Battery and EV Fire Safety

 

Facing the crisis of fossil fuel depletion, global warming, and climate change, Li-ion battery is perceived as the most promising solution for the alternative energy source. However, the frequent occurrence of battery fire poses a severe threat to public safety, becoming a significant obstacle for further developing and applying electric vehicles (EVs). Compared with conventional fire, the fire hazards exhibited by Li-ion batteries are immensely disparate in initiation route, spread rate, duration, toxicity, and suppression.

Our research focuses on the thermal runaway characteristics of Li-ion batteries under various conditions and the fire protection technologies of the battery pack for electric vehicles. Through experiments and numerical simulations, we are designing new materials to mitigate battery fire and a sophisticated fire protection strategy for battery energy storage systems. The research outcomes will not only support the future development of safe high-energy batteries but also help lay a good scientific foundation for the emerging development of fire-safe EVs.
