AbstractContext and challenges :
The current environmental and economic context leads us to look for new clean, reliable and energy-efficient industrial devices. Depending on the application and the technical constraints (weight, size, performance, durability...) various systems are used but there are still technological obstacles to be overcome. Among the electrochemical energy storage systems, the choice of the device depends on the power or energy densities required, the reliability of the system required. The materials making up the electrodes (nature, texture, structure, surface chemistry) have a major role to play.

In this context, Mines ParisTech proposes a Ph.D position consisting in developing, characterizing and evaluating new electrode materials for energy storage systems based on carbon and metal oxide. This work will be based on the expertise of the laboratory developed over many years both on these materials and on their applications as electrode material (storage or conversion). The work will be carried out at the PERSEE center located in Sophia Antipolis (06) within the Matpro group (https://www.persee.minesparis.psl.eu/Accueil/Presentation/) and will be carried out as part of a collaborative project (ANR) involving other academic laboratories.
The student will be registered for a PhD PSL / MINES ParisTech in the doctoral school Engineering Systems, Materials, Mechanics, Energy - ISMME from October 1, 2021.

General scientific objectives :
1. Elaboration and fine physicochemical characterization (ATG, SEM, BET, XRD, XPS...) of new C/MOx electrode composite materials responding to the technical specificities of the application.
2. Evaluation of the electrochemical performances of these materials used in the test cell.

Approach - Methods: The actions will aim at:
1. to realize hybrid electrode nanostructured materials (carbon/metal oxide) by sol-gel, hydrothermal methods,...
2. to optimize the elaboration processes
3. to adapt the composition, structure, texture and surface state of the C/MOx to improve performance and behavior during cycling
4. to evaluate and validate the selected solutions in terms of performance and durability.

Expected results
1. to master of the steps of electrode synthesis
2. to understand the influence of the synthesis parameters on the physico-chemical and electrochemical characteristics and durability of the final material.
ProfileProven ability in experimental research, well organized and self-motivated, good communications skills both orally and written in English.

Good skills in chemistry, material sciences and electrochemistry.
