IWS scientists develop cost-effective solutions along the process chain "manufacturing of battery cells".


Electrode packaging

An automated laser cutting system has been developed for electrode packaging from coil.

  • flexible electrode dimensions
  • automated removal of electrode blanks
  • roll-to-roll
  • local dry air supply


Cell assembly process

Development of automated cell manufacturing:

  • set-up of pouch cells stacked from individual layers (- single layer stacking)
  • continuous separator packaging
  • tab welding
  • local dry air supply


Prototype cell design and evaluation

Lithium-ion, lithium-sulfur and solid-state battery cells

  • customized design of multilayer pouch cells
  • cell tests under defined conditions (temperature and pressure)
