Research topic

My research deals with silicon nanostructures as alternative negative electrode in state-of-the-art Li – ion and future Li – S batteries. In particular, the development of economical synthesis strategies and the investigation of structural changes in silicon electrodes after cycling in different cell set-ups are of interest. Typical characterization methods in my work involve electrochemical analysis, X-Ray diffraction, electron microscopy (SEM / TEM) and X-Ray photoelectron spectroscopy.


The project is part of the WING-Zentrum: Batterie - Mobil in Sachsen (BamoSa) and finanicially supported by the Bundesministerium für Bildung und Forschung.
