Stage Bac+5 Internship In Materials Chemistry Engineering For a Master'S Degree H/F CEA

Internship Objectives:
The main objective of this internship is to contribute to the development of innovative hybrid solid polymer electrolytes for high-performance lithium-ion batteries. A critical aspect of the project involves characterizing the electrochemical properties of these new hybrid electrolytes. This includes measuring their ionic conductivity, stability, and performance across a range of temperatures. These tests will be conducted using specific coin cell configurations and will include voltametric and galvanostatic tests on metallic and composite electrodes. Impedance and transference number measurements will also be carried out. The intern will work closely with electrochemistry experts from Liten-DEHT-STB in preparing and testing these assemblies.

Research Approach:
The project will be carried out in close collaboration between two research teams with complementary expertise:
Liten : The intern will work under the guidance of Liten-DEHT-STB researchers for the electrochemical characterization of the hybrid electrolytes. The intern will gain hands-on experience in coin-cell assembling, battery testing, understanding how material properties translate into device performance.
SyMMES: A part of the internship will involve collaboration with SyMMES researchers, that develop hybrid electrolytes. The lab has strong experience in nanostructured materials and advanced techniques for membrane preparation and characterization.
