The objective of this study was to compare the effectiveness of fire extinguishing agents for suppressing lithium-metal and lithium-ion battery fires and preventing thermal runaway propagation. Tests were performed in a 64-cubic-foot test chamber with a sealable door.
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.
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.
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.
4. CONCLUSIONS. The hot plate tests and the battery fire tests showed agreement with each other. This showed that the capacity of an extinguishing agent to stop the thermal runaway propagation of lithium batteries may be accurately determined by the cooling effectiveness of the agent.
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 battery fires are triggered by the release and ignition of flammable organic solvents, gases, and plastic components within the battery. These fires involve flammable materials and release toxic compounds like Hydrogen Fluoride, Hydrogen Cyanide, and Sulphur Dioxide, posing significant risks during the fire and post-fire cleanup. Fires often begin at the cell level due to …
A report from tests made public by the Swedish Civil Contingencies Agency (MSB) shows that a cutting extinguisher can safely put out a battery fire in a very short time, with minimal use of water and without the risk of re-ignition.
When extinguishing a lithium battery fire, the amount of water used is important. Due to the chemical reaction, this type of fire requires more water than conventional fires. Generally speaking, you should use at least two gallons of water for each gallon of fuel involved in the fire. This will ensure that all of the heat energy is extinguished and prevent any further …
To actively stop thermal propagation in a lithium-ion battery, the exothermic reactions occurring within the battery cells must be slowed down and stopped. One way to do so is with internal cooling of the cells inside the battery. Several tools on the market can be used to extinguish fires in lithium-ion batteries
There are several tools on the market that can be used to extinguish fires in lithium-ion batteries and to facilitate the disposal of the batteries after fire incidents. The purpose of the tools is to speed up the extinguishing effort and provide a more efficient extinguishing.

Research and practical applications have confirmed an effective method for using Cobra to manage lithium-ion battery fires in electric vehicles. Cobra interrupts an ongoing propagation by internally flooding the battery with water, which cools it and prevents further thermal runaway in unaffected battery cells.

Lithium-ion battery fires are commonly caused by a chain reaction known as ''thermal runaway'', which occurs when a lithium-ion battery cell produces more heat than is being dispersed. Lithium-ion batteries contain flammable materials such a flammable electrolyte which breaks-down into various flammable and toxic gases, along with some oxygen, during ''thermal …
