Thermal Runaway In Battery. Understanding the fundamental mechanisms of battery thermal runaway propagation and mitigation. A safe battery safe must not only withstand a battery fire but also the pressure of a potential explosion caused by a thermal runaway.
The energy stored in that battery is released very suddenly. Thermal runaway is a positive temperature feedback effect of a system with higher heat generation than effective cooling through the battery walls.
That Thermal Energy Increases The Temperature Of The Cell, The Increased Temperature Drives Faster Kinetics, And More Heat Is Released, Further Driving Up The Temperature.
In thermal runaway, the battery generates heat very quickly.
In Thermal Runaway, The Battery Cell Temperature Rises Incredibly Fast (Milliseconds).
This means the safe must be strong.

Thermal Runaway Begins When The Heat Generated Within A Battery Exceeds The Amount Of Heat That Is Dissipated To Its Surroundings.
Here, battery thermal runaway can lead to catastrophic explosions, fire and generation of toxic smoke.
Beyond The Battery Itself, Thermal Runaway Can Wreak Havoc On The Device It Powers.
Therefore, mitigating these risks will be essential for the mass market.
Identifying The Trigger Temperature For Thermal Runaway Is Complex, As It Varies Based On Battery Composition And Design.
