ABSTRACT:
Mass adoption of electric vehicles (EVs) for decarbonization is presently hindered by battery safety, high cost, and low utilization of critical raw materials. Today’s lithium ion batteries (LiBs), originated from application to man-portable electronics, are not designed to exhibit safety, lifetime and operational robustness required of machine-like applications like EVs. For example, thermal runaway in LiBs with highly volatile and flammable electrolytes caused General Motors’ vehicle recall of $1.8B loss in 2021. Same batteries also experience severe degradation in surging air temperatures and will not survive hot summers. In this talk, I will present the development of heat-tolerant batteries for stable operation at elevated temperatures, much enhanced safety, and greatly simplified thermal management, paving the way to transport decarbonization. Profoundly, this development unveils a new design paradigm for EV batteries without having to trade-off among energy, power, safety, lifetime, and cost.
ABOUT THE SPEAKER:
Dr. Chao-Yang Wang is William E. Diefenderfer Chair Professor of Mechanical Engineering and Professor of Chemical and Materials Science & Engineering at the Pennsylvania State University. He has 220+ journal publications and an H-index of 110. He holds over 140 patents and has published two books, “Battery Systems Engineering” by Wiley and “Modeling and Diagnostics of Polymer Electrolyte Fuel Cells” by Springer. Dr. Wang is known for his innovations in batteries and fuel cells; particularly for the cross-disciplinary understanding of transport and electrochemistry in fuel cells and for pioneering a new battery paradigm with modulatable interfaces. The all-climate battery (ACB) he invented was adopted by 2022 Winter Olympics as well as commercialized by several carmakers. His latest inventions on fast charging batteries (FCB) and heat-tolerant batteries (HTB) also received widespread attention in industries. He is a fellow of National Academy of Inventors (NAI) and American Society of Mechanical Engineers (ASME), and the recipient of many awards, including the inaugural Research Excellency Award in Fuel Cells from International Association of Hydrogen Energy (IAHE). Dr. Wang’s expertise covers the transport, materials, manufacturing and modeling of batteries and fuel cells.
ABOUT THE INSTITUTE OF TRANSPORT STUDIES AT THE UNIVERSITY OF HONG KONG:
The Institute of Transport Studies, HKU was established in 2003. It is a university centre that seeks to identify research programmes as mission-oriented activities and not by traditional academic disciplines alone. As an exemplary interdisciplinary research group, the Institute is having 29 Institute Fellows, all being academic staff at the Professional level, from the Faculty of Architecture, Faculty of Business and Economics, Faculty of Engineering, Faculty of Law, Faculty of Social Sciences, and Li Ka Shing Faculty of Medicine. Apart from hosting the Distinguished Transport Lecture series, international workshops and other seminars, the Institute has co-organized the International Conference on Smart Mobility and Logistics in Future Cities with the Chartered Institute of Transport and Logistics in Hong Kong and the Transport Department of the Hong Kong Special Administrative Region.
