Dr. Hab.
Marion Chandesris is a senior researcher at CEA-Liten, where her research focuses on multiphysics and multiscale modeling of Li-ion batteries.
After graduating from engineering school École des Ponts et Chaussées, where she specialized in numerical analysis, she earned a PhD in fluid mechanics from Paris VI University, completing her PhD research at the CEA in Grenoble. She was granted accreditation to supervise research (Habilitation à Diriger des Recherches, or HDR) at Grenoble Alpes University.
She has been working at the CEA since 2003. Her early research focused on modeling and simulating heat transfer in nuclear reactors. In 2013, she joined CEA-Liten to work on new energy technologies. She headed CEA-Liten's battery and low-temperature fuel-cell multiscale modeling lab from 2020 to 2024.
Specifically, her research focuses on the modeling and simulation of multiphysics and multiscale systems. She has developed upscaling methods to factor in transfers in porous media and at interfaces and develops experiments for model validation strategy development. Finally, she has supervised several PhDs on these topics and is involved in multi-partner government-funded research programs (PEPR Batteries, Grenoble Battery HUB) and major industrial research projects.

Team
- Multiphysics modeling of electrochemical processes in batteries and the study of aging mechanisms;
- Development and validation of models at different scales: porous approach for electrode modeling, direct simulations based on electrode microstructure, and phase field methods for studying multi-phase active materials;
- Contributions to the development of electrochemical experiments and advanced experimental techniques (synchrotron techniques, NMR, etc.) to extend the scope of model validation.
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.
