4月25日上午，我院拟于线上举办“Understanding of battery issues”专题讲座，届时欢迎各位老师同学参会交流。以下是讲座详细信息：
讲座内容：
Lithium-ion batteries are one of the critical momentums of our current mobile society. With the further development and application of increasingly high energy density batteries and large capacity battery packs in electric vehicles, cellphones, laptops, and large-scale energy storage systems, the consequences of battery safety issues now become significant threats. Internal short circuits (ISCs) and thermal runaways (TRs) are typical battery safety issues where electrochemistry, thermal, and mechanics are strongly coupled. Interdisciplinary endeavors are in pressing need to address these safety issues. In this talk, multiphysics modeling and characterization at cell level (~102 mm) will be highlighted to provide a mechanistic understanding of the nature of triggering and evolution of ISCs. In the meantime, a machine-learning combined with physics-based modeling will be introduced to achieve faster computation with higher accuracy. Results provide new insights into multiphysics behaviors in battery safety issues and offer engineering-ready modeling methodologies for the next-generation battery design, evaluation, and monitoring.
