China and the United Nations have mandated that battery electric vehicles provide a 5-minute window for passengers to exit the vehicle after detection of thermal runaway. While the 5-minute goal is a step forward for passenger safety, it may not go far enough. Single-cell thermal runaways that propagate to the module, pack, or vehicle level will, even at very low incident rates, dampen public acceptance of BEVs. A better goal, for both the consumer and the industry, is to stop thermal propagation entirely.
Cell-to-cell thermal barriers play a crucial role in thermal propagation prevention strategies. Battery engineers are tasked with designing a solution that not only optimizes a vehicle’s performance, but also meets critical safety requirements. This 60-minute Webinar discusses the ways in which aerogel-based thermal barrier materials can help achieve these goals—and do so within realistic space, weight, and cost constraints.
