Materials Interface ELectrochemistry (Team MIEL)


The scientific project of the team are based on material science  and electrochemistry and are largely focused on applications concerning the storage and conversion of energy: fuel cells (PEMFC, SOFC, PCFC), batteries (lithium-polymer, lithium-ion, lithium-sulfur, sodium-ion, magnesium), high-temperature electrolysers. The research activities of the team are based on common descriptors that concern both electrolytes and electrodes, as well as their interfaces.

The objectives of these studies are:

- Design of new materials and the development of original and optimized microstructures to overcome scientific and technological barriers

- Understanding of the physico-chemical properties, as a function of structural, microstructural, functional, thermodynamic and kinetic parameters.

In situ and operando sudies of electrochemical systems under
controlled atmosphere and temperature by coupled techniques (Raman, DRX, tomography ...) and electrochemistry and the development of Raman imaging.
