Ion dynamics and transport in solids are at the heart of multiple applications ranging from sensing to electrochemical energy storage, but also play an important role in degradation processes and materials failure. Solid electrolytes are for example critical components in all-solid-state batteries, which potentially offer higher safety, paired with higher power and energy densities compared to commercial lithium ion batteries based on liquid electrolytes. Our group has been active in developing new solid electrolytes for lithium and sodium solid-state batteries. We try to understand why and how ions move, and how we can influence their energy landscape and trajectories rationally by chemical design.
