Battery 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. 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 a reliable fire suppression technology and a sophisticated battery fire protection strategy. 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 electric vehicles.
