Biography

Mr. Lei Zhang is currently a PhD student at The Hong Kong Polytechnic University. He received his B.Eng. degree in Civil Engineering from Jiangnan University in 2021. He received his M.Sc. degree in General Structural Engineering from Imperial College London in 2022. His research focuses on thermal runaway of lithium batteries, thermal runaway suppression, and thermal runaway warning. His work ranges from small-scale fire experiments in the laboratory to full-scale battery pack and storage tank experiments. He also conducts research on coupled multi-physics field simulations, and the use of artificial intelligence tools to process and provide predictions for multi-dimensional sensing signals. Through these efforts, his goal is to help better understand the thermal hazards of batteries and seek safer, more efficient, and cleaner lithium battery technologies.
