Electrochemical storage

Central to this topic are battery systems like lithium ion batteries as well as new systems that are still at the proof-of-concept stage of development. The HZB's focus is on metal sulfur battery systems that are considered promising technologies, in spite of the fact that their observed performance is still far from what is theoretically possible in terms of performance and energy density. Also, the number of potential charge cycles is still far too small.

Research goal

To understand the relationships between the atomic and mesoscopic structure of the materials used and the lithium sulfur system's efficiency in order to get this battery concept to the application stage.
