  2. All-solid-state batteries
  3. Nanostructured materials for post-lithium batteries

Biography

Saïd Yagoubi is a lecturer in materials science at the University of Paris-Saclay since 2008. He obtained his doctorate in solid-state chemistry in December 2004 at the University of Lille, France.

After two years as an ATER (temporary teaching and research associate) in Lille, he did his postdoctoral research from 2006 to 2008 at the Institute of Transuranium Elements (ITU), JRC-European Commission in Karlsruhe (Germany).

During his postdoctoral research program, he worked on the behavior of 5f electrons (localized or roaming) for metals and intermetallic compounds by synchrotron X-ray diffraction under high pressure (up to 300 GPa).

Dr. Saïd is now attached to the LEEL laboratory at the CEA Paris-Saclay. His current research focuses on the relationship between synthesis, structure, and transport properties in advanced all-solid-state lithium and sodium battery materials.
