内容简介：

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 EVs are gravely concerned on their sustainability issues such as short battery life and uncertain environmental impacts, which are rooted in the battery materials, manufacturing processes and operating conditions. In this seminar, multiphysics electrochemical modeling of lithium ion battery performance will be presented, integrating the battery manufacturing parameters and operating conditions, for studying the degradation of the typical lithium manganese oxides (LMO)-Graphite lithium ion battery which are widely used in Nissan Leaf and Chevrolet Volt such EVs. The battery charging/discharging behaviors, internal resistance rising and cycling capacity loss 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 sustainable manufacturing and adoption of lithium ion batteries for EVs, and also can be transformed to study next generation battery technologies in future.
