Electric mobility presents manufacturers worldwide with growing challenges: fluctuating surface conditions of incoming components, increasing cycle times, and continuous 24/7 production with maximum process reliability, all while quality requirements continue to rise. Especially in the later stages of the value chain, even the smallest deviations can lead to costly scrap. How can stable processes, high yields, and long-lasting battery systems be ensured under these conditions?
This PlasmaTalk by Lukas Buske provides answers with the latest technologies and applications across the entire battery production process.
The presentation begins with an overview of innovative plasma applications across the entire EV battery value chain, from material pretreatment to final assembly processes. This highlights where plasma offers the greatest impact on process reliability, yield, and quality within the process chain. The presentation is rounded out with the latest technology and process updates across the entire battery production chain. It demonstrates how the targeted use of plasma enables solutions that deliver the highest quality, process stability, and efficiency, even under the most demanding production conditions. At the same time, it highlights how scrap risks can be reduced in late stages of the value chain and how stable 24/7 production can be ensured.
In this PlasmaTalk, Lukas Buske will address the following topics:
Plasma treatment of current collector foils, specifically for oxide reduction
Focus on cleaning, activation, and targeted oxide reduction of current collector foils. These steps are crucial for improved wetting and adhesion of the electrolyte. Compared to conventional corona technology, plasma enables more homogeneous, stable, and reproducible surface modification, while offering greater process control and efficiency. This leads to more stable electrolyte wetting, less variation, and more reproducible results, even at high cycle rates.
Removal of electrolyte residues using HydroPlasma®
Gentle yet effective cleaning of sensitive battery areas, inline, selectively, and without additional chemicals. This increases process reliability in sensitive areas, reduces rework, and lowers the risk posed by residues, without the need for additional chemical cleaning processes.
PlasmaPlus® coatings for long-term stable bonds
PlasmaPlus® coatings for long-term stable adhesion enhancement. Applications range from the optimization of bonding processes to improved adhesion of solid-state slurries, a key component for future battery generations. This supports longer-lasting, more stable bonds and robust adhesion, also with a view to future cell and material concepts.
