LiB fire suppression can also be achieved by applying large amounts of water to a battery or by submerging the battery in water (Hill 2017). Both of these methods extinguish LiB fires and cool the battery, inhibiting thermal runaway and preventing re-ignition. Det Norske Veritas and Germanischer Lloyd (DNV-GL) (Hill 2017) investigated the
Developing an environment-friendly, high-cooling, non-conductive, and low-cost extinguishant has been the focus on fighting lithium-ion battery (LIB) fires. In this work, dry water (DW), a powdered material containing copious amounts of liquid water, was first studied as an extinguishant for LIB fires.
With reference to the fire extinguishing agents of lithium cells/batteries, currently they include mainly water, foam, dry powder, carbon dioxide and water mist. The results of tests have shown that the most effective are water and foam.
In fire extinguishing tests the single cell was heated up to a temperature of about 650°C and then the extinguishing agent was applied. Carbon dioxide, foam, dry powder, pure water, and water mist were used to extinguish the Li-ion cell fires. For the battery pack fire, water was used as extinguisher.
CONCLUSIONS Lithium-ion batteries pose significant fire risks and the development of fire extinguishment systems for LiBs has not been sufficiently established to provide a satisfactory level of security in the event of a fire. This paper highlights that water mist may be an effective method of extinguishment of LiB fires.
Cold Cut Systems used a cutting extinguisher (Standard Cobra lance) in the pilot study with good results. It was determined there was enough evidence to motivate further studies and tests to develop guidelines for offensive extinguishing efforts of lithium-ion battery fires. This demonstration is an activity within the scope of this work.
Screening tests for battery fire extinguishing agents were also performed. The effectiveness of an agent was evaluated through experiments on the cooling effect of fire extinguishing agents. Among the various agents, water and foam were found to be the most effective. 1. Introduction

Lithium-ion batteries are everywhere—from heavy equipment like forklifts and electric vehicles, to portable devices like laptops and cell phones. They''re lighter, stronger, and more efficient than traditional lead-acid batteries. However, they can spell trouble in the event of a fire. Determining The Type Of Fire. Not all fires are the same—but if you''re reading this blog, you probably ...
According to the characteristics of LIBs fire discussed above, an ideal fire-extinguishing agent for LIBs fire should exhibit the following properties: high heat capacity to cool the batteries and rapidly extinguish flame, electrically insulating to prevent the short circuit of the battery during fire extinguishment, a highly wettability and a ...

Why is water not effective in extinguishing a lithium battery fire? Water is not effective in extinguishing a lithium battery fire because lithium reacts vigorously with water and can generate flammable hydrogen gas. This reaction can actually intensify the fire and increase the risk of explosions.

While firefighters have used water on lithium-battery fires in the past (as it can help with cooling the battery itself), they have at times needed up to 40 times as much as a normal car fire ...
In addition, water can help to bind the resulting fumes when highly atomised. As lithium is very reactive, extinguishing a lithium-ion battery fire harbours a number of risks. Water reacts with lithium to form hydrogen and lithium oxide, which is explosive. It is therefore essential to maintain a safe distance when extinguishing a lithium fire.

The water consumption for extinguishing the lithium-Ion battery was calculated to be only 240 liters / 63 gallons. Including the time to extinguish the entire vehicle fire, a total of 750 liters / 200 gallons in total was used, in a combined effort with the Cobra cutting extinguisher and traditional fire extinguishing with water.

Why Water is Not a Suitable Extinguishing Agent. It is crucial to recognize that using water to put out a lithium battery fire is extremely hazardous. Lithium reacts violently with water, producing hydrogen gas which is highly flammable and can cause explosive results. Thus, water is not only ineffective but also significantly increases the ...
