Research Interests

Our current research interests in the field of solid-state materials science are the synthesis of single crystals, (nanostructured) ceramics, and composite ceramic/polymer materials, their characterization in terms of structure-property relationships as well as their implementation in energy storage and conversion devices, including all solid-state batteries.

In particular, we focuses on solid-to-solid interfaces. Furthermore, we are interested in the structural degradation of ceramic materials in humidity and air and its impact on dynamics and stability.

We use a large portfolio oftechniques, such as X-ray and neutron diffraction, Raman spectroscopy in combination with electrochemical techniques, such as impedance spectroscopy, cyclic voltammetry, and galvanostatic cycling, as well as electron microscopy, using, e.g., HRTEM and SEM.
