Design of Solid Ionic Conductors

Solid state batteries are forecasted a great future technology in energy storage for mobile and stationary applications. However, they require a targeted design of faster ionic conductors and the solid electrolyte, which is the key enabler for solid state batteries. Helmholtz Institute Münster meets this challenge in its interdisciplinary group “Design of Solid Ionic Conductors”, which cooperates closely with the WWU group of Inorganic Chemistry.

The researchers provide a deeper understanding of fundamental processes of ionic motion in solids to achieve faster conduction. The research interest scope ranges from the fundamental motion of ions in solid electrolytes to their implementation in solid state batteries.
