3D modeling of the ejection and combustion of vented gases during the thermal runaway of Lithium-ion battery cells

The rapid growth in the use of electric vehicles has led to a strong demand for batteries. Lithium-Ion batteries are currently the dominant technology, as they offer good performance, in particular high energy density. Nevertheless, these batteries can be subject to thermal runaway, which can lead to the destruction of the vehicle. It is therefore important to develop adequate numerical tools to predict and prevent this type of accident.
