The project entitled “In situ analysis of structural, gravimetrical and mechanical changes of electroactive materials during ion flux” aims to investigate the correlation of i) structural parameters, ii) mechanical stresses and iii) ion transfer/transport dynamics of electroactive materials using coupled techniques: advanced electrochemistry methods derived from electrochemical impedance spectroscopy (EIS), electroacoustic analysis, quartz crystal microbalance (QCM), and coupling EQCM based methods with in situ synchrotron XRD. This research project has implications in the optimization of the modified electrode/electrolyte interface intervening in energy storage device development.
Task I: 2D layered pseudocapacitive electrode synthesis / Classical structural and morphological characterizations / Performance Evaluation.
Task II: In situ Techniques for Advanced Analysis (transfer/transport properties of species at interface/through the electrode, electromechanical and structural analysis during cycling): EQCM, electrogravimetric and electroacoustic impedance, “In situ synchrotron XRD coupled with EQCM”
Task III: Analysis/Modelling of the electrogravimetric and synchrotron XRD results
Task IV: Data presentation, participation to publication preparation.
-Ph.D. in material science or analytical chemistry with strong skills in electrochemistry, hands-on experience on spectroscopic methods (i.e. impedance), XRD and QCM based methods.
-Experience on energy storage materials synthesis/characterization or on synchrotron experiments is appreciated.
-Ability to work as an independent researcher with a high level of scientific judgement and initiative.
-Excellent communication and organization skills.
-Oral and written English proficiency, French skills are appreciated.
The LISE laboratory is a mix research unit associating the CNRS (National Center of Scientific Research) and Sorbonne University (Jussieu campus, Paris), employing 70 persons. The research areas of the "Interfaces and Electrochemical Systems" laboratory are corrosion and its inhibition, surface treatments, energy storage and conversion, as well as the investigation of the behaviour of interfaces in natural environments. The main activities of the laboratory are:
- the development of methods based on electrochemical kinetics and the development of sophisticated instrumentation for their application to electrode-electrolyte interfaces,
- the development, modification, structural and/or chemical characterization of electrochemical interfaces and the modelling of their electrochemical behaviour.
The research of LISE is structured around 3 themes: (i) Theme 1. Microsystems and multi-scale electrochemistry for material characterization , (ii) Theme 2. Materials and interfaces: functionalities and electrochemistry and (iii) Theme 3. From electrochemical reactivity to molecular mechanisms. This project falls into the topics covered in the “Theme 2: Materials and interfaces: functionalities and electrochemistry” and in particular of the transversal axes entitled “Axis 3: Electrochemical storage and energy conversion” and “Axis 2: Instrumental developments and technique coupling” of our laboratory.
