Dr. Hab.
Mikaël Cugnet earned his master's degree in 2004 and his PhD in automation in 2008 from the University of Bordeaux. He was granted his accreditation to supervise research (Habilitation à Diriger des Recherches, or HDR) in 2020 in electrochemistry at Grenoble Alpes University. His PhD research, conducted from 2005 to 2008 on the Integration of aging into the management of a lead-acid automotive battery, was funded by PSA Peugeot Citroën and supervised by Alain Oustaloup and Jean-Marie Tarascon. From 2008 to 2010, he completed a postdoctorate, supervised by Bor Yann Liaw, at the Hawaii Natural Energy Institute.
In 2010, he began his tenure as a research engineer at the CEA, where, as a battery specialist, he was tasked with setting up and managing research projects with academic and industrial partners. He earned the titles of CEA Expert in 2017 and CEA Senior Expert in 2023. He also won a gold medal at the Alstom I Nove You™ Awards in 2020.
He has been a member of the Electrochemical Society since 2008 and an expert for the European Commission since 2016.

His research focuses on modeling and diagnosing the condition of Pb, Ni-Cd, Ni-MH, Na-MCl2, Li-ion, and Na-ion batteries.
How can you design batteries with the lowest possible impact on the environment? Well, together with Laboratoire G-SCOP, CEA researchers combined LCA with parametric models. This unprecedented method allows them to quantify the impact of design choices on a battery’s environmental impact, including its lifetime.
By combining X-ray diffraction and small angle scattering at the ESRF, electrochemical analysis and gas detection, CEA researchers have managed to track the degradation of an overcharged Li-ion battery in real time. This breakthrough brings great opportunities, including the ability to identify the optimal operating range, refine aging models, and improve post-production quality models.
