Description du sujet de thèse

As part of the energy transition, the development and design of new materials for energy storage and conversion are major challenges. A detailed understanding of surfaces and interfaces is essential to improve the performance of these systems and lead to technology transfer.
The implementation of a set of near-field microscopy characterization techniques to gain access to the surface properties of electrodes for energy storage, in particular as applied to Li-ion batteries, should enable these improvements. The techniques used in this project will include atomic force microscopy (AFM) for topology characterization, Quantitative Nanomechanical Microscopy (QNM), Scanning Electrochemical Microscopy (SECM) and electrical measurements (TUNA).

Objectives :
- Implement electrochemical material characterization techniques
- Implement a set of near-field microscopy characterization techniques to gain access to the surface properties of electrodes for energy storage, in particular as applied to Li-ion batteries (Techniques used: AFM, QNM, SECM, TUNA).
- Gain detailed knowledge of the surfaces and interfaces of characterized electrodes.

Contexte de travail

The Research and Innovation in Electrochemistry for Energy team at the Institut de Chimie Moléculaire et des Matériaux d'Orsay (www.icmmo.u-psud.fr/fr/equipes/eriee/ ) aims to work on a number of themes of major societal interest: the hydrogen chain, CO2 recovery, lithium batteries and photo-electrochemistry.
Its activities range from the synthesis and characterization of materials (solids, molecular complexes) and their electrochemical properties, to the development of prototypes (electrochemical engineering) and industrial valorization.
- The project will be funded by a CNRS contract.
- The candidate will benefit from access to ICMMO's experimental resources.

The position is located in a sector under the protection of scientific and technical (PPST), and therefore requieres, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
