Why Use Plasma in Battery Manufacturing?
Surface treatment with Openair-Plasma® is based on a simple physical principle: When energy is supplied, the states of matter change. Thus, solid becomes liquid and liquid becomes gaseous. If further energy is now added to a gas, e.g. air, it is ionized and changes to the high-energy plasma state. If the ionized gas meets a surface, its properties change.
Plasma, as the fourth state of matter—besides solid, liquid, and gas—, offers numerous advantages:
- Environmentally friendly: the production is VOC-free and the technology is CO2-neutral
- Easy to integrate: easy integration into existing processes
- Quality and reliability: Improved manufacturing quality and longer battery life
- High cost-effectiveness: high process efficiency thanks to high process speed and low reject rates, use of more favourable materials thanks to flexible material selection
Plasma - Efficient, Cost-effective Solution for High-Quality and Long-Lasting Batteries
In the production of lithium-ion batteries, Openair-Plasma® ensures clean and activated surfaces by reliably removing organic contaminants and release agents and activating low-energy plastic surfaces without the need for primers or solvents. This creates optimal conditions for the long-term adhesion of adhesives, tapes, seals, and coatings, as well as for stable, automated inline processes in series production.
As an innovative alternative to other pretreatment methods, the atmospheric plasma process is low-maintenance, inline-compatible, and particularly cost-effective, as it requires only compressed air and electricity. The result is clean processes, reliable bonds, and improved performance and service life of modern battery systems.

High-Efficient Cleaning for Long-Lasting Joints
Reliable cleaning is crucial in modern battery manufacturing for safely removing organic and inorganic contaminants, release agents, and oil and grease residues from upstream production processes. HydroPlasma® uses a combination of atmospheric plasma and reactive water to clean cell, module, and housing surfaces thoroughly yet gently. It completely removes stubborn residues, creating clean, reproducible surfaces for subsequent processes such as coating, bonding, or sealing. The result is stable processes, higher adhesion quality, and a significantly reduced defect rate in series production.
Your Benefits of HydroPlasma®
- Highly effective cleaning of organic and inorganic contaminants, oils, and release agents or finger prints
- Improved process reliability through consistently clean surfaces prior to subsequent processes
- Optimal adhesion conditions for adhesives, coatings, and liquid or solid seal
- Inline-capable cleaning technology for automated, high-volume battery production
- Chemical-free cleaning process without solvents or wet chemistry
- Reduced scrap and rework rates through stable, clean production processes
Coating or Film Wrapping for Reliable Thermal Insulation
Efficient thermal management in battery manufacturing requires the uniform coating or film wrapping of battery cells. Openair-Plasma® surface treatment optimizes cell surfaces before the application of insulation films or functional coatings, ensuring consistent wetting and adhesion. This enables the consistent implementation of thermal insulation concepts and helps prevent variations and waste in mass production.
Your Benefits of Treating Battery Cells
- Improved wetting and adhesion of insulation foils and coatings on cell surfaces
- Uniform layer formation for reliable thermal insulation
- Inline-capable plasma pretreatment for automated cell production
- Chemical-free process without solvents
- Stable thermal properties and reproducible quality in series production

Reliable Cell-to-Cell/Pack Bonding
After coating or film wrapping, the adhesion of the adhesive on the surface is the decisive factor for stable cell, module, and pack structures. Whether for cell-to-cell, cell-to-pack, or the integration of the battery pack into the housing: Openair-Plasma® specifically activates the surfaces of laminated or coated cells, creating optimal conditions for durable, process-reliable and structural bonding. This sustainably enhances mechanical stability, thermal decoupling, and electrical safety.
Your Benefits for Bonding
- Maximum adhesion on film wrapped and coated surfaces
- High process reliability for cell-to-cell, cell-to-pack, and pack-to-housing bonds
- Reduced failure and rework rates in series production
- Stable mechanical and thermal bonds throughout the entire lifecycle
- Fully automatable and seamlessly integrable into inline battery assembly processes.

Selective Corrosion Protection for Metals
The AntiCorr® coating is a high-performance corrosion protection solution for battery manufacturing and e-mobility. The atmospheric plasma, added with a special precursor, selectively coats sealing and functional surfaces with an ultra-thin protective layer, reliably safeguarding battery housings from crevice corrosion and improving the adhesion of sealants. Users benefit from stable production processes, higher component quality, and a longer product life for safety-critical battery systems.
Your Benefits of AntiCorr®
- Reliable, selective corrosion protection for aluminum and magnesium battery housings
- Improved adhesion of seals and adhesives to coated sealing surfaces
- Inline integration into automated, high-volume production lines
- Reduced process and logistics costs by eliminating wet chemistry, waxing, and electroplating
