Start your accelerator tour - the Long Night of Science in a different way

Due to corona restrictions, unfortunately there will be no Long Night of Science this year. This is not only a pity for all those interested in science, but also for us! We look forward to it every year when many people come to us, asking us questions or being amazed by the huge facilities and laboratories in which we do our research. To make sure that the long night doesn't fall flat, we take you on a virtual journey through our accelerator BESSY II.
It starts on June 6 at 5 pm.

- Innovative battery electrode made from tin foamMetal-based electrodes in lithium-ion batteries promise significantly higher capacities than conventional graphite electrodes. Unfortunately, they degrade due to mechanical stress during charging and discharging cycles. A team at HZB has now shown that a highly porous tin foam is much better at absorbing mechanical stress during charging cycles. This makes tin foam an interesting material for lithium batteries.
- BESSY II: Building block of the catalyst for oxygen formation in photosynthesis reproducedIn a small manganese oxide cluster, teams from HZB and HU Berlin have discovered a particularly exciting compound: two high spin manganese centres in two very different oxidation states and. This complex is the simplest model of a catalyst that occurs as a slightly larger cluster in natural photosynthesis, where it enables the formation of molecular oxygen. The discovery is considered an important step towards a complete understanding of photosynthesis.
- Lithium-sulphur pouch cells investigated at BESSY IIA team from HZB and the Fraunhofer Institute for Material and Beam Technology (IWS) in Dresden has gained new insights into lithium-sulphur pouch cells at the BAMline of BESSY II. Supplemented by analyses in the HZB imaging laboratory and further measurements, a new picture emerges of processes that limit the performance and lifespan of this industrially relevant battery type. The study has been published in the prestigious journal Advanced Energy Materials.
