About the Speaker
Dr. Weng received his B.S. from Huizhou University in 2007, and M.S. from Guangzhou University in 2010. He earned his Ph.D. degree from University of Hong Kong in 2015. He worked as a postdoctoral research associate at Chinese University of Hong Kong until 2017. He was a Fondazione Oronzio e Niccolò De Nora Fellow at Yale University from 2017 to 2018. He is currently a postdoctoral associate at New York University. His research interest centers on energy conversion & storage technologies and functional materials. 

Talk Introduction
Advanced electrochemical systems and functional materials affect most aspects of life today. They are crucial for technologies ranging from energy generation and storage to medical, industrial and aerospace electronics. These areas all require electrochemical systems and functional materials which satisfy increasingly demanding performance specifications. Innovation is imperative to reach these goals.
In this seminar, Dr. Weng will first present innovative electrochemical systems (i.e., air battery, hydrogen battery and vanadium-metal hydride battery) using neutralization energy. The overall reaction of such system consumes one proton and one hydroxide ion in the production of one H2O molecule, corresponding to a Gibbs energy change ΔGo=-79.89 kJ mol-1. Their advantages and working principle will also be discussed. He will then present ultra-high-energy-density aqueous and nonaqueous flow batteries using novel redox active species. The concept of flow battery, the story behind these findings and their electrochemical performance will also be shared. Finally, he will present two kinds of new carbon-based functional materials for both electromagnetic shielding and energy storage applications.
