Description of the thesis topic
This thesis topic is part of the European BIG MAP project (https://www.big-map.eu/) whose ambitious objective is to accelerate the discovery of new materials for electrochemical energy storage ( batteries) through the development of high-performance simulation tools (Artificial Intelligence, Machine Learning).
In battery electrodes, the electrode / electrolyte interfaces play a major role since they partly control the electrochemical reactivity. Mastering these interfaces is therefore one of the major challenges for improving the battery performance and in particular for understanding the aging mechanisms, and they therefore need to be perfectly characterized using complex / coupled techniques. These characterizations are generally separated from the models, contrary to this project whose goal is to enrich them via free and standardized access to experimental data. This thesis will deal with the characterization of interfaces of negative electrode materials by electrochemical techniques (EQCM, Complex Impedance Spectroscopy, Cyclic Voltammetry, Galvanostatic or Potentiostatic Cycling) and other characterization techniques depending on the nature of the electrolyte and current density.
The thesis will take place at equal time between the LRCS of Amiens (Laboratory of Reactivity and Chemistry of Solids UMR CNRS / UPJV 7314) and the CIRIMAT of Toulouse (Interuniversity Center for Research and Engineering of Materials, UMR CNRS 5085 - Paul University Sabatier Toulouse III).
The LRCS (UMR CNRS / UPJV 7314) is a research laboratory on energy storage and conversion. 35 experienced scientists (teacher-researchers and CNRS researchers) and 45 young researchers are working on batteries of today and tomorrow, on photovoltaics and hydrogen storage.
CIRIMAT (UMR CNRS 5085 - Université Paul Sabatier Toulouse III) specializes in materials. Patrice Simon's team has significant experience in super-capacitors, electrochemical characterizations.
