After one year of deep studies of chemical sciences at the University of Maine in France, Hamdi BEN YAHIA moved to the University of Bordeaux1 from where he received his Ph.D. in September 2006 in condensed matter physical chemistry. Thereafter, he worked as a postdoctoral appointee at the French National Research Center in France where he developed cathodes for fuel cells. In August 2008, he was awarded the Alexander Von Humboldt fellowship to work on superconductors at the University of Münster in Germany. In October 2010, he joined the National Institute of Advanced Industrial Science and Technology (AIST) in Osaka to work on positive electrode materials for lithium-ion batteries. His work was supported by the New Energy and Industrial Technology Development Organization (NEDO) in Japan. In November 2012, he was awarded the Japan Society for Promotion of Science (JSPS) research fellowship to work on positive electrode materials for sodium-ion batteries. During the last ten years, he discovered more than 80 new compounds for fuel cells, superconductors, and batteries. He authored two patent applications and published 48 peer-review papers.
