What should I do if a lithium battery catches fire? How to put out the fire?

What if the lithium battery catches fire? As the application of lithium battery becomes more and more widespread, it has been used in many electronic products such as mobile phones, computers, mobile power supplies, electric vehicles, and has become an indispensable item in people's life and entertainment. However, if used and handled improperly, lithium batteries may also pose a risk of fire, even threatening people's lives and industrial safety. I will tell you why lithium batteries are a fire hazard, and what to pay attention to when you extinguish them. The important risk of lithium battery fire is that the lithium battery after fire and explosion will cause thermal runaway due to overheating, so once the battery cell of the battery pack is thermally runaway due to overheating, it will have enough heat to form adjacent cells when a fire occurs. , A new thermal runaway, in turn, caused the entire battery to catch fire. Therefore, regarding the lithium battery fire, the fire extinguishing process is divided into two steps: 1) Extinguish the open flame caused by the lithium battery fire. 2) Cool the lithium battery to prevent thermal runaway. When the lithium battery is on fire, it is absolutely not allowed to use rescue materials such as fire blankets to test the pressure to fight the fire, because this will cause the heat to not be lost and accelerate the development of thermal runaway. Lithium battery fire extinguishing steps are as follows: 1) Use halon or water resuscitation device to extinguish open flames. 2) Then pour water or non-alcoholic liquid on the lithium battery to fully cool it down. Special attention should be paid to the fact that some people may think that it is better to use ice to cool down! Wrong, very wrong, you must remember to not use ice for cooling. Practice has proved that using ice will increase the phenomenon of thermal runaway. Only water or non-alcoholic liquids can be used for cooling. never forget.
