One delayed explosion battery ESS incident is particularly noteworthy because the severe firefighter injuries and unusual circumstances in this incident were widely reported (Renewable Energy World, 2019).
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.
Other Storage Failure Incidents – this table tracks incidents that do not fit the criteria for the first table. This could include failures involving the manufacturing, transportation, storage, and recycling of energy storage. Residential energy storage system failures are not currently tracked.
