DAISY-BAT

DAISY-BAT

The DArmstadt's Integrated SYstem for BATtery research is a collaboration platform of the Surface Science Lab (Prof. Hofmann) and the group Advanced Thin Film Technology (Prof. Alff). DAISY-BAT offers unique possibilities for well-defined vacuum preparation of thin film and intercalation battery components (anode, cathode, electrolyte) and complete thin film cells and their characterization. Next to Chemical Vapor Synthesis (CVS), the system hosts Pulsed Laser Deposition (PLD) and different sputtering chambers for anode, cathode, and electrolyte materials. X-ray and UV photoemission spectroscopies are used for sample characterization. Interface experiments are carried out to investigate the electrode-electrolyte interactions as well as operando experiments on tailor-made thin film batteries. The latter enable studying the charging and discharging steps live with photoemission spectroscopy.
