Ionic liquids for Nano-structuration and Surface functionalization of Electrode Materials – Nano-INSPIRE

Nanosizing electrode materials permit greatly improved ionic and electronic conductivities. Nevertheless, some challenges associated to the reactivity of nanomaterials remain due to their high specific surface area, which leads to parasitic and often irreversible reactions and strong interaction with electrolytes. To face these defies, Nano-INSPIRE is a fundamental project aiming at developing and studying the use of ionic liquids (ILs) to control the nano-structuration and to functionalize electrode nanomaterials surface in order to stabilize it. This project focuses on the stability of ILs coating layer in highly concentrated aqueous electrolyte depending on the ILs chemical composition and on the comprehension of its influence on the electrochemical performances. Sodium metal phosphate, which are among the most promising electrode materials for sodium-ion aqueous systems, will be used as reference materials.
