Materials/Synthesis Approaches for Developing Sustainable Li-ion Batteries for Energy Storage
Speaker: Professor Jean-Marie Tarascon, Université de Picardie Jules Verne
Series: Other Events
Location: Bowen Hall
Date/Time: Wednesday, November 23, 2011, 12:00 p.m. - 1:00 p.m.
Although today's Li-ion technology has conquered the portable electronic markets, and is still improving, it falls short of meeting the demands dictated by both electric transportation and grid applications. There is room for optimism as long as we pursue paradigm shifts while keeping in mind the concept of materials sustainability. Some of these concepts relying i) on new ways to prepare known or new inorganic phosphates, fluorophosphates or fluorosulfate electrode materials via eco-efficient processes enlisting ionothermal or bio-inspired approaches, ii) on proposing organic electrodes, and iii) exploring new insertion chemistries, will be discussed.
Bio: Jean-Marie Tarascon is a specialist in chemistry/electrochemistry of solids. He is presently professor at the Université de Picardie Jules Verne in Amiens. Yet, most of his career was spent in the United States, at Cornell University first (1980), then at Bell Laboratory and Bellcore until 1994. His research first focused on a few of the electronic properties of the Chevrel phases as well as their ability to insert/de-insert. At the end of the 1980’s he became Director of the Energy Storage Group, Bellcore, and contributed to the results on high temperature cuprates superconductors, the role of stoichiometry in oxygen, cationic substitutions, magnetism or modulation of structures. However, he went back to the electrochemistry of solids and became a world famous specialist: he is the one who set up the presently commercialized Li-ion battery based on a new all plastic technology. His recent works having demonstrated: 1) the new mechanism of the Li reactivity vs. oxides, sulfides, nitrides and fluorides; 2) new eco-efficient methods of synthesizing electrode materials; 3) the discovery of a new family of fluorosulfides operating at high potential; and finally, 4) the feasibility of using electrodes based on electro-active organic molecules issued from biomass, illustrate his constant desire to wander off the well-established scientific concepts. He has been rewarded time and time again, and is the holder of more than 70 patents and has co-signed more than 520 publications.
