The Secret of Mobile Phone Security: Lithium Battery VS Explosion

Do you know that?/You know what? Do you know that?/You know what? The mobile phone itself will not explode, and the real "time bomb" is actually the lithium battery inside! Having said that, I have to mention the li-polymer of Apple's mobile phone. This kind of battery basically won't explode, but at most it will ignite! Next, let's reveal the truth about the explosion of the mobile phone.

Problems with the battery itself

Due to internal defects, some batteries may explode without charging or discharging. In order to avoid this situation, it is very important to choose a good battery, such as a polymer battery.

Long-term overcharge

The maximum allowable voltage of the battery itself is too high or too low, which may lead to explosion. Therefore, the overcharge voltage of the protection IC should be controlled at 4.30V to ensure the safety of the battery.

shorten

Although the possibility is small, it cannot be ignored. Choosing protection IC with short-circuit protection function, high-quality MOSFET and strict production technology are the keys to prevent short-circuit.

Safety tips

Choosing mobile phones, batteries and protective equipment, checking and replacing batteries regularly and avoiding long-term overcharge are all important measures to protect the safety of our mobile phones!
