As electric vehicles (EVs) become more widespread, ensuring lithium-ion battery safety during collisions is increasingly important. Mechanical impacts can cause internal damage, leading to short circuits, thermal runaway, or explosions. Protective enclosures help reduce deformation, but effective design demands accurate failure predictions. This webinar presents a comprehensive approach for modeling mechanical abusive loads on EV batteries, incorporating experiments, material characterization and the Sahraei Failure Criterion—a universal failure model based on microstructural simulations of the electrode-separator assembly. Model validations will be presented across various cell types and loading scenarios in commercial software such as Ansys LS-Dyna and Altair Radioss. Combined with multi-scale simulations, this framework supports the development of safer, more resilient battery systems for EVs.
This webinar will focus on the following key topics:
• Experimental Methods for Material Characterization
• Multiscale Modeling from Components to Cells and Battery Packs
• Short Circuit Prediction with Sahraei Failure
• Applicability to Pouch, Cylindrical and Prismatic Cells

Battery Selection Tutorial Course 1/3: Selecting your Cell and Cell Manufacturer(s)
After designing your product, you need to ensure the battery with which you are operating it will ensure the right performance and lifetime. When deciding this, narrowing down which chemistry (e.g. Li-ion, lithium primary, NiMH, etc.) best fits your product and which form factor are some of the first steps. Choosing a cell design (high-power vs. high-energy, for example) is another step and finally, finding the right cell manufacturer to fabricate your cells and packs. This webinar is the first in a three-part series on designing the right battery for your product. It will cover many of the key differences in chemistries, form factors, and cell designs and other best practices.
This webinar will focus on the following key topics:
• Choosing the right chemistry for your application
• Choosing the right form factor
• Choosing cell designs (e.g. high power vs. high-energy)Presenter

Battery Selection Tutorial Course 2/3: Beyond the Standards: Device-Specific Testing
After choosing your cell and manufacturer (Part 1 of this series), most likely, they will have passed the tests of various standards organizations. However, depending on your operating environment, you may need to go above and beyond the baseline to ensure your product operates as intended. This webinar is Part 2 in a three-part series and will review a variety of factors to consider in your device-specific testing, including designing tests to predict the outcomes of various user-abuse scenarios, understanding the mechanisms of gas generation, capacity retention based on different voltage windows, and what happens if you need to cycle your cells outside of their operating range (outside in an Arizona summer or Minnesota winter, for example).
This webinar will focus on the following key topics:
• User-abuse scenarios to prevent against
• Causes and effects of various gas generation mechanisms
• Voltage limitsPresenter

Preventing Li Ion Battery Failures From a Manufacturing and Design Perspective
How can you be proactive and make sure your cell supplier is the right one and you don’t end up with thermal events and field failures? Is it enough to qualify a cell manufacturer according to industry standards? The answer is that the majority of compliance based testing is related to abuse tolerance. However, the vast majority of field failures do not occur under abuse scenarios, but happen under normal operating conditions due to manufacturing flaws or design and system tolerance issues that cause internal shorts. In this webinar, you will learn about common lithium ion battery failure modes and how to be proactive in preventing these.
This webinar will focus on the following key topics:
• Gain an understanding of lithium ion battery failure mechanisms and the pathway to thermal events
• Learn how cell design impacts battery safety and reliability
• Learn the basic steps in a lithium ion cell manufacturing process, and how the process controls affect safety and reliability
• Come away with a checklist to qualify your cell manufacturerPresenter
