AI Technical Summary
In battery components, thermal runaway events can lead to the propagation of heat, flames, and high-pressure gases, which can cause fatal safety problems. Existing technologies are unable to effectively suppress or delay this phenomenon.
The barrier uses a hydrogel containing polymer and water as the heat-absorbing material. The outer packaging melts at high temperature and releases the heat-absorbing material to absorb heat and extinguish the flame. The barrier can be used stably in various forms and does not chemically react with the components inside the battery assembly.
It effectively delays and suppresses thermal runaway events, improves the safety and structural stability of battery modules, is suitable for various forms and spatial configurations, and prevents heat propagation and flame spread.
