Are lithium-ion batteries a fire hazard?

As lithium-ion (Li-Ion) batteries become ubiquitous in devices ranging from smartphones to electric vehicles (EVs), their high energy density poses new fire safety challenges, including the risk of thermal runaway which can lead to intense fires.

What are the NFPA 855 fire-fighting considerations for lithium-ion batteries?

For example, an extract of Annex C Fire-Fighting Considerations (Operations) in NFPA 855 states the following in C.5.1 Lithium-Ion (Li-ion) Batteries: Water is considered the preferred agent for suppressing lithium-ion battery fires.

Is there a standard test commodity for lithium-ion batteries?

There is currently no standard test commodity for lithium-ion batteries. Thus, standard exposed expanded Group A plastic commodity was used in listing tests. Further testing of the Model LB11 HSW sprinkler, beyond the listing, was conducted with lithium-ion batteries as described in this Reliable Bulletin 084 (Link below):

How do you stop a lithium ion battery fire?

Water is considered the preferred agent for suppressing lithium-ion battery fires. Water has superior cooling capacity, is plentiful (in many areas), and is easy to transport to the seat of the fire.

What is a'smaller' Li-ion battery?

The standard applies to Li-ion battery systems with a total capacity higher than 20 kWh within the potential fire area. (Smaller devices are typically consumer devices that are evaluated by other dedicated standards.) buildings near exposures. Remote location is defined as 30.5 m or more from other buildings, equipment, and structures.

What does SoC mean in a lithium ion battery?

The term State of Charge (SOC) describes the energy (typically referred to as capacity) available for use in the battery. A fully charged battery has an SOC of 100%, while a fully discharged battery has an SOC of 0%. Figure 1. Basic principles and components of a Li-ion battery.
