To easy understating of ENCLEA by Q & A

• Class-A: General fire – general fires such as wood and plastics.

• Class-B: Flammable liquids, oils, etc.,

• Class-C: Electrical Fire – Electrical fire, non-conductive is key performance.

• Class-D: Metal fires – caused by highly active metal powders.

• Class-F: Kitchen fires – kitchen

• A secondary battery that generates and accumulates electricity through a chemical reaction of lithium oxide.

• It is composed of 4 elements: anode / cathode / separator / electrolyte.

• The performance of LIB is highly dependent on the anode.

• Usage of LIB; Electric vehicles, smartphones, laptops, small home appliances & tools, golf carts, energy storage devices(ESS), emergency power supplies(UPS), etc.

• Lithium-ion batteries are very vulnerable to heat and shock.  In particular, if excessive current flows, the temperature of the battery rises, or the separator is damaged due to outside impact, the internal electrolyte, anode, and cathode will react chemically unstable and cause a fire, mainly occurred by their own heat.

• LIB fire commonly caused by manufacturing defects, outside damage to the separator, physical impact, overcharging, short circuit, etc.

• LIBs, themselves contain a large amount of oxygen in electrolyte, and are composed of a large amount of flammable materials. Thus, it has the property of burning itself by its own oxygen supply, without outside oxygen supply.
  
  

• Due to the high energy density, fires are extremely large.

• Lithium ion battery fires are the mixture of Class-A (general fire) & Class-C (electrical fire).

• First: fast cooling is necessary to prevent the rapid spread of heat to neighboring cells (thermal runaway).

• Second:  Fire extinguishing agent should penetrate into battery cells or battery modules & packs. Even if the fire is extinguished outside, there must be a quick penetration effect because secondary ignition and fire occur due to the high temperature inside cell itself.

• Third: To secure fire extinguishing activities, non-conductivity should be guaranteed. Otherwise, all firefighters should be fully equipped with non-conductive gears including clothes, gloves, shoes. But still, if you apply conductive firefighting agent, for instance water, all loses of valuable data, malfunction or permanent damage of expensive facilities will be definitely caused.

• Lithium-ion batteries contain lithium oxide, not metal (lithium), so they are not metal fires. Therefore, Class-D fire extinguisher can’t extinguish a lithium-ion fire.

• Class A, B, and C powder type fire extinguishers do not put out lithium-ion battery fire. The reason for this is that it does not have the ability to penetrate inside cell pack, so it can extinguish the fire on the outside for a short time, but it can’t extinguish the fire that is continuously running around inside cell pack. The same goes for gas-based fire extinguishers. Instant fire extinguishing seems to be possible, but it does not provide fundamental put it out, surely cause 2nd and 3rd iginition.

• In addition, gas-type fire extinguishers have suffocating function so that they can cut off oxygen inflow from outside, but lithium-ion battery fires continue to burn since lithium ion in electrolyte form, itself, contains oxygen.

• For LIB fires, fire extinguishing blankets is a concept of extinguishing a fire by covering it and blocking oxygen, but it is also not recommended because it causes a continuous fire by 2nd and 3rd ignition, highly likely causing huge explosion.

• ENCLEA is a non-conductive liquid. We have passed 16 times of non-conductive test in local authority and in front of key members of Samsung Electronics, Hyundai Motors and many province governments. We have test report proving; with 100,000 volts flow, only 0.1mA is allowed at a separation distance of 90cm.

• The absence of electrical short circuits means that it is possible to effectively extinguish fires while protecting expensive electronic equipment and all the valuable data in the equipment.

• Moreover ENCLAR agent is Non-toxic. Ordinary gas-type fire extinguishing agents produce oxides that are very dangerous to the human body when extinguishing fires. (Fluorinated gas & PFAS)  Non-toxicity of ENCLEA is clearly proven by Korean patents, U.S. patents, and China patents.
