Biography :

As a chemical engineer, I did a thesis and then a post-doc in the field of polymer and composite materials, working on adhesion and bonding issues. In 2001, I joined Polytech Nantes, the engineering school of the University of Nantes, in the materials science department, to teach polymer and composite materials, and bonding; and the “lithium batteries” group in the ST2E (Stockage et Transformation Electrochimiques de l’Energie) team, headed by D. Guyomard, at the Institut des Matériaux Jean Rouxel (IMN). At Polytech Nantes, I was responsible for the 4th year of the Materials department for 10 years (2015-25). At IMN, I have been co-leader of the ST2E team’s battery group since 2009. As soon as I arrived at IMN, I initiated a research theme that was new to IMN and little developed in the national academic community: the formulation of lithium battery electrodes. Today, I’m one of the international leaders in this field of research, which is crucial for optimizing the electrochemical performance of industrial batteries. This has led me to work with numerous companies, to lead two ANR projects (CALICE then PEPITE in 2010-13 and 2015-19), and to be in charge for IMN of various European projects (EUROLIION in 2011-15 and DESTINY in 2020-25 and 2026-30), and the TOURS 2015 project (2015-19) selected as part of the “Nanoelectronics n°1” call for projects of the Investissements d’Avenir. From 2014, I was involved in setting up, then leading and steering the joint laboratory with ARMOR, which led to the creation of a battery prototyping platform at IMN and Nantes University.
