The group of Chemical Materials Synthesis under the lead of Prof. Dr. Clemens is currently developing new materials for energy storage applications, including active electrode materials for fluoride ion batteries, ion conductors for solid state batteries, and catalytically active materials for solid oxide fuel cells and protonic ceramic fuel cells. More recently, we also consider recycling strategies for all solid state batteries.


Many of these materials have complementary functional properties, such as magnetic ordering or superconductivity. Coupling of such properties to electrochemical reactions opens a pathway to tunable functional properties, interesting for both, energy storage and information technologies.


The compounds of our interest range from perovskites and their vacancy ordered derivates, materials with Ruddlesden-Popper type structure and garnet based solid electrolytes. A strong focus is set on materials synthesis and topochemical modification, e. g. via hydration or fluorination routes. Thus a broad range of techniques are being explored, including solid state reactions, sol-gel synthesis, reactive milling, hydrothermal reactions, spray pyrolysis approaches, and thin film synthesis, which then are coupled with techniques such as polymer based fluorination routes.


Deep understanding of the materials requires the use of various techniques available in our group, among them XRD, electrochemical characterization, and impedance spectroscopy. Such measurements are complemented with other techniques accessible after application (neutron diffraction, X-ray absorption spectroscopy), or in co-operation with other groups (Raman, IR, XPS, SQUID magnetometry, TEM).


If you got interested on working in our group or doing a student project, please contact Prof. Dr. Clemens for further information. We’re always delighted to host international researchers from around the world!
