thermal runaway

Fire behaviour of NMC Li-ion battery cells

The main features of Lithium-ion (Li-ion) batteries are high energy and power density, which make this storage technology suitable for portable electronics, power tools, and hybrid/full electric vehicles. Moreover, during conditions that lead to failure, Li-ion battery cells could undergo into a process called thermal runaway, which has resulted in numerous fire accidents. Thermal runaway implies a rapid increase in battery cells temperature, accompanied by the release of flammable gases. These flammable gases could be easily ignited by the battery’s high temperature, resulting in a fire.
