Conclusions 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.
It's not even a linear process where one hazard follows another and as a result, lithium-ion battery fires are unpredictable and the nature of the risk changes during the incident. Paul regularly gives presentations to fire and rescue services, sharing his knowledge about battery fires.
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.
When a lithium-ion battery fire breaks out, the damage can be extensive. These fires are not only intense, they are also long-lasting and potentially toxic. What causes these fires? Most electric vehicles humming along Australian roads are packed with lithium-ion batteries.
