John Williams emphasizes that while lithium ion batteries provide a dense way to store electrical energy, they come with significant tradeoffs, particularly the risk of catching fire.
He explains that thermal runaway occurs when a lithium ion battery overheats due to defects, leading to an uncontrollable fire, which burns hotter than that of internal combustion engines.
Williams notes that vehicle design must allow enough time for passengers to exit in case of an emergency, which is where advanced thermal insulation, like aerogel, becomes critical.
George Gould describes aerogel as an ethereal and delicate material offering exceptional thermal insulation properties, crucial for mitigating the risks associated with EV battery fires.
