Evidence has shown that the key to successful fire protection of lithium-ion batteries is suppressing/extinguishing the fire, reducing of heat-transfer from cell to cell and then cooling the adjacent cells that make up the battery pack/module.
Due to lithium-ion batteries generating their own oxygen during thermal runaway, it is worth noting that lithium-ion battery fires or a burning lithium ion battery can be very difficult to control. For this reason, it is worth understanding how lithium-ion fires can be controlled should a fire scenario happen.
As lithium-ion battery fires create their own oxygen during thermal runaway, they are very difficult for fire and rescue services to deal with. Lithium-ion battery fire control is normally only achieved by using copious amounts of water to cool battery cells.
In the case of fires involving large arrays of lithium-ion battery cells, like those used in electric vehicles, lithium-ion battery fires are normally only controlled and extinguished when the fire and rescue service deliver a large amount of water to the burning materials for a significant amount of time.
One method of handling fires in Lithium-ion bateries is to contain the batery and fire to prevent it spreading to other cells or materials. This can be a solution for small portable batery powered devices.
The design of oxygen reduction systems should be determined through fire testing but, to date specific test data has not been published in relation to Lithium-Ion battery fires. Oxygen Reduction Systems can prevent Flame Stacks but this can lead to excess toxic & flammable fumes leaving the enclosure which then need to be dealt with.
