The selected candidate will be recruited in the frame of the project named RECYLION (development of RECYcling process for Lithium-ION batteries with low-environmental footprint) in case of funding is obtained.
The aim of the project is to prove the feasibility of a sustainable process of separation of the valuable elements included in Li-ion batteries (lithium, cobalt, nickel, manganese, graphite…) by avoiding, as much as possible, the manual dismantling of the batteries. The process developed in the project has the advantage of being suitable for all kinds of Li-ion batteries, especially the different materials that can be found at the cathode (LiCoO2, LiMn2O4, LiNiMnCoO2, LiNiCoAlO2, LiFePO4…). The different parts of the battery will be processed one by one, to gradually move towards a process involving the battery as a whole if this is possible.
The process uses a solvent having a very low environmental impact, and it is carried out at relatively low temperature. The declaration of invention of this new process has just been filed. At the end of this process, the chemical elements constituting the cathode materials are in the form of oxides, carbonates or hydroxides, depending on the element, the most important being that the different elements are separated from each other in several compounds.
The recycling process, carried out in the GPM laboratory, will be applied to commercial battery materials, new and used, but also to the compounds constituting these batteries, taken alone. These compounds will be synthesized in the CRISMAT laboratory, which has a recognized experience in the field of synthesis of batteries compounds. The application of the method to the battery compounds, taken alone, will isolate the effect in order to optimize the conditions during the treatment of the entire battery.
The candidate will work in close cooperation with the CRISMAT partners.
- Implementation and possible modifications of the recycling process developed in the GPM.
- Structural characterization of the products obtained at the end of the process.
- Analysis of experimental data and interpretation of results in order to improve the yield / efficiency of the process.
The candidate must have a Ph.D in Physics, Material Science, Chemistry, or a closely allied field. A strong experience in synthesis and materials characterization is required. He/she should be autonomous to perform chemical treatments, for usual characterization techniques (X-Ray diffraction, Scanning Electron Microscopy….), and for the interpretation and synthesis of the experimental data. Skills in characterization of magnetic compounds are desirable. The successful candidate will be highly motivated, with demonstrated abilities to work in a collaborative environment.
The research laboratory "Group of Physics of Materials (GPM)" is organized in five Scientific Departments : Scientific instrumentation, Metallurgy, Nanosciences and nanotechnologies, Disordered systems and polymers, Nanoparticles: characterization and environment.
The laboratory has 160 staff (60 professors, assistant professors and full time scientists; 30 application engineers, technicians and administrators; about 70 PhD students).
The laboratory is located in the premises of the University of Rouen Normandie and the INSA of Rouen Normandie, on the science campus of the “technopole du Madrillet” (situated in the south of Rouen city).
The candidate will be affected to the Nanosciences and nanotechnologies department in the ERMMA team (Magnetic Materials and Applications Research Team)
This work will be performed in collaboration with the CRISMAT laboratory (ENSI Caen, France, NMF2 team).
Constraints and risks
The candidate will work in a chemistry laboratory. A radiation safety training concerning chemical risks will be delivered at the beginning of the position.
subject to obtaining the RIN Tremplin funding (RECYLION project)
