Li-ion technology. Back to France in 1995, he created the European network of excellence ALISTORE-ERI of which he was head until 2010 when he took over the direction of the new LABEX “STOREEX”. In 2011 he became in charge of the recently created French network on electrochemical energy storage (RS2E). The general scheme of his research focuses on the synthesis, characterization, and determination of structure/property relationships of electronic, superconductor and rechargeable battery materials for solid state electronic devices. Presently his activities are more devoted to Li-ion, Na-ion batteries and other chemistries with emphasis on developing new eco-efficient synthesis processes and developing novel reactivity concepts. He is the author of more than 600 scientific papers, and detains about 80 patents. During his life, he received many honours, with the latest being the ENI and Pierre Sue awards in 2011, the ABAA in 2013 prior to come foreign member of the royal society in 2014 and received the 2015 Centenary price Centenary Prize in the Royal Society of Chemistry’s.
Yoshitaka Tateyama National Institute for Materials Science, Japan Ab-initio MD Simulations of Redox Reactions of Liquid Electrolytes and SEI Formation Atomistic understanding of solid electrolyte interphase (SEI) formed at the interface between electrode and liquid electrolyte is still an issue of great importance. However, difficulties in experimental insitu observations of the buried interfaces and simulations considering the liquid dynamics (fluctuation) and reaction have inhibited the progress of elucidation. We have addressed such issues by means of accurate large-scale ab-initio molecular dynamics (MD) samplings and free energy calculations on a huge supercomputer. In this talk, we will introduce our recent findings of (i) a novel role of vinylene carbonate additive on reductive decomposition of ethylene carbonate electrolyte, (ii) a novel formation mechanism of organic SEI components with near-shore aggregation, and (iii) their extensions to different electrolytes. These ab-initio studies on the atomic scale will provide a new microscopic perspective of SEI. Yoshitaka Tateyama is the group leader of Nano-System Computational Science Group in International Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS). He is also a principal investigator in the Elements Strategy Initiative for Catalysts & Batteries, Kyoto University. He received PhD degrees in physics from the University of Tokyo in 1998, and started his research carrier as a staff member in NIMS. In 2003-2004, he worked in the University of Cambridge as a visiting researcher. He was appointed as a MANA independent scientist in 2007, and promoted to a group leader in 2011. His research focuses on (1) development of novel DFT calculation techniques for redox, interfacial and electrochemical reactions, and (2) their applications to electrochemical issues. Recently, he has intensively studied electrolyte-electrode interfaces in lithium ion batteries by means of DFT-based statistical simulations on the K computer, a flagship supercomputer in Japan, and succeeded in unveiling several atomistic mechanisms of redox reactions of electrolyte and SEI formation at the interfaces. For these contributions, he won the 7th German Innovation Award in 2015.

Michael Thackeray Argonne National Laboratory, USA Strategies and Advances in the Structural Design of Lithium Metal Oxide Electrodes Structurally-integrated, high capacity xLi2MnO3• (1-x)LiMO2 (M=Mn, Ni, Co) electrodes that contain a spinel component are of interest because they offer the possibility of mitigating the voltage fade that occurs when the electrodes are continuously cycled and charged to a high potential, typically 4.6 V or higher. Advances in designing cathode materials by tailoring the structure and composition of the electrode, and by finding a compromise between capacity, cycling stability and voltage fade, will be discussed in the presentation. Michael Thackeray is a Distinguished Fellow and senior scientist in the Electrochemical Energy Storage Department of the Chemical Sciences and Engineering Division at Argonne National Laboratory. He received his PhD from Cape Town University, South Africa in 1977 and undertook post-doctoral research at Oxford University, UK in 1981/82. He returned to South Africa to become manager of the Battery Unit at the Council of Scientific and Industrial Research (CSIR), South Africa before moving to Argonne in 1994. Between 2009 and 2014, he was the Director of one of the U.S. Department of Energy’s Energy Frontier Research Centers (EFRCs), the Center for Electrical Energy Storage with Argonne as the lead institution and Northwestern University and the University of Illinois at UrbanaChampaign as partners. His principal research interests include the design of lithium battery electrode materials and their structureelectrochemical property relationships. Dr. Thackeray has presented the results of his research widely at invited lectures across the globe. He has been the recipient of several notable South African and international awards, his most recent honors including the American Chemical Society E. V. Murphree Award in Industrial and Engineering Chemistry (2016), a DSc honoris causa from the University of Cape Town (2014), a Fellowship of the Electrochemical Society (2014), and the International Battery Association Yeager Award for life-long achievements in lithium battery materials science and technology (2011).
Yoshiharu Utchimoto Kyoto University, Japan Operando Analyses of Reactions using Synchrotron Radiation and the Design of High Rate Capability Cathode To improve the performance of lithium ion batteries, it is essential to understand reaction hierarchies over wide temporal and spatial ranges. To this end, operando measurement techniques have been developed that enable analysis of the electrode/electrolyte interface of the reaction site, phase transitions of active materials, and macro reactions within real electrodes over various spatial and temporal scales. These analytic techniques pioneer a new way of performing kinetic analysis by introducing axes of space and time into reaction analyses, and are applicable to various types of electrochemical devices. Yoshiharu Utchimoto is a professor in the Department of Interdisciplinary Environment, Graduate School of Human and Environmental Studies, Kyoto University, Kyoto, Japan, a position he has since 2007. He received his Doctor of Engineering degree in 1991 from Kyoto University. In 1993, he was a post-doctoral fellow at University of Pennsylvania, USA. Prof. Uchimoto’s recent work is focused on electrochemical energy storage and conversion devices, including lithium ion batteries, post lithium-ion batteries, proton exchange membrane fuel cells, and solid oxide fuel cells. He aim at the development of state-of-the-art techniques of analysis of battery operando by using large-scale equipment, such as synchrotron radiation beam facilities, to be utilized in the enhancement of the performance of the existing lithium-ion batteries as well as the development of post lithium-ion 18th International Meeting on Lithium Batteries w Chicago, Illinois w June 19–24, 2016
