Is an iPhone battery explosion toxic?

　　The explosion of an Apple mobile phone battery does not mean that there is gunpowder or explosives inside. The explosive power of the battery is equivalent to a one-time release of energy. The internal sealing of the battery is better. Due to the gas generated during the charging and discharging process and the temperature rise, the internal pressure becomes larger. When the pressure reaches the strength of the shell, the battery will rupture; if the pressure rises slowly, the pressure will drop after the battery shell ruptures To a low level, the battery will only rupture and will not explode; but if the pressure rises sharply and the casing ruptures, the pressure is pushed out from the crack at a greater speed, and it may explode. Therefore, it is forbidden for Apple mobile phone batteries to be put into fire, and cannot be charged or discharged with excessive current. Even if the original battery is beyond the range of the protection system, it may cause the battery to short-circuit and cause fire, explosion and other accidents.

　　Apple mobile phone batteries are lithium-ion batteries. Early battery safety is not high enough, and they often burn and burst. With the improvement of technology, in order to improve lithium-ion batteries, active ingredients that can inhibit lithium are added to the batteries, such as Cobalt, manganese, etc., make lithium-ion batteries have the characteristics of high safety, high efficiency, and long life. However, when such batteries explode, the smoke produced by them is toxic and has limited harm to the human body.
