Descriptif des activités de rechercheOPERANDO investigation of Battery Materials: The main goal of the project is to do crystallography work on cathode materials for advanced batteries, within the LRCS Laboratory. The work will be conducted under the scientific supervision and responsibility of Assoc. Prof. Jean-Noël CHOTARD and Prof. Christian MASQUELIER. The research project will focus on i) the development of new operando electrochemical cells to be operated in transmission geometry within a brand new X-ray diffractometer and ii) the operando study of electrochemical mechanisms within high rate positive electrode materials for Lithium or Sodium ion batteries. This work forms part of intense collaborative research work within the French RS2E Network (in particular with the group of Laurence CROGUENNEC in ICMCB Bordeaux) and with large scale facilities such as ALBA Synchrotron (Dr. François FAUTH), SOLEIL Synchrotron (Dr. Antonella IADECOLA) and the ILL Grenoble (Dr. Emmanuelle SUARD).
