In the future lithium-ion battery fires will be considered a bread and butter fire, but for now it isn’t. As more devices utilize this type of power, the rates of lithium-ion involved fires will increase. As we'll discuss in this course, firefighters must be well-informed of the hazards, understand thermal runaway, and be able to recommend ways to limit the severity of these types of fires. This course will also discuss the concerns we have with lithium-ion batteries, review the cell structure, and examine what causes failures in these cells.
