The lithium-ion capacitor (LIC), which internally hybridizes an EDL positive electrode and a LIB negative one made from graphite, delivers much higher power than LIBs and higher energy than traditional EDL capacitors. Since lithium must be first intercalated into the graphite electrode, this presentation introduces a novel strategy where a sacrificial lithiated material is incorporated together with activated carbon in the positive electrode. While lithium is transferred to graphite, the remaining part of this material either evolves as neutral gas or is dissolved in the electrolyte.

講演者の経歴 (Francois Beguin)

François Béguin was Professor and leader of the Energy&Environment Group in Orléans University (France) till 2011, and he is now Professor in Poznan University of Technology (Poland), where he has been awarded the WELCOME stipend from the Foundation for Polish Science.
His research activities are devoted to chemical and electrochemical applications of carbon materials, with a special attention to the development of nano-carbons with controlled porosity and surface functionality for applications to energy conversion/storage and environment protection. The main topics investigated in his research group are lithium batteries, supercapacitors, electrochemical hydrogen storage, reversible electrosorption of pollutants. He owns several patents related with the synthesis of nano-structured carbon materials (nanotubes, carbons from biomass, ...) and their use for electrochemical systems. He published over 260 publications in high rank international journals and his works are cited in 12000 papers. His Hirsch index is H = 52.
He is also involved in several books dealing with carbon materials and energy storage. Recently, he edited the book "Supercapacitors - Materials, Systems and Applications. He is a member of the International Advisory Board of the Carbon Conferences and he launched the international conferences on Carbon for Energy Storage and Environment Protection (CESEP). He is member of the editorial board of the journal Carbon.
In the French Agency for Research (ANR), he was Director of national programs on Energy Storage and Hydrogen and Fuel Cells till 2012.
