High energy density batteries made from inexpensive sustainable resources would be attractive for a number of mobile and stationary applications. Lithium-ion batteries have been the best choice as commercial rechargeable batteries for portable devices and transportation applications since 1991. Nevertheless, concerns are raised about the fact that lithium is a limited
resource with an inhomogeneous geographical distribution of its natural feedstock. This scenario is worsened by an increasing consumption of lithium per year around the globe due to its use in different fields, thereby resulting into a steep increase of its costs.
Rechargeable Na-ion batteries can be considered as a serious alternative due to the natural abundance and the low cost of sodium, the safety of the systems. Indeed, a great number of compounds have been studied as positive electrode materials for sodium ion batteries, e.g. Nascion-type phosphates, lamellar oxides, ….
The electrochemical behaviour of such electrode materials during cycling completely differs from that of homologous lithiated phases. So, many research works investigated the evolution of the electrodes features with the sodiation/desodiation processes. Here, we will present two examples of electrode materials for which the mechanism of the sodium insertion/extraction was explored and explained.
Biography
Ismael SAADOUNE, Full Professor in the University Cadi Ayyad (UCA) since 2000, was born in Casablanca in 1965 and graduated from the University of Bordeaux, France (French PhD) and the University Cadi Ayyad of Marrakech, Morocco (Moroccan PhD). These Two PhDs were focused on Material Science with the specific research topic ‘Lithium-ion Batteries as efficient energy storage system’.
In 2002, He created the Laboratory of Materials and Environmental Chemistry in UCA. More than 100 graduate and 40 Master students were hosted in his Lab. 14 PhD Students have been under his supervision, all of them are now involved in the Industry or in research laboratories. He is the principal investigator of 8 national and 12 international research projects. He is involved in two European Master ERASMUS MUNDUS: ‘Materials for Energy Storage and Conversion’ and ‘Functionalized Advanced Materials and Engineering’.
Professor Ismael SAADOUNE was recently received an award from Tokyo University of Science, Japan as a result of his intensive activity on lithium ion batteries.
He has authored/co-authored over 150 peer-reviewed, conference papers, and project reports. He is currently a member of editorial boards for three journals and reviewer of more than 100 research papers. His publications have received more than 1400 citations and his Hirsch index is h = 17.
Pr I. Saadoune has been visiting professor in many universities and research institutes within international scientific collaborations (Germany, Spain, Japan, France, Sweden, South Korea, USA).
