With the shift towards electrification in transportation, new challenges arise with regards to battery systems placed in electric vehicles. There is an opportunity to reduce risks associated with the toxicity of particles ejected from the gases that form during thermal runaway in lithium-ion battery cells placed in battery systems.
Learn MoreThe initial ejection material is mainly low-boiling point electrolyte vapor [21, 22], while the main ejection material is mainly H 2, CO, CO 2 and low-carbon alkane molecules [, , ]. The combustible mixture concentration emitted by the battery will be ignited when encountering an ignition source within the explosion limit range.
The ejection method is mainly through the fire detection tube inside the battery pack, i.e. fire detection tube . The tube is filled with fire extinguishing agent and placed above the safety exhaust port of the battery.
Analysis and investigation of energy storage system explosion accident. When a thermal runaway accident occurs in a lithium-ion battery energy storage station, the battery emits a large amount of flammable electrolyte vapor and thermal runaway gas, which may cause serious combustion and explosion accidents when they are ignited in a confined space.
(c) Battery ejecta combustion and explosion characteristics test. Due to the large volume of the battery and the high thermal stability of LFP batteries, it was difficult to trigger TR using traditional single-sided heating in preliminary experiments.
This is because lithium-ion batteries (LIBs) can undergo thermal runaway (TR) and rapidly propagate in the battery module under conditions such as thermal abuse, mechanical abuse, electrical abuse, and electrochemical abuse [,,,,, ].
With the advantages of high energy density, short response time and low economic cost, utility-scale lithium-ion battery energy storage systems are built and installed around the world. However, due to the thermal runaway characteristics of lithium-ion batteries, much more attention is attracted to the fire safety of battery energy storage systems.
