A book on "Sodium-Ion Batteries" - Finally!

So happy to announce that the book on "Sodium-Ion Batteries" is finally in press.
20 chapters and more than 700 pages on materials, characterization and technology of Na-ion batteries. The book was written by many researchers from the Na-ion battery research community, so big thanks to everyone who contributed to it.

Joint BMBF project on solid-state batteries starts.

The 3-years project KAROFEST focuses on developing Lithium solid-state batteries with sulfides as cathode active materials (CAMs). The project is coordinated by Humboldt University Berlin (Adelhelm group) and includes the partners University Giessen (Janek group) and University Münster (Zeier group).

Prof. Adelhelm becomes member of the BMBF-Beirat Batterieforschung Deutschland
