Abstract:
Solid electrolytes are generating considerable interest for solid-state batteries to address safety and performance issues. It is clear that a complete understanding of such materials requires greater fundamental knowledge of their underlying ion transport and interfacial properties. In particular, grain boundary effects on ion transport are not fully understood at the atomic scale. This presentation will highlight recent studies in this area, including the influence of grain boundaries on Li-ion transport in the Li-rich anti-perovskite Li3OCl and the different effects of grain boundaries in a sulphide (Na3PS4) solid electrolyte compared to an oxide (Na3PO4) solid electrolyte. A combination of advanced materials modelling techniques has been utilised to gain new insights into these complex materials, which are valuable in developing strategies to optimise their electrolyte properties.
