We are looking for a post-doctoral fellow to join the collaborative project with TotalEnergies/SAFT, dedicated to investigate full Li-ion commercial batteries, and provide understanding of reaction & ageing mechanisms by means of operando neutron and synchrotron techniques at world-class Large Scale Facilities, coupled with electrochemical characterizations at CEA and SAFT and modelling at TotalEnergies.

You will benefit from the know-how gained at IRIG ) over the past years on operando battery characterization and evolve in a multidisciplinary environment (electrochemists, chemists and physicist), you will interact also with the industrial partner.

The role will be based in Grenoble.

The aims of the project:

  • Investigate cells after few cycles and longterm cycling under different charge regimes, including fast charging.
  • Quantify lithium distribution in active materials and electrolytes.
  • Investigate metallic lithium deposits formation mechanism.
  • Probe the structural and morphological evolutions during cycling.
We will employ diffraction/scattering tools as μXRD (see S. Tardif et al,

J. Chem Mat A 2021), SAXS/WAXS (see C. Berhaut et al,

ACS Nano 2019; Energy Storage Materials 2020), and advanced 3D techniques as synchrotron tomography and/or neutron imaging. The experiments will be performed on home-made battery cells and/or industrial cells provided by SAFT, on beamlines located at the European Synchrotron Radiation Facility (ESRF) and Institut Laue Langevin (ILL) in Grenoble.
As a Post-Doc, you will have the following responsibilities:

  • Design/test battery cells for X-ray and/or neutron experiments
  • Perform basic electrochemical characterizations
  • Plan/realize the operando experiments
  • Analyze/interpret the sets of data
