Project R-9395

Understanding the design, synthesis and properties of novel Na ion conducting electrolytes. (Research)

Sodium ion batteries are attracting great attention nowadays, e.g. for stationary energy storage. In view of safety, all solid state sodium ion batteries are highly desired. This requires highly conductive sodium ion electrolytes to be designed and synthesized. Building on existing knowledge of Li ion conducting electrolytes, with highly promising properties, the current project proposal prepares the path to sodium ion conducting eutectogels. In this framework, the synthesis and characteristics of sodium ion conducting ionogels and of sodium ion conducting liquid deep eutectic solvents will be investigated. The knowledge gained this way, will enable that finally the design, synthesis and characterization of sodium ion conducting eutectogels can be investigated. These novel materials' functionality, will be investigated on the pristine materials, but also by the integration of these electrolytes within sodium ion batteries, adding knowledge on the interaction at interfaces. As such, the project covers interesting fundamental questions in the field of inorganic synthesis, as well as physical and electrochemical properties.
