Description du sujet de thèse

A PhD thesis entitled 'Development by Additive Manufacturing of Solid State Batteries (DAGOBA)' will begin next September on the topic of FFF 3D printing of batteries developed as part of the Limasse project (all-solid-state lithium metal batteries). This 3D printing project is an extension of the research carried out as part of the ANR IODA project (3D printing of lithium ion batteries with liquid electrolyte) and the ESA GROGU project (battery with polymer electrolyte). These two projects benefit from the patent we have filed and which uses the Co continuity of immiscible polymers). Within the framework of the PEPR LIMASSE, we will need to adapt the formulations in order to be able to cycle materials with higher potential such as Nickel Rich NMC 811. For the electrolyte, as part of WP3 of the LIMASSE project, the best argyrodite-based formulations developed by the Polymer Materials Engineering (IMP) laboratory in St Etienne will be shaped into filaments before being printed. for the negative electrode, formulations suitable for the introduction of low-potential active materials (lithiophilic substrates) will also have to be developed.

Contexte de travail

This PhD thesis will be carried out as part of the PEPR Limasse project (all-solid-state lithium metal batteries).
The Laboratoire de Réactivité et de Chimie des Solides (LRCS); a dynamic joint research unit between the CNRS and the University of Picardie Jules Verne, is located in Amiens. It hosts more than 130 people of 25 different nationalities, who work mainly on technologies for the electrochemical storage of energy (batteries) and the conversion of solar energy (photovoltaics).

Le poste se situe dans un secteur relevant de la protection du potentiel scientifique et technique (PPST), et nécessite donc, conformément à la réglementation, que votre arrivée soit autorisée par l'autorité compétente du MESR.
