Different lithium-sulfur pouch cell dimensions

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


Li-S- and Na-S-prototype cells

Development of prototype cells with high energy densities and low material costs

  • lithium-sulfur battery cells (specific energy up to 360 Wh/kg)
  • sodium-sulfur battery cells (stable operation at room temperature)
