Updated : 2021.11.03Organic batteries with solid-state electrolytes
The research project aims at building and test full organic solid-state battery composed of low-molecular
weight organic electrode materials with liquid-free electrolytes. First step will consist in formulating electrodes
(active material, conductive additive and liquid-free electrolyte) and investigate chemical stability using different characterization tools available in the laboratory. Secondly, electrochemical characterization of formulated electrodes will be realized in order to select best composite electrode for the cell building, finality of the project.

Stage M2 LRCS - Amiens
Updated : 2021.10.18Toward the development of thick electrodes for Li-ion batteries using Binder Jetting and Sintering
The improvement of the energy density of Li-ion batteries requires a significant increase of the surface and volume energy density. For this, one approach which can be considered is the increase of the thickness of the electrodes in order to increase the ratio of active material to dead material (i.e. inactive materials). The objective of the selected master student will be to develop a new solution to achieve efficient batteries with thick electrodes through an innovative process, i.e the Binder Jetting. The prepared electrodes will be characterized by various techniques to determine the microstructure, porosity and physical properties of the samples and will be tested in Li-ion batteries.

PhD Position LRCS - CSE-CdF - Start : October 2022
Updated : 2021.05.12Synthesis and study of Li-rich solid solution alloys as anode for solid state batteries
The topic of this PhD relies on the synthesis and study of Li-based solid-solution alloys as negative electrodes for Li batteries, with the goal of improving their electrochemical reversibility. We will focus on the control of the Li dendritic growth, which largely impede its use, either with organic liquid electrolyte or in “all solid state” inorganic configurations.ion, que ce soit en configuration « électrolyte liquide organique » ou en système « tout-solide inorganique ».

We wish to establish close relationships between stoichiometry, morphology, structure and electrochemical properties of fully characterized positive electrode powders for Li-Ion batteries. An exhaustive approach (precursors, thermal treatments under various pO2, substitution, …) will be used to tune the synthesis of high-performance Li(Ni,Mn)2O4-δ spinels. Phase equilibria during synthesis will be explored in situ using T-controlled XRay or Neutron diffraction under various atmospheres.

Updated : 2020.01.31Maîtrise des interfaces via des polymères conducteurs pour le stockage de l’énergie
L’objectif de ce projet est d’augmenter les performances des électrodes constitutives des batteries en substituant la masse « non active » des électrodes (liant polymère + additif conducteur carboné) par des polymères conducteurs tout en améliorant significativement leur adhérence sur le collecteur de courant. Ainsi, une approche biomimétique basée sur le greffage d’un polymère adhésif et conducteur est proposée pour maitriser les interfaces et construire de nouvelles architectures d’électrodes organisées et entièrement conjuguées avec le collecteur de courant.
