If the Pacific Automotive Network ternary lithium battery catches fire, a carbon dioxide or ABC dry powder extinguisher can be used to extinguish the fire. When thoroughly inspecting the fire, do not come into contact with any high voltage components and always use insulated tools for inspection. ABC dry powder fire extinguishers, halogenated alkyl fire extinguishers (such as Hailun fire extinguishers), and water-based fire extinguishers can all be used.
1. Whether you can use water to check the battery status, the main thing is SOC status.
If it is 100%, it is not recommended to use water. Because high-charge batteries are prone to explosion when exposed to water (to be precise, high humidity), especially 18450 batteries which are common in the market.
If it is a device containing a normal battery or a used battery, vYou can safely use water as a coolant.
2. The choice should be based on the environment, which is the environment in which lithium batteries catch fire. For the initial extinguishing of lithium batteries (such as cell phones) in everyday situations, ABC dry powder fire extinguishers, halogenated alkyl fire extinguishers (such as Hailun fire extinguishers), and water-based fire extinguishers can all be used for continuous cooling. , a large amount of non-flammable liquid (such as water) should be used.
For some special lithium batteries, a more reasonable disposal is to remove other flammable substances and wait until they burn completely.
The principle of paying attention to water use is to pay attention to a large amount. The effect of ice is much less than that of water. At the same time, we must do atbe careful. the fact that there are no live installations or equipment in the surrounding area.
In addition, the actual fire extinguishing should always follow the principle of convenience. That is, if the lithium battery is confirmed to be smoking and burning, use any extinguishing agent or its substitute at hand. as soon as possible.

How long does it take for a cell phone battery to explode and smoke
1. Use a fire extinguisher Calm the flames. Usually after that the fire is extinguished and the battery continues to smoke. Most fire extinguishers can achieve this effect. 2. Since lithium batteries will reignite if not cooled, it is very important to use plenty of water to cool the batteries. 3. It is best to move the burning battery outdoors and call the fire brigade toto take care of.
Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses non-aqueous electrolyte solution. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M.S Whittingham proposed and began studying lithium-ion batteries. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.
What the person asking the question wants to ask is how long does it take for a cell phone battery to explode or for smoke to come out of the cell phone? It won't explode. There is no necessary relationshipbetween smoking on cell phones and the explosion. Theoretically, the battery will not explode if it smokes. However, this thing is already very unstable, it is full of carcinogenic substances. Please keep it away from people and wait 10 minutes until it cools properly. . abandoned. Common causes of cell phone battery explosion:
1. Causes of the battery itself. Due to internal battery defects, the battery itself explodes without being charged or discharged.
2. The battery core is overcharged for a long time. Lithium batteries can discharge instantly and generate a large amount of current under special conditions or environments such as temperature, humidity and poor contact, causing spontaneous combustion or explosion.
3. Short circuit. This possibility is relatively small. In addition, the fact that consumersMMuters placing their cell phones near high temperature or flammable objects can also cause explosions.
