Increasing global adoption of EVs is putting the spotlight on safety features for these next-generation vehicles. There are some inherent risks involved with the use of lithium-ion batteries, as instability in one cell/battery can increase the temperature of the cell and create an explosion and/or fire, causing irreparable damage. Considering the presence of many cells in proximity within an EV battery, an instability in one cell can easily propagate to adjacent cells, causing a cascading event that could result in a massive exothermic event. Automakers and suppliers are on a quest to reduce the frequency of these events to make electric vehicles safer and more adaptable, while several global authorities are also developing safety standards to mitigate the severity of these events.

In this presentation, we will review the status of regulations, consider several current material solutions designed to mitigate propagation at the cell and pack level, and discuss what future trends in development are needed to improve the efficacy, suitability and versatility of such material solutions to the dynamic nature of the cell chemistry and pack architecture.
