Description du sujet de thèse
Positive electrode materials for Li- and Na-ion batteries often contain combinations of elements
considered critical or toxic (Mn, Co, Ni) to enhance their performance and stability. The development of
new sustainable compositions for positive electrodes requires an eco-design approach that reduces
reliance on critical raw materials and facilitates the recycling of spent materials.
This thesis aims to design, synthesize, and characterize the structure and properEes of new
sustainable composiEons for posiEve electrode materials in Li- and Na-ion baFeries using the mixed-anion
strategy. Mixed-anion materials contain two or more anions within the same framework (e.g., O2−, F−, Cl−,
etc.). Although several materials are already known, such as Li2FeOS and LiMnO2F, mixed-anion
compounds remain less common than their single-anion counterparts. This PhD thesis will consist in
exploring novel composiEons through a wide range of synthesis techniques, determine the structure of
the new materials, invesEgate their electrochemical properEes and study the correlaEon between
composiEon, structure and properEes using theory
Contexte de travail
Created in 1995, the Bordeaux Institute of Condensed Matter Chemistry (ICMCB) focuses its research on Solid State Chemistry, Materials Science and Chemistry and Process: designing, preparing, shaping and characterizing materials in order to discover, control and optimize specific functions. The ICMCB carries out fundamental research on model materials and/or materials with potential applications.
The ICMCB is a UMR with an average of 280 agents (permanent and non-permanent), with 3 tutelles, hosted by the CNRS and in total ZRR. The position is located in a sector covered by the Protection of Scientific and Technical Potential (PSTP), and therefore requires, in accordance with the regulations, that the arrival of the agent be authorized by the competent authority of MESR.
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.
Contraintes et risques
No risk other than the ones typically encountered during the practice of inorganic solid-state chemistry
