Wed, 26 Jul 2023 00:34:01 -0700

What Is Thermal Runaway

When it comes to the definition of battery's thermal runaway phenomenon, it is the major risk that one of the cells inside the module or system is out of control and generate heat by itself. After that, this will lead to smoke, fire, gas leakage and particulates coming out. Generally, the single cell is able to dissipate the heat but except for the thermal runway situation. In that, the lithium cell could have more chances of generating heat vloume than the heat dissipating one.

How To Prevent Thermal Runaway In Batteries

Thermal runaway is a risk for damaging batteries. So we should know to prevent this happening. When a cell's temperature increases at a ramp rate over 20 degrees centigrade per minute, then it is in a thermal runaway situation. So don't let battery expoure to the extreme high temperature for a long time.
