????Lithium ion explosion can be divided into internal short circuit fault, external short circuit fault and overcharge.
????The internal world here refers to the interior of the lithium ion cell, including the lithium ion fault caused by poor design of the external insulation layer. When the internal short circuit fault of the lithium ion battery and the electronic components cannot disconnect the control circuit, high combustion will occur outside the lithium ion battery, resulting in electrolytic liquefaction of some lithium ion batteries and large battery shell. When the external temperature of the rechargeable battery reaches 135 ??, the cost-effective diaphragm will close the small hole, the electrochemical corrosion will stop or almost stop, the current will drop sharply, and the temperature will gradually decrease to avoid explosion. However, the low micropore clearance rate or the difficulty in closing the membrane paper at the root of the micropore will cause the battery temperature to rise again, and a large amount of lithium battery electrolyte will liquefy and liquefy, which will eventually charge the battery shell, and even cause the battery temperature to ignite and explode the raw materials.
????The external short circuit fault is due to the penetration of the capillary edge of the diaphragm between copper and platinum, or the formation of lithium molecules. This tiny fibrous metal material will cause micro short circuit fault. Because the needle is thin and has a certain resistance, the current is not necessarily large. The observed condition is that the operation speed is too fast, and most of them can be screened out by lithium ion or assembly plant. At the same time, because the edge of the hair is very small, sometimes it will be burned, leading to battery recovery. Therefore, the explosion probability is not high due to short circuit fault. Such a method can lead to short battery charging time from the outside of each lithium ion power plant, and the working voltage is slightly lower than the battery charging time, but few explosion accidents occur. Statistical analysis is applied. Therefore, the explosion caused by short circuit due to explosion is mainly due to over charging. As the electrode is filled with fibrous lithium metal crystals, the penetration points can be seen everywhere, and there is a micro short circuit fault. Therefore, the temperature of the battery will gradually increase, and eventually generate lithium ion battery electrolyte vapor. In this case, whether the temperature is too high to cause ignition and explosion of raw materials, or the vehicle body is first split, causing gas and lithium metal materials to enter and produce severe air oxidation, it is the end of the explosion
????However, the explosion caused by external short circuit fault caused by overcharging does not necessarily occur during battery charging. When the battery temperature is not enough to ignite the raw materials, the existing gas body may not be able to support the cracking of the battery shell, and the customer will stop charging and take out the phone. At this time, the current heat of many micro short circuit faults will gradually reduce the battery temperature. After a period of time, the battery will explode. Customers describe each other as finding their phones very hot when they pick them up, and then throwing them away explodes.
