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 large-scale lithium-ion energy storage battery fire incidents have involved explosions. 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.
Deflagration pressure and gas burning velocity in one important incident. High-voltage arc induced explosion pressures. Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.
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. Smaller explosions are often due to energetic arc flashes within modules or rack electrical protection 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.
When the battery temperature exceeds about 150°C there is a large risk for thermal runaway. Once thermal runaway has been initiated, either the cell or its safety valve will burst and release toxic gas. As thermal runaway propagates, more battery cells will fail to generate more smoke and toxic gases.
