Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. This leads to damage of battery system enclosures.
The Science of Fire and Explosion Hazards from Lithium-Ion Batteries sheds light on lithium-ion battery construction, the basics of thermal runaway, and potential fire and explosion hazards.
Lithium-ion batteries can explode due to two main reasons: flammable gas explosions caused by gases generated during thermal runaways, and electrical arc explosions leading to structural failure of battery electrical enclosures. Some of these batteries have experienced troubling fires and explosions.
Some of these batteries have experienced troubling fires and explosions. There have been two types of explosions; flammable gas explosions due to gases generated in battery thermal runaways, and electrical arc explosions leading to structural failure of battery electrical enclosures.
Several lithium-ion battery energy storage system incidents involved electrical faults producing an arc flash explosion. The arc flash in these incidents occurred within some type of electrical enclosure that could not withstand the thermal and pressure loads generated by the arc flash.
Smaller explosions are often due to energetic arc flashes within modules or rack electrical protection enclosures. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.
