报告人简介

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 innovative research on batteries and fuel cells; particularly for pioneering a new battery paradigm with modulatable states and interfaces. The all-climate battery (ACB) he invented was adopted by 2022 Winter Olympics as well as commercialized by several carmakers. 

报告摘要

Smaller, faster-charging batteries are the answer to affordable and sustainable electric vehicles for everyone, everywhere. Critically, battery fast charging must work in tandem with high-temperature stability of cycling and storage in order to provide high safety and low degradation and survive in hot summers. Thus there is a simultaneous need for greater than 4C charging and stable cycling and storage at greater than 75oC. In this talk I will show how the dual target can be realized with innovation in both electrolytes and cell structures. Profoundly, our development points to a new paradigm of battery materials without having to trade-off among fast charge, safety, lifetime, and cost.
