Young investigator group „Anion and cation conducting electrolytes for solid state batteries“

 

The increasing utilization of renewable energy sources and the advance of electro mobility demand the provision of suitable storage technology. The Helmholtz-Institut Münster brings together scientists from Münster University, Forschungszentrum Jülich and RWTH Aachen University to develop and improve batteries for these applications.

The young investigator group “Anion and cation conducting electrolytes for solid state batteries” in Aachen focuses on the investigation and development of electrolytes for solid state batteries. We are especially interested in battery concepts utilizing oxygen ion conductors like the rechargeable oxide battery (ROB). This new concept features long term stability, high energy density and low material cost. In addition, we are interested in the all-solid-state Li-ion battery.

In our research, we combine theoretical and experimental methods to gain insight into the properties of solid state electrolytes and develop new materials.
