Abstract: The characteristics of lithium iron phosphate battery fires in energy storage systems both at home and abroad are analyzed, and typical accident cases of various faults are listed. The differences between energy storage battery fires and automotive power battery fires are compared. The advantages and disadvantages of current research on fluorine-based fire extinguishing agents, water-based fire extinguishing agents, aerosols, liquid nitrogen, and carbon dioxide fire extinguishing technologies at home and abroad are summarized. The research progress on the combustion and explosion mechanism, explosion prevention and explosion suppression technologies of large-capacity lithium iron phosphate battery energy storage systems at home and abroad is summarized. The viewpoint of "intrinsic safety to prevent fires", "early warning and active regulation to avoid thermal runaway", and "fire suppression and explosion suppression to ensure safety as a last resort" for the safety defense of lithium-iron battery energy storage systems is proposed, providing technical guidance for the prevention and control of fire and explosion in the domestic lithium iron phosphate energy storage industry.

Key words: lithium-iron batteries, lithium iron phosphate, extinguish the fire, explosion suppression
