The frequency of mobile phone explosions seems to make the mobile phone an untimely bomb that can explode at any time. Then why does the mobile phone explode? Why does this risk increase in high temperature environments? How to avoid this?
Mobile phone explosion, generally the explosion of mobile phone battery . Expert analysis: Because lithium-ion batteries are light, cheap, and have higher energy density, they have become the main form of rechargeable batteries for digital products. However, the reason why lithium-ion batteries have an explosive tendency is a disaster caused by a process called "thermal runaway." Essentially, "thermal runaway" is an energy positive feedback loop process: elevated temperatures cause the system to heat up, and the system heats up to raise the temperature, which in turn makes the system hotter.
When the ambient temperature exceeds 60 ° C, it is often overcharged, physical damage, etc. may cause the lithium ion battery to catch fire.
Regardless of the cause, it is the cobalt oxide chemistry in the battery that goes through this reaction. If the chemical is heated to a certain temperature, it begins to self-heat and then develops into a fire and an explosion. Excessive ambient temperatures can cause permanent damage to the lithium battery, so try to avoid using lithium batteries in harsh environments.
When using a mobile phone in a high temperature environment in summer, you should pay attention to:
1. Try to avoid sun exposure and avoid damage caused by high temperature.
2, do not use the phone to talk for a long time, resulting in cell phone battery, internal circuit and earpiece fever.
3. Try not to call when charging. When the phone is charging, the battery generates heat. If you continue to use it, the heat will increase rapidly and it is easy to cause danger.
4, try to put the phone in the bag, to avoid direct damage to the body caused by the explosion of the phone.
5, use the headset cable to answer the phone. Answering the phone with the headset can reduce radiation and prevent facial damage caused by the explosion of the phone.
Develop a good mobile phone habit, which can reduce the risk of cell phone battery explosion, and choose a polymer battery phone with higher safety performance to avoid battery explosion from the root cause.
