Thin-Film Lithium-Ion Batteries
In the field of lithium storage the goal of our research is to study processes on the nanoscale in storage materials as well as complete batteries. These results are used to develop models for industrially important properties like usable capacity at high currents or fading and aging of the battery. Also thermodynamic studies of the materials are done like observing changes in the material behavior at higher temperatures.
In the field of hydrogen storage a focus is given on thin films of MgH2 and LiBH4. Study of the conversion reaction between these materials is carried out electrochemically. Investigation on the physical properties of metal hydride thin films for hydrogen or Lithium (Li) storage and ion conductivity are carried out. The transport properties and structure changes by hydrogenation and dehydrogenation will also be studied with atomic resolution by using atom probe tomography.
