The advent of solid state batteries has spawned increased interest recently in lithium conducting solid electrolytes. However, many open questions remain when trying to optimize electrolytes and understand solid state battery chemistries.

In this presentation, learn:

  • How an understanding of the structure-transport properties of the lithium argyrodites Li6PS5X can help tailor the ionic conductivity.
  • That an anion site-disorder and anionic charge inhomogeneities are important and that tailoring that disorder leads to improvements of the conductivity.
  • It is not only important to find fast ionic conductors, but that fast ionic conduction is paramount within solid state battery composites.
  • Measuring the effective ionic transport in cathode composites provides an avenue to explore transport and stability limitations that in turn provide better criteria for solid state battery performance.
  • We explore the current focus of halide-based ionic conductors in solid state batteries and discuss stability limitations in solid state battery cells at the anode as well as the cathode composites.

Wolfgang Zeier was appointed Professor of Inorganic Chemistry at the Westfälische Wilhelms-Universität Münster in 2020. He also heads the Ionics in Energy Storage Department at the Helmholtz-Institut Münster. His research interests encompass the fundamental structure-to-property relationships in solids, with a focus on thermoelectric and ion-conducting materials, as well as solid-solid interfacial chemistry for all-solid-state batteries. Professor Zeier received his PhD in Inorganic Chemistry in 2013 from Universität Mainz. After postdocs at the University of Southern California, California Institute of Technology, and Northwestern University, he was appointed group leader at Justus-Liebig-Universität Giessen, within the framework of an Emmy-Noether research group.
