Title: Na-dynamics in NZTO, a possible solid-state electrolyte
Affiliation: University of Oslo
Abstract
Improving a specific material property requires a thorough understanding of its limiting factors. To compete with the existing liquid electrolytes, solid state electrolytes require materials with an exceptional ion conductivity. Layered hexagonal P2-type materials have been investigated as candidates for both cathode and electrolyte of solid-state batteries.
To thoroughly understand the sodium dynamics, nuclear magnetic resistance (NMR) is employed. It probes the local environment of each Na-position in the electrolyte candidate material Na3Zn2SbO6, at different temperatures. The preliminary results show the transition of one position from inactive to active in the Na conduction, making this a probable limiting factor of ion conduction in this material. These results also display the strength of NMR as a tool to understand Na-dynamics.
