Synthesis of LiNbO3 nanoparticles for application in Li-All-Solid-State batteries

All-Solid-State Batteries give high potential for future energy sources in electromobility. With their solid electrolyte these cells have a higher energy density and improved safety than regular Li-Ion battery cells. For the technical realization there is high demand for research and development. more

Improvement of cathode Composite granules for All-Solid-State batteries

With an optimized design of the surface of the cathode composites, the processability of intermediate products ca be improved. Additionaly, the realization of nanoparticular thin films can increase the stability against moisture
as well as the storability, so that the ionic and electrical conductivity is maintained. more

Synthesis of nanoparticles and following fractionation by preparative gel electrophoresis

Monodisperse nanoparticles with uniform properties regarding size and morphology are essential already today for optical (plasmonic) applications, self-assembly processes etc.
On the focus of recent research, the fractionation of synthesized nanoparticles is investigated (s. Abb. 1). For this purpose the gel electrophoresis should be used in this project, which can separate particles due to different electrophoretic mobilities µE. more

The Future of Electromobility – All-solid-state batteries

All Solid state batteries (ASS) offer the potential for future energy sources in electromobility. They typically having a solid electrolyte. Through the use of solid electrolytes, all Solid State batteries provide higher energy densities while improving safety. There is a current need for research and development for technical feasibility.

Synthesis, characterization and functionalization of quantum dots

This work will focus around the ‘bottom-up’ synthesis of monodisperse quantum dots at different sizes as well as their characterization. The methods of choice will be absorption and fluorescence spectroscopy, dynamic light scattering (DLS), small angle X-ray scattering (SAXS) and transmission electron microscopy (TEM).
The main objective will be to address the influence of the immediate surroundings, such as ligands or solvents, onto each individual method and their correlation. more
