Investigation of lattice dynamics in promising solid sodium electrolytes

DOI

All solid-state sodium ion batteries are potential low-cost alternatives to lithium ion batteries, especially for static and large-scale energy storage systems. The shift from liquid to solid electrolytes also promises major gains in battery safety. The critical challenge for all solid-state batteries is the lack of high conductivity electrolytes. In order to improve existing materials and develop new ones, we require not only a detailed knowledge of the structural properties of these materials, but also of the conduction mechanisms at the atomic scale. The proposed experiment aims to investigate the lattice dynamics in two promising solid-state electrolyte systems (layered Na2M2TeO6 (M = Zn, Mg) with 2D diffusion; and glass ceramic 3D Na ion conductors based on Na3PS4) to elucidate the influence of different doping strategies onto bonding and dynamics in these compounds.
