Lithium-ion batteries are commonly used in electric vehicles and other electrical devices. However, their thermal behavior can pose safety challenges. Thermal abuse can lead to fires, known as thermal runaway, with high heat release rates and the emission of toxic gases. This paper discusses thermal runaway in lithium-ion batteries during electrical vehicles production, emphasizing the need for early fire intervention. Five experiments were conducted to validate lithium-ion batteries thermal runaway and assess organic and inorganic-based extinguishing agents. The inorganic quenching agent could rapidly cool the lithium-ion batteries surface temperature to 75 degrees C within just 50 seconds, delaying the onset of thermal runaway. The organic-based extinguishing agent failed to extinguish the lithium-ion batteries fire even after three interventions in the thermal abuse test. However, the inorganic-based extinguishing agent successfully extinguished lithium-ion batteries fires that had entered thermal runaway with only one portable extinguisher. Fire blankets can also be effectively used in electric vehicles fires. Unlike organic extinguishing agents, a single tube of the inorganic quenching agent is sufficient for thermal runaway.
