Mobile phone security considerations

The mobile phone, like our shadow, has become an inseparable tool for people's daily work and life. We will put it aside when we work, put it beside us when walking, and even put it on the pillow when sleeping However, this "partner" we can't live without is not a security factor. At 7 pm on January 31, 2009, a mobile phone explosion occurred on Huanan East Road, Yuexiu District, Guangzhou, Guangdong Province. The year-old man's neck had a major artery rupture, bleeding continued, and he died on the spot.

Of course, this is not a special case. On June 19, 2007, a motorola phone of an electric welder in Gansu also exploded.

Through the above incidents, industry insiders analyzed that the main culprits in mobile phone explosions worldwide are batteries. Why does the battery explode?

1. The battery itself, due to internal defects in the battery, the battery itself exploded without charging or discharging.
2. Long-term overcharging of batteries. Lithium batteries may discharge a large amount of current momentarily, causing spontaneous combustion or explosion under special conditions such as temperature, humidity, and poor contact.
3. Short circuit. This chance is very small. However, if the mobile phone is placed near the high temperature and flammable objects, it is very likely to cause an explosion.

Therefore, people in the industry call for the supervision of the production of mobile phones and batteries. In addition, the majority of users should also store the mobile phone correctly, and do not place it on objects that are prone to explosion due to high temperatures.
