Lithium-ion batteries and beyond

SUNUM G111
Over the past 25 years, lithium ion batteries (LIBs) played a crucial role in the development of energy storage technologies. Today LIBs are used in 90% of rechargeable portable electronic devices. Although great improvements have been accomplished, and while active research for further developments continues, current lithium-ion technologies provide a limited gravimetric energy density which cannot compete with neither fulfilling the goal of replacing combustion engines nor meeting large mass energy storage back-up dictated by solar farms or wind turbines plants. For instance, electrical vehicles (EVs) powered by lithium-ion batteries result in an inadequate driving range (160-200 km). Therefore, more drastic approaches are necessary to go beyond this limit and to accomplish “The Holy Grail” of a 500 km driving range at low cost, without the need for hybridization with conventional internal combustion engines.
The seminar will start from the basic history of the batteries to lithium-ion batteries with the most important developments in the field. Then, the implementation of the very challenging lithium-sulphur technology will be discussed with very recent findings in the area.
About the speaker
Rezan Demir-Cakan is an Assistant Professor at the Chemical Engineering Department of Gebze Technical University in Turkey. Dr. Demir-Cakan graduated from Yildiz Technical University, Chemical Engineering Department. She completed her MSc. from the same department guided by Professor Ulker Beker. She received her Ph.D. degree in Materials Chemistry at the Max Planck Institute of Colloids and Interfaces, in Germany (2009) in the group of Professor Markus Antonietti working on the synthesis, characterization and applications of hydrothermal carbon materials. Then she worked at the “Laboratoire de Réactivité et Chimie des Solides” in Amiens (2009-2012) in the group of Jean-Marie-Tarascon focusing on the lithium batteries, more specifically on lithium-sulfur batteries. Her current research focuses on the synthesis of nanostructured energy materials and their application in the field of Li/Na batteries and hydrogen storage. She has received the “The Science Academy Young Scientist Award” (2015), “Young Investigator Award” (2012) and the “Japan Carbon Award for Student” (2008). She has co-authors of over 30 papers in international peer reviewed journals (total citation: ~2000, h-index: 15), one patent and three book chapters. She is currently editing a book on Li-S batteries from Imperial College Press.
