Lithium-ion battery fires differ from other types of battery fires in several key aspects related to their intensity, causes, and hazards:
- Aggressiveness and Intensity: Lithium-ion battery fires are often more aggressive and difficult to control compared to other battery fires due to their high charge density and multiple flammable components. The cells contain a small volume but pack a lot of power, making them lightweight and portable but also capable of violent explosions and rapid temperature spikes above 932°F within seconds.
- Thermal Runaway and Chain Reactions: When a lithium-ion battery fails, it can undergo a thermal runaway, a rapid, uncontrolled reaction where one cell’s failure triggers adjacent cells to also fail and ignite. This cascading effect can produce violent bursting, hissing, release of toxic, flammable, and explosive gases, intense self-sustaining fires, and even metal projectiles.
- Hazards: Li-ion battery fires release toxic smoke and vapors, emit intense heat, and have the potential for explosion, which makes them particularly hazardous. These fires can involve radiation, chemical, electrical hazards, and the generation of metal fragments, which are less typical or less severe in other battery fires.
- Safety and Occurrence: Despite their risks, lithium-ion batteries are generally safe when properly stored, charged, and discarded. Their fires are usually due to failure or damage situations.
In summary, lithium-ion battery fires are typically more intense, rapid, and hazardous than fires caused by other batteries due to their energy density, flammable materials, and susceptibility to thermal runaway leading to chain reactions. These factors make lithium-ion fires a significant safety concern and challenge to firefighting efforts compared to other types of battery fires.
