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)
