Abstract

You are reading this page likely with the help of a lithium-ion battery. Since the first commercialization in 1991, lithium-ion batteries have revolutionized our ways of powering phones, laptops, and cars. Paving the way to this technology is the pioneering work by the trio awarded this year’s Nobel Prize in Chemistry, John GOODENOUGH, M. Stanley WHITTINGHAM, and Akira YOSHINO. A solid-state physicist, a chemist, and a corporate engineer, the three never worked together but inspired each other to tame highly reactive materials in a safe and long-lasting device. They deliberately crafted intercalation electrodes that took in lithium ions without large structural changes, and paired carbon and a transition metal oxide to make the energy-dense battery that we still use today. With their contribution, lithium-ion batteries have become indispensable parts of our society, and they are playing critical roles in our transition towards renewable energy.

Biography

Prof. Chen Qing received his BS in Polymer Science from Zhejiang University and his PhD in Materials Science from the Arizona State University. Prior to joining the HKUST in 2016, he had his postdoctoral training on redox flow batteries at Harvard University. He is currently an Assistant Professor in the Department of Mechanical and Aerospace Engineering and the Department of Chemistry at HKUST.

Prof. Chen’s current research interests include micro-structural evolution in electrochemical processes and their application in batteries. His research group applies materials science and electrochemistry to understand and control structural evolution at nanoscales. The group also uses the same set of knowledge in the design of electrochemical devices, particularly for energy storage.
