Summary

Operando monitoring batteries under diverse working conditions is essential to build next-generation batteries with better quality, reliability, lifetime, and safety. This talk will introduce the pressing need to track the underlying physicochemical processes within the batteries and compare various candidate sensing technologies. I will focus on the optical fiber sensors, ranging from fiber Bragg grating to evanescent wave spectroscopies. For fundamental research, I will showcase their unprecedented capabilities of capturing delicate electrochemical processes in solid electrolyte interphase formation and battery aging. Application-wise, this talk will also share our explorations in a few scenarios, from thermal management to state estimations. As the outlook, I will envision futuristic smart batteries by converging cross-disciplinary efforts from materials science and optics to artificial intelligence.

Dr. Jiaqiang HUANG

Assistant Professor
Sustainable and Environmental Thrust
Hong Kong University of Science and Technology (Guangzhou), China

Dr. Jiaqiang HUANG joined Sustainable Energy and Environment (SEE) Thrust, Function Hub, HKUST(GZ) in January 2022. He graduated with his Bachelor of Mechanical Engineering from Shanghai Jiao Tong University with the Shanghai Excellent Graduate Award in 2013 (Advisor: Prof. Xinmin LAI). He then obtained his Ph.D. in Mechanical Engineering from the Hong Kong University of Science and Technology in 2017 (Advisor: Prof. Jang-Kyo KIM and Prof. Baoling HUANG). He received his postdoctoral training at the Hong Kong Polytechnic University (with Dr. Biao ZHANG) and Collège de France (with Prof. Jean-Marie TARASCON). Dr. Huang’s research interests center around batteries, particularly at the interface between novel optical fiber sensors, battery material/chemistry, and artificial intelligence. His research group is committed to building smarter and more sustainable batteries with better quality, reliability, lifetime, and safety.
