September 6th to 8th, 2022
More than 100 battery experts met in Ulm from September 6th to 8th to discuss the latest developments in batteries that do not require lithium. The 4. “International Symposium on Magnesium Batteries”, MagBatt4 for short, has been established in Ulm since 2016 and attracts researchers from all over the world. This time, the program was expanded to multivalent batteries in addition to magnesium batteries and was discussed in a total of 37 lectures and one poster session.
Multivalent batteries are based on magnesium, calcium, aluminum and zinc. They offer an interesting alternative in terms of the amount of energy that can be supplied, safety, manufacturing and disposal costs and limited environmental impact. The development of completely new battery chemistries is a major challenge. In particular, the high cationic conductivity of multivalent cations such as Mg2+ and Ca2+, Zn2+ or Al3+ is difficult to achieve at ambient temperatures in solid electrolytes. Various phenomena have been discovered that can improve conductivity, such as e.g., nanoparticulate additives, nano-encapsulation, stabilization of disordered polymorphs with high dynamics in the solid state, etc. Development of electrodes compatible with high-performance electrolytes is also challenging.
