Our offer

The cell assembly line enables the production of lithium-ion battery pouch cells. The system includes all process steps: separation, deep drawing, z-folding, ultrasonic welding, heat sealing and electrolyte filling. The production process can be precisely recorded by recording numerous process parameters. This enables comprehensive validation of the production of new battery technologies.

Data

  • Illustration of the entire process chain for the construction of a lithium-ion pouch cell:
  • Separation of the electrodes using a punching tool
  • Merging of the electrodes and the separator in the Z-folding process with more than 60
  • Welding of the arresters to the external contact lug in ultrasonic welding process
  • Sealing the pouch housing
  • Fully automatic filling of the pouch cell with electrolytes in a separate reaction chamber
  • High flexibility in the number of sheets to be stacked
  • High process accuracy due to fully automatic stacking process
  • Accelerated wetting of the separator with electrolytes by vacuum impact in the reaction chamber
