High-performance batteries: inline plasma activation to reliably bond and seal housings

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.
 Plasma activation 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.

Advantages of Openair® plasma pretreatment during bonding and sealing of battery housings:

  • Extremely high degree of activation, incorporation of up to 30% reactive groups (for example, oxygen functionalities)
  • High process speed
  • Optimal process control
  • Simple inline integration
