How to properly extinguish lithium-ion battery fires?

The correct method of fire extinguishing with lithium battery How to distinguish between lithium battery and fire when an electric vehicle catches a fire? One of the dangers of a lithium battery fire is that you cannot visually judge whether the fire has been extinguished. If it is not completely extinguished, it may burn again. There is a related video on Youtube, you can search for FAALithiumFire u200bu200b(FAA's lithium battery fire). This video was taken to show the crew how to put out a computer fire on the plane. How to put out a lithium battery fire? Use a fire extinguisher to put out the flame. Usually when this is done, the fire is extinguished and the battery is still smoking. Most fire extinguishers do this. But there is also a second, because lithium batteries will burn again, if they are not cooled down, it is important to use a lot of water to cool them. Water at any time. It is best to move the burning battery outside and call the fire department to deal with it. Smoking is harmful to health. Do not breathe fumes. The following are measures to prevent lithium batteries in the battery charging rack of a bicycle shop: 1. If all batteries are charged on a special charging rack, the electric bicycle shop will be safer. 2. The charging stand should have large and light wheels, and should be made of non-flammable materials. Put it at the door. Nothing can stop the charging station from pushing out the door. 3. If there is a fire, the first reaction is to push the charging stand out of the room. The battery, charger and smoke alarm are all placed on the charging stand. There is only one extension cord on the charging stand, so there will be no other interference when the charging stand is pushed out of the door. When the charging stand is pushed out of the door, the power plug should be easy to pull out. Install a timer on the power supply on the charging stand to prevent charging at night. Have a 10-pound ABC and a Class D fire extinguisher on hand. When the fire is out, you can cool it down with water. (Hose, bucket, fire extinguisher, etc.) Battery type and fire risk of electric bicycle. Commonly used lithium battery fire situation: Sealed valve-regulated lead-acid battery (SVRLA) This battery has the same appearance as the battery used for emergency lighting and computer uninterrupted power supply. Excessive charging with a constant current charger can cause explosion and fire. In rare cases, car starter batteries have the same problem. In particular, hydrogen is released, and in some cases, hydrogen can cause an explosion. Unless the charger is powerful enough, it is not easy to prevent prolonged charging. The US power industry does not use nickel-cadmium batteries, which were also used in Europe and Japan a few years ago. It is generally considered non-flammable. But they are toxic, which is why Europe and Japan do not use them. Ni-MH batteries are also rare. Some new bicycles and many old bicycles have them. Usually not flammable, but if it is short-circuited, it will release hydrogen; if it is in a limited space, it will explode. Lithium manganese oxide battery (LiNiMnC002) is a widely used battery. If properly assembled and managed, such batteries will not catch fire. But there is still the possibility of fire, especially if cheap products are used or products are misused. The most common problem is that it takes too long to charge with the wrong charger. This battery is more compact and cheaper than the other batteries on the list. So it is the most popular electric bicycle battery. Lithium iron phosphate batteries (lifep04 also known as LFP and LIPO) are generally considered to be the safest battery among lithium batteries. This battery is not easy to burn and rarely catches fire. These batteries are heavier than lithium manganate batteries, so their use on electric bicycles is limited. The LiC002 battery has not been used in electric bicycles by any reputable company. This battery has the highest energy density and is commonly used in mobile phones and other consumer electronics products. However, the large-size battery of electric bicycles is not stable enough. Confusingly, some lithium manganese oxide batteries are described as nickel diamond lithium manganese oxide batteries, but they are not what I call lithium cobalt oxide batteries.
