Structural chemistry of ionic conductors
Ionic conductors are used in many applications such as fuel cells and batteries, and a high ionic conductivity is usually desired. We aim to understand the motion of ions (e.g. Li+) within a material’s structure and employ synthetic strategies to increase the diffusion pathways and ionic conductivity. The materials we study are oxides, phosphates, sulfides and thio-phosphate lithium ion conductors.
