What is Thermal Runaway? (Introduction)

OREE
ESRI

In lithium-ion cells, the movement of electrons and lithium produces electricity. The process of charge and discharge is normally accompanied by a small amount of heat. In ideal conditions, the heat is able to dissipate from the cell. In thermal runaway, the lithium-ion cell generates heat at a rate several times higher than the rate at which heat dissipates from the cell.
