Under certain off-nominal conditions, Li-ion cells can generate excessive heat and gas due to the initiation of several exothermic decomposition reactions, which result in a catastrophic failure known as thermal runaway. Thermal runaway is a highly complex phenomenon involving various physical and chemical processes such as heat and mass transfer, turbulent fluid flow, and chemical reactions. In addition, thermal runaway behavior of Li-ion cells is subject to variability, resulting in different possible outcomes depending on the trigger method, state-of-charge, age, configuration it is assembled into, and environment.
The complexity of the physics involved and the variability associated with thermal runaway make it very challenging to model. This work aims to develop a systematically reduced thermal runaway modeling framework to conduct sensitivity, parametric, and variability analysis. Such a framework must be computationally efficient while considering the effects of various physics involved.
This 60-minute Webinar offers a demonstration of the efficient multi-physics solution available within a platform for this use case.
