Laser Setup - PR753312-3470-W.
1 piece laser setup for cell contacting and battery module formation
At the Fraunhofer IGCV in Augsburg, the demonstration of manufacturing processes of lithium-ion, sodium-ion and solid-state battery cells in small quantities for research and development projects is planned. The entire process chain of battery production is to be presented. Starting with electrode production with the trades of mixing, coating and calendering to the abuse testing of finished battery cells. The assembly of the cells is also a central process step. Here, various process steps in cell and module assembly are to be implemented with a suitable laser setup.
The laser setup is planned as part of the manufacturing process of both individual battery cells and entire modules. A central criterion here is the flexibility of the system, i.e. a wide variety of formats, sizes and cell technologies should be covered by one system. The following process steps are to be taken over by the laser setup either promptly or in perspective:
• Welding of prismatic and cylindrical battery cell housings
• In-cell contacting of different battery cell types
• Format-independent contacting of individual battery cells to form entire modules
• Separation and structuring of battery electrodes
• Cleaning of contact surfaces on battery cells
The laser setup will initially consist of two laser beam sources that emit light in the infrared wavelength range. One source each is to be available at laser process modules 1 and 2. In addition, a possibility to integrate another laser beam source into module 2 is to be provided. The choice of laser beam sources must correlate with the optics.
