Plasma supports mobility-related changes in the battery industry

Explore the remarkable capabilities of this eco-friendly and highly efficient technology live at Battery Show 2024!

Visit us at our booth C10 in hall 8 and be impressed by the potential of plasma treatment as a pretreatment for all types of batteries.

Changing mobility means that demand for high-powered EV batteries is growing rapidly. New production lines are being built all over the world that are geared to mass production. When looking for the optimal battery, range and fast charging are important criteria. To achieve this, the battery needs to be well insulated, structurally bonded and thermally conductive.

This is where Plasmatreat comes in: plasma technology is the key technology for microfine cleaning, surface activation and nano-coating of a wide range of materials. This technology supports various production steps and offers a number of advantages over other processes.
Excellent use can be made of this in the various steps of high-performance battery manufacturing and can be achieved with Plasmatreat's systems and equipment for inline plasma activation to reliable bond and seal housings or for cleaning and coating of batteries.

Why should you take a closer look at plasma technology?

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: Our 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

pretreatment battery cell

Pretreatment and cleaning of various battery cells enable painting with 100% UV paint together with coating system manufacturer Venjakob

Discover how a Scara robot is used to precision clean various metal battery cells as a pre-treatment for painting with 100% UV paint instead of a complex film coating. Before coating, the battery cells are ultrafine cleaned with Openair-Plasma® in order to achieve a clean surface with perfect adhesion properties for the coating process.
Thanks to this application, the foiling of the battery cell can be completely and reliably replaced by painting, resulting in cost and time savings and a higher quality of the final products.

Reducing test time with AntiCorr® Test Fluids

Would you like to find out how successful your anti-corrosion coatings on your products have been? For the first time at the Battery Show, we will be presenting our new AntiCorr® test fluids with anti-corrosion coatings on complete battery housings - with this innovative method, copper sulphate and a highly acidic and corrosive liquid are applied to the surface as drops which transforms the assessment process and provides efficiency without compromising accuracy.

Our plasma expert Lukas Buske explains what we will be presenting to you!

How does plasma work?

Openair-Plasma® is generated with electricity and compressed air and is even CO2-neutral when green energy is used. All plasma processes are solvent-free, contribute to the environmental balance and can be integrated into existing production lines.Dry surface treatment with Openair-Plasma® can be carried out in a fully automated process, as an environmentally friendly alternative to harmful chemical processes. Here, the need for additional pre-treatments with chemical primers is eliminated during the activation and fine cleaning of various surfaces prior to bonding, coating, painting, or sealing. Modern, solvent-free or water-based adhesives, paints, and varnishes can then be used. This significantly reduces the emission of VOCs in production.

plasma treatment of cylindrical cells

Plasma in battery manufacturing

Plasma technology is used for all kinds of batteries: prismatic, cylindrical and pouch cells. The areas of application are extremely wide. For example, optimization of electrical insulation can be achieved via plasma cleaning prior to coating or the covering of individual cells with PET film. In cell-to-cell bonding, meaning adhesion of individual cells to the battery module, plasma treatment activates the cell surfaces after application of the coating or the film covering, thereby improving adhesion and thus thermal conductivity. The adhesiveness of structural bonding in a battery module, e.g. of the side walls, can be increased through plasma treatment of the components.


Process automation with battery standard equipment

At the Battery Show 2024, we will be presenting plasma treatment for various battery types and sizes in a special system that can be easily integrated into the production line: The Plasma Treatment Unit (PTU) equipped with a robot and our system components. Our generator, different jets (for example PFW10, RD1004, RD2010SI) and our Openair-Plasma® process monitoring PCU illustrate the extensive product portfolio. With a special focus on the Plasma Control Unit (PCU), we will show you how comprehensive process monitoring and control can meet high requirements and support digitalised production processes.


Inline contact angle measurement in the Plasma Treatment Unit

A Plasma Treatment Unit will not only be on display at our booth, but also at the booth of our partner Krüss in hall 9, booth B50. There we will present an innovation: the integrated and automated contact angle measurement of an Ayriis instrument from Krüss in a PTU from Plasmatreat. The automated and robot-controlled measurement of the contact angle before and after treatment eliminates time-consuming handling. The integration of the Ayriis into the PTU enables continuous quality control of wettability and provides accurate 3D contact angle measurements in seconds.

With the wide range of different nozzles and generators and the different handling systems we use for plasma treatment, we can offer our customers exactly the solution they need for their particular process and production environment."

• Increasing the stacking factor increases the capacity by up to 20%
• Higher cycle stability due to improved mechanical resistance
• Enables short-term higher discharging currents

Benefits for LIB production

The use of Openair-Plasma® technology in the production
process optimizes workflows:
• Significant increase in energy density

• Significant cost reduction
• Substantial increase in LIB cycle stability
• Approved adhesion of the active material
• Increased battery efficiency

The potential of PlasmaPlus® coating

Active corrosion protection can be applied to the sealing surface of the battery housing with the aid of PlasmaPlus® technology. Climatic loads and positional constraints increase the requirements placed on the battery housing. In the electromobility sector, a media-tight seal is critical.

We are ready for your challenge!

You can experience a compact introduction to atmospheric plasma technology at booth C10 in hall 8. Discover various equipment and systems for demonstrating Openair-Plasma® surface treatment: using a Scara Janome, we will demonstrate the treatment of a prismatic cell prior to painting and subsequent stacking, focusing on the different handling options - whether inline system, robotic jet guidance or robotic component guidance.

On our Livetable we will show you the benefits of cleaning battery cells before the electrical isolation and you will learn about the activation of PET films or PET spray coatings. Also you have the chance to test the materials you have brought along for their suitability for plasma treatment.

Our atmospheric plasma technology can be a game changer with regards to adhesion characteristics, substrate substitutes or functionalization of surfaces.
