AI Technical Summary
Technical Problem
Existing lithium-ion battery modules are prone to thermal runaway events that can trigger a thermal chain reaction, leading to the propagation of gas or flames, which may result in explosions or fires.
Method used
A battery module structure was designed, including a module housing and an emission unit. The emission unit consists of an outer shell and an inner shell, which are made of different materials. The inner shell has different thicknesses and shapes to stabilize the emitted gas and prevent heat propagation.
Benefits of technology
It effectively suppresses the propagation of thermal runaway events, ensures stable emission of gases or flames, prevents thermal chain reactions between battery modules, and improves safety.
