Lithium-ion battery fire extinguishers

Nowadays, Lithium-Ion Battery Fires are considered to be a life-threatening risk arising as an unintended, but dangerous side effect of the energy transition of last 10 years. Lithium-ion Batteries, used in e-bikes, mobile phones, laptops, game consoles, etc. can catch instantaneous fire by means of a malfunction. These malfunctions can be caused by:

1. Overcharge

2.Too rapid charging

3. Damage by physical impact/shock

4. Heat

5. Internal short circuit

6. Manufacturing defect

A malfunctioning Lithium-Ion battery can lead to an internal chain reaction, which is called a Thermal Runaway. The malfunction causes the temperature inside the battery to increase to a point that a chemical reaction is started inside the battery. This chemical reaction produces even more heat, which drives the temperature higher, causing further chemical reactions that create more heat. These temperatures cause toxic and flammable gassing of the battery, leading to an explosive fire that is so hot and vicious that it is nearly impossible to extinguish. This chain reaction is called a thermal runaway.

Hydrogel Lithium-ion battery fire extinguishers

 A few years ago, greek manufacturer MOBIAK have introduced an innovative Extinguisher Series for Protection against Lithium-Ion Battery Fires. Reminding that the Extinguishing Agent used for this Series is the Vermiculite, a natural mineral-based fire extinguishing agent in Gold/Brown Color which is made from naturally occurring Vermiculite.  Although the existence of this Extinguisher Series, MOBIAK has continued its research and relevant studies for Lithium-Ion Battery Fires. The result is the todays’ announcement of a Brand-New Extinguisher Series for Protection against Lithium-Ion Battery Fires using another Type of Agent called HYDROGEL, that is an innovative fire extinguishing agent based on a revolutionary new technology. With this unique, patented, new approach, no Fluorine chemistry is necessary and there is no compromise made in fire extinguishing effectiveness, environmental friendliness and human safety.
 
Safe for environment

1. Hydrogel contains ZERO PFAS

2. Non-toxic for the environment

3. Recyclable

4. Fluorine Free

 Safe for humans

1. Hydrogel will not decompose into dangerous substances, as many other fire extinguishing agents do. This means that Hydrogel is safe to use for the person who is extinguishing the fire.

2. Hydrogel is not hazardous for humans, does not cause skin irritation, etc.

3. Although Hydrogel contains more than 95% water, it can be safely used on electrical equipment (up to 1000 Volts)

For extinguishing of Lithium-Ion battery fires, Hydrogel has proven to be a superior product as it is characterized as a thermal runaway blocker. Hydrogel will extinguish the flames in the shortest time. Due to its ability to stick to hot surfaces, the Hydrogel will apply maximum cooling of the exploded battery cells. By doing so, the temperatures will drop rapidly and prevent other nearby batteries to go into a thermal runaway leading that the thermal runaway is blocked by the Hydrogel and further risk of fire is eliminated.
 
On the below you can view photos regarding the Successful NTA 8133 Fire Suppression Test held at KIWA Laboratory in the Netherlands – the Test has been successful for 600Wh Battery Capacity.

The Models presented through this Newsletter are the is the 6Lt and the 9Lt Portable Fire Extinguishers – by the 1^st Trimester is 2024 we will additionally Inform you about a New Portable Extinguisher of 2lt Capacity as well as for 25Lt and 50Lt Trolley Fire Extinguishers, covering all the possible demands in this Extinguisher Type.
