Date: 5th December 2018 (Wednesday) | Time: 10:30 a.m. – 12:00 noon (Registration at 10:00 a.m.) | Venue: Lim Por Yen Lecture Theatre 2 (N002), G/F, Block N, PolyU (Campus Map)

Abstract


The development of improved rechargeable batteries represents a major technological challenge for this new century, as batteries constitute the limiting components in the shift from gasoline powered to electric vehicles, while also enabling the use of more renewable energy on the grid. To minimize the ecological implications associated with their wider use, we must integrate sustainability of battery components into our research endeavors. The challenges to developing batteries with minimal ecological footprints are enormous. They call for new materials and new concepts, as well as new chemical compositions. The presentation will address these different aspects. Firstly, regarding new concepts, we will show how the discovery of a reversible lithium--driven anionic redox process among lithium-rich layered oxides represents a transformational approach for creating materials with exacerbated capacities. Secondly, concerning sustainability, our new findings with the sodium ion chemistry which uses novel materials design together with the assembly of 18,650 prototypes will be presented. Lastly, the future aspects of battery research will be discussed.

About the Speaker

Professor Jean-Marie Tarascon

Professor at Collège de France, Paris
Director of Research Network on Electrochemical Energy Storage


Jean-Marie Tarascon is a specialist of Solid-State Chemistry. He started his carrier in the U.S., first at Cornell University (1980), then at Bell Labs and Bellcore until 1994. He then became Professor at the Université de Picardie Jules Verne and Director of the Laboratoire de Réactivité et Chimie des Solides (LRCS UMR CNRS 7314) in Amiens. He founded in 2011 the French Research Network on Electrochemical Energy Storage (RS2E, http://www.energie-rs2e.com), a CNRS research federation grouping together industrial and academic actors of the batteries and supercapacitors fields.

His first researches were focusing on electronic properties of Chevrel phases as well as their ability to insert alkali cations. At the end of the 1980’s, Jean-Marie Tarascon headed the chemistry group at Bellcore and participated to the results obtained on high Tc cuprates supraconductors and the role of oxygen non-stoichiometry, cationic substitutions, magnetism or structure modulation. He thereafter came back to electrochemistry and became a worldwide recognized specialist on energy storage. Jean-Marie Tarascon’s credits as a battery researcher include the development of a plastic and flexible Li-ion battery. Since he moved back to France, he is working on advanced technologies for tomorrow’s batteries, enlisting the development of new “chimie douce” synthesis routes for battery materials, Li-rich layered materials, metal-air batteries and electrocatalytic reactions as well as redox flox systems and other technologies going beyond Li-ion batteries (for instance Na-ion batteries). He took up the Chair of Solid State Chemistry and Energy at Collège de France in 2014 where he is now Professor.
