Improving EV safety by identifying thermal runaway mechanisms in high nickel-based Lithium-ion batteries
A research team led by Professor Jongsup Hong of the Department of Mechanical Engineering has developed an original technology to improve the safety of lithium-ion batteries based on high-nickel cathode materials, which have been receiving increasing attention for improving the range of electric vehicles amid the rapid transition to vehicle electrification and the widespread adoption of electric vehicles. The research was published in the Chemical Engineering Journal (Impact Factor: 15.1, Top 3.2%, Volume 471), a top journal in the field of thermal and reaction engineering, in July 2023. In this paper, we identified the thermal runaway mechanism of lithium-ion batteries based on high-nickel cathode materials by considering the phenomena occurring at each electrode individually through a combination experiment between materials, and developed a reliable model to increase the utilization of the mechanism, paving the way for improving the safety of electric vehicles.
