Openair® plasma for electromobility

Advanced battery systems frequently consist of ingenious stacks of interconnected battery cells enclosed in a common housing. Often, non-polar acid-resistant materials like modified plastics are used, both in the coating of the stacks and in the subsequent joining and sealing process of the battery housing.

Openair® plasma pretreatment (plasma activation) makes it possible to efficiently activate the surfaces non-polar plastic and composite materials that can otherwise be processed only with difficulty. This plasma activation provides the ideal conditions for reliable bonding and sealing of battery housings.

Openair® plasma technology, which is easy to integrate inline, makes an efficient process sequence possible without separate chamber systems. Openair® plasma is thus ideally suited for fully automated pretreatment in manufacturing batteries in high quantities and at high process speeds.
