Faculty Profile of Oliver Clemens

The group works on a broad range of materials synthesis and characterization aspects. The development of novel battery systems, among them fluoride ion batteries and solid state batteries is a key topic in this aspect. But we reach out far beyond the pure battery aspects. For materials used within fluoride ion batteries as electrode materials, the intercalation and deintercalation of fluoride ions leads to a change of electronic properties, and can induce novel magnetic phenomena or superconductivity. The development of catalysts for the oxygen reduction reaction is further connected to the chemistry of oxyfluoride compounds. In addition, we target the development of materials for solid state batteries, considering their sustainability and suitability for circular economy, where we try to develop innovative separation processes to keep the materials as functional as possible. Methods used in the group comprise solid state and wet-chemical synthesis routes, thin film deposition (including pulsed laser deposition or spin coating) as well as topochemical low-temperature routes, combined with structural, electrochemical and magnetic characterization and compositional analysis.

Currently, we are looking especially for candidates with a previous background in PLD-based synthesis of oxide films and/or characterization of eptiaxially grown films via diffraction and spectroscopic methods.
