Diffusion of Ions in Solids, Battery Materials

Project: Research area

Project Details

Description

The self-diffusivity of small ions such as Li, F and Na are investigated by means of solid-state spectroscopy. Emphasis is put on analysis of underlying motional correlation functions, jump rates and activation energies to understand the relation between crystal structure and dynamic properties. Spectroscopic studies are used to shed light on micro- as well as macroscopic transport processes in crystalline as well as amorphous solids. In particular, we use solid state nuclear magnetic resonance (NMR) and conductivity spectroscopy to investigate short- as well as long-range ion dynamics in solids (nanocrystalline ceramics)
