Claude Delmas

Claude Delmas is Emeritus CNRS Research Director at the Bordeaux Institute of Condensed-Matter Chemistry (ICMCB), located on the campus of the University of Bordeaux in France. He received his DSc Degree in solid-state chemistry at the University of Bordeaux in 1976. In 1985, he created the Solid-State Ionics Group at ICMCB and, in 2004, he became director of the institute.

Delmas is a Solid State Chemist working in the field of positive electrode materials for secondary batteries. His expertise concerns layered oxides and phosphates able to intercalate reversibly hydrogen, lithium and sodium. In the 80’s – 90’s, he made pioneering intercalation works in sodium layered oxides, in lithium cobalt substituted nickel oxides and in Nasicons. He proposed a general classification of the layer oxides, which is now used by all the scientific community working in this field.

Delmas’ most successful studies have involved stabilization of metastable phases with unusual oxidation states, determination of structural derivations and characterization of extended defects. Most of his works were made in connection with industrial worldwide companies. He has authored or co-authored more than 320 scientific publications and holds 16 patents.
