Postdoctoral / Li-ion Batteries H/F

Description du poste

The postdoctoral researcher will conduct research work dedicated to advanced Li-ion battery systems. Their work will focus in particular on multiphysics coupling, parameter identification and experimental validation under various operating environments.

Priority Research Axes

• Electro-thermal modelling: development of coupled models, from enhanced equivalent-circuit models to more physics-based approaches such as simplified SPM/P2D models or finite-element models, accounting for irreversible losses, entropic heat, SoC-temperature-C-rate dependent parameters and, where relevant, ageing indicators.
• Experimental characterization: definition and implementation of protocols on Li-ion cells, especially LFP 18650/26650 cells or other available formats, using a battery cycler, climatic chamber, thermocouples/IR measurements, and OCV, pulse, charge/discharge tests at different C-rates and repeated cycling conditions.
• Parameter identification and validation: inverse identification of electrical and thermal parameters, comparison between model predictions and measurements for voltage and surface temperature, sensitivity/uncertainty analysis, and development of a reduced-order model suitable for thermal sizing or battery management applications.
• Application-oriented extension: preparation of the transition from cell to module scale, definition of thermal and energy performance indicators for lifetime and state-of-health (SoH) assessment, and possible contribution to an experimental digital twin for batteries under controlled operating conditions.

Research

• Conduct an original research program on Li-ion battery systems coupled with thermal and electrochemical aspects.
• Produce scientific publications in peer-reviewed journals (at least one high-impact international publication).
• Participate in national and international conferences to disseminate results.
• Contribute to the laboratory’s collaborative research projects and support future projects or PhD theses.
• Develop analysis and optimization models (validated and documented multiphysics numerical models).

Valorisation and Laboratory Activities

• Participate in the development of research projects (national and international) and contribute to interactions with industrial partners.
• Participate in the supervision of students (masters, doctoral candidates) on battery modelling and characterization aspects.
• Valorise research results (reports, workshops, technology transfers), particularly through the creation of a voltage-current-temperature-SoC database and the formalization of a design procedure to guide experimental protocols for thermoelectric characterization.
• Contribute to pedagogical activities related to energy/storage themes if required.
