plasmatreat's plasma solutions support critical steps in battery manufacturing, such as
- Cell-to-cell bonding: Plasma activation improves adhesion for structural bonds and thermally conductive bonded joints.
- Corrosion protection: PlasmaPlus® AntiCorr® coatings provide protection against infiltration corrosion for battery housings, terminals and other critical components.
- Wire bonding and contact cleaning: Openair-Plasma® ensures reliable electrical connections by removing residue from battery terminals.
- Innovative insulation processes: Plasma treatment enables direct coating applications as an alternative to costly film wrapping.
Live demonstrations: Plasma technology for key battery applications
At booth C10 in hall 8, Plasmatreat will present a series of live demonstrations showing the impact of plasma surface treatment on battery production. One highlight will be the state-of-the-art Plasma Treatment Unit (PTU), featuring advanced nozzle technology for Openair-Plasma® activation and cleaning, as well as PlasmaPlus® coating for automated, selective and reliable surface treatment. Whether cleaning batteries before applying insulating film or coating, activating already insulated batteries before bonding, or applying functional coating, e.g. AntiCorr®, against infiltration corrosion.

Plasmatreat will be placing a special focus on the cleaning of battery cells before electrical insulation, whether with PET film or coating, at its trade fair booth: Visitors will be able to experience live how plasma activation improves the adhesion of PET films and PET coatings, thus ensuring optimum insulation performance. For long-term stable corrosion protection, Plasmatreat will also be demonstrating its AntiCorr® coating for complete battery housings, which will be validated with AntiCorr® test fluids. The AntiCorr® process has already been extensively tested and has successfully passed the standard climatic tests and salt spray tests, such as the PV1209 or the MeKo-S test.
Another special feature on booth C10 in hall 8 is the SCARA Janome robot system, on which the plasma experts will be demonstrating the precise plasma treatment of both cylindrical and prismatic battery cells. Equipped with various nozzle configurations, the system demonstrates the flexibility of Openair-Plasma® technology for different battery geometries and materials. For cylindrical cells, the plasma treatment ensures ultra-fine cleaning of the battery contacts prior to wire bonding, which improves the electrical connection and reliability. For prismatic cells, plasma activation optimizes the surface adhesion for subsequent coating, film or bonding processes.
The range of different systems and equipment highlights Plasmatreat's industrial-grade plasma solutions designed for seamless integration into high-speed in-line manufacturing environments in the automotive and energy storage industries.
Visitors to the Plasmatreat booth C10 in Hall 8 are invited to bring their own materials and test the plasma effect live at Plasmatreat.
