Why charge, easy to cause the explosion of lithium-ion batteries fire accident?
It might make most people have a headache, want to use lithium-ion batteries, but worry it will explode.
Recently a lithium battery deflagration fire small video circulated in WeChat group: a man sitting in the living room to play mobile phone, all of a sudden explosion happened are charging the storage battery, lithium battery, moment the room smoky, only hear continuous deflagration.
In recent years about the lithium battery fire news pertaining to fire.
In April 2020, in the morning in Shanghai xujiahui, putuo district, almost at the same time, a pair of fires caused by electric lithium battery, two accidents caused another injury.
Last year on May 5, guangxi guilin lijiang river of fire, is electric charge in the last two years the biggest casualties accident, a total of five deaths, 38 people were injured.
In 2019, for example, shantou city, guangdong province, October 20, a rental building, first floor against a wall charging electric cars burst after continuous noise, fire smoke quickly filled with the whole of the corridor.
And after using dry powder fire extinguisher to put out, still continue to deflagration, before and after the last 2 minute always cannot be completely extinguish fire.
In the face of so frequent lithium battery fire, many people may all have no serious thought about this question: once the lithium battery deflagration is found, how can we put out a fire?
Some people may think, there is fire, spray with a fire extinguisher!
Yes, definitely need a fire extinguisher.
Lithium-ion batteries, however, is a kind of high energy solid matter, although its flame is very easy to put out, but its internal energy is excited by high temperature, has not been released, the temperature is very high, will continue to burn again soon, bang!
So, actually met lithium battery deflagration, what to do with us?
If the battery reaches a high enough temperature, leakage and release the electrolyte, electrolyte must be flammable liquids.
This will need to use a lot of water to cool the battery and put out the fire, because there is no grounding, dc and ac system firefighters can safe water as the main agent, and there is no risk of electric shock.
ABC dry powder fire extinguishers will not put out battery fire.
Firemen should be avoided in the fire, or relief operation any direct contact of internal high pressure components, this potential, leading to an electric shock.
To sum up, in the event of a lithium battery deflagration, we can use the fire extinguisher (first
Dry powder, water base will do)
The ignition of the external flame extinguished.
As much as possible and then water for cooling, the process can be long, be patient!
Since lithium-ion battery internal temperature is high, energy sustained release after burning, so, in this case, the conventional air extinguishing method doesn't work, such as fire blanket, sand, etc. , it lead to poor heat dissipation caused greater deflagration.
