Abstract

This study adopted the external heating method to generate the lithium ion battery spontaneous combustion, spraying HFC-227ea and CO2 to conduct fire suppression explosion test, and researched the explosion suppression effect of the gas suppression on lithium ion battery. The results show that HFC-227ea and CO2 mainly inhibit the explosion of the lithium ion battery through the method of cooling. The HFC-227ea and CO2 can extinguish the open flame, reduce the combustion temperature and weaken the explosive strength. The combustion temperature of lithium ion battery undergoes three stages: initial growth, sharp rise and decay. It is necessary to take measures to extinguish fire and explosion in the initial growth stage.
