Modeling Thermal Runaway and Abuse in Batteries - Archived

One of the main factors influencing the safety of Li-ion batteries is thermal runaway and its cascading effect through the pack. Thermal abuse conditions also have an adverse effect on battery function and can lead to catastrophic damages. To predict thermal runaway, it is necessary to account for several different physical phenomena, including chemical reactions within the cell, heat transfer at the cell and pack level, the structural design of the pack, and fluid flow in the battery pack's cooling system.

If you would like to learn how to use multiphysics modeling to accurately predict thermal runaway and simulate thermal abuse conditions in batteries, tune in to this webinar.

We will discuss:

• Causes of thermal runaway in batteries
• How to model different thermal runaway scenarios, including internal and external short circuiting as well as mechanical abuse
• How to model internal short circuiting including processes such as lithium plating and gassing
• Thermal analysis of batteries and battery packs by coupling losses from high-fidelity and lumped models
• How to compute crucial safety parameters, including the maximum temperature occurring during thermal runaway, the time to reach thermal runaway, and heat propagation patterns
• How to analyze the effects of filler material and battery configuration on temperature distribution in a battery pack
• How to analyze different battery cooling mechanisms, such as liquid cooling, air cooling, and phase change material cooling
