Research & Skills

I am a physicist with a background in preparation and characterization of inorganic semiconductor nanostructures and polymers using neutron, X-ray, infrared and microscopy techniques. At TUM, I focus on Li-ion battery research and perform operando and post-mortem evaluations of electrode microstructure and morphology, as well as monitor Li diffusion kinetics within cells to understand the fundamental processes, so that safe Li-ion batteries with higher energy density and longer lifetime can be realized.

Materials:

  • Anodes (graphites, silicon-graphite composites, lithium metal, lithium titanate)
  • Cathodes (layered Oxides, olivine phosphates)
  • Electrolytes (carbonate electrolytes, polymer electrolytes, glassy electrolytes)

Applied Methods:

  • neutron and x-ray reflectivity
  • neutron and x-ray diffraction
  • small-angle neutron and x-ray scattering
  • depth resolved grazing incidence small-angle neutron scattering
  • neutron depth profiling
  • quasi-elastic neutron scattering
