地点:苏州大学阳澄湖校区交通楼一楼大报告厅

报告人:原迎春教授,美国凯斯西储大学教授,

讲座内容:

电动汽车被认为是下一代的主要的清洁与环保的交通工具。然而电动汽车的电池作为动力源需要耗费大量的材料和能量去生产,同时电池的损耗和替换也进一步增加电动汽车的环境负荷和成本。这个报告将主要介绍利用电池的损耗模型、热传输和电荷传输的去综合分析在不同地区和不同外界环境下的电池的使用寿命,为政策制定者提供更好的参考。

Abstract:

Electric vehicles (EVs) are widely recognized as clean alternative to conventional vehicles for reducing greenhouse gas emissions from ground transportation. However, the lithium ion batteries (LIBs) used in current EV are gravely concerned on such sustainability issues as short battery life and uncertain environmental impacts, which are rooted in the battery material chemistry, manufacturing processes and operating conditions. In this seminar, comprehensive electrochemistry modeling of lithium ion battery performance will be presented, integrating the lithium ion mass diffusion, charge transport and heat transfer, as studied on the typical lithium manganese oxides (LMO)-Graphite lithium ion battery which are widely used in such EVs as Nissan Leaf and Chevrolet Volt. The battery charging/discharging behaviors, internal resistance and stress/strain evolution under actual battery operating conditions are mathematically modeled and experimentally validated to understand the battery degradation during the battery charging/discharging cycling operations. Finally, the battery life under actual EV operating conditions in each state of U.S. are numerically predicted and the battery-governed greenhouse gas emissions from the EV operations are accurately determined. These results can be useful in support policy-making for sustainable deployment of electric vehicles in future.
