If the cell phone battery is deformed after falling, will it explode?

Most cell phones today use lithium batteries, and the direct cause of lithium battery explosions is the overheating and expansion of lithium batteries.

Four possible causes of cell phone explosions.

First, the lithium battery electrolyte cannot leak, but the reaction of lithium will produce gas. Once there is gas, the internal pressure will increase, just like a pressure cooker. Ordinary cell phone batteries have a safety valve for this purpose. When the pressure is high, it will be safely discharged to prevent the battery from viciously exploding. However, if the design is not good and the lithium battery does not have such a safety valve. at all, it will be very dangerous.

Second, even if a safety valve is installed, if the quality is not good, an explosion will occur. In addition, the plaThe steel blades of counterfeit and substandard cell phone batteries are very thick. If the pressure relief valve is of poor quality, once an explosion occurs, the broken steel plates will be very powerful.

Third, the lithium reaction of mobile phone batteries is carried out on two boards. If the design is not good, the crystals will get bigger and bigger with the chemical reaction. is broken, one layer, short circuit and large current will occur, resulting in sudden high heat and then explosion.

Fourth, the third situation is generally considered when designing lithium batteries. There is a safety circuit in the battery to ensure that it prevents an explosion in the event of an external short circuit. However, if this safety circuit is present. poorly designed, excessive tension will occur.

In addition, a high temperatureee is an external trigger.
