The rapid advancement of Na-ion battery (NIB) technology presents promising opportunities for energy storage, but challenges remain in understanding their performance, aging mechanisms, and safety. This postdoctoral position aims to design and validate an innovative reference electrode sensor for Na-ion batteries, enabling precise in situ and operando characterization.

The candidate will work on the development and implementation of a reference electrode (RE) adapted to Na-ion batteries, based on materials synthesized during the project. The validation of the sensor will involve the instrumentation of battery cells and cycling tests under various conditions, as well as the analysis of performance and aging mechanisms.

The candidate will perform data analysis and post-mortem examinations (SEM, EDX, ICP, etc.) to correlate sensor measurements with degradation phenomena.

The position is integrated within a multidisciplinary team and in collaboration with the LEDNA (IRAMIS) at CEA Saclay for material synthesis. The work will be conducted at the Electrochemical, Post-Mortem & Safety Analysis Laboratory (LAPS) at CEA Grenoble, a leader in energy storage research.
