Is cell phone battery explosion toxic?

The so-called battery explosion does not mean that there is gunpowder or explosives inside. The energy is released at a time, and the equivalent of its explosive power can be calculated; the reason for the explosion is because of the inside of the battery with better sealing, because of the gas that appears during the charging and discharging process. And the temperature rise causes the internal pressure to increase. When the shell strength cannot withstand the increase in internal pressure, rupture may occur. When the pressure increase rate is slow, and the pressure drops to a lower level immediately after the shell ruptures, it may just be the shell rupture. It is not an explosion, and there is nothing that can hurt people; but if the internal pressure increases sharply for some reason, after the shell ruptures, the remaining pressure may push the broken part out at a greater speed, which may cause an injury; so The use of batteries emphasizes that they should not be put into fire (causing a rapid increase in temperature), and operations such as charging and discharging with excessive current cannot be performed, because even if the protection system cannot withstand abnormal use, accidents will occur: including internal short-circuits. Cause a fire. Lithium-ion batteries are an improved product of lithium-ion batteries. Lithium-ion batteries have existed a long time ago, but lithium is a highly active metal. It is not safe to use. It often burns and bursts during charging. Later, there are improved lithium-ion batteries. The addition of ingredients (such as cobalt, manganese, etc.) that can inhibit the activity of lithium elements makes lithium batteries truly safe, efficient and convenient, and the old lithium-ion batteries are basically eliminated. As for how to distinguish between them, it can be identified from the battery's logo. Lithium-ion batteries are Li and lithium-ion batteries are Li-ion. Now, the so-called lithium-ion batteries used in notebooks and mobile phones are actually lithium-ion batteries.
