Although it does not happen very often, the explosion of mobile phone batteries is still known. Why is the cell phone battery exploding? Let's talk to everyone today.
Currently, common consumer electronic products such as smart phones and tablets use lithium batteries internally. In fact, although the battery of mobile phone and tablet is referred to as lithium battery, it refers to Lithium-ion battery. The lithium element itself has the characteristics of small volume, high energy density, active chemical activity, and insignificant memory effect. Very much loved. The name of the lithium battery refers to the dry batteries of No. 3 and No. 4 that can only be used once and cannot be charged.
Question 1: The mobile phone battery will really explode?
The answer is, yes. The battery stores energy through the "cell". When overcharged or over-discharged, it may break through the diaphragm in the inferior battery core, causing the battery to be short-circuited, causing high temperature and high pressure and causing an explosion. Therefore, the process of charging the mobile phone is the most prone to explosion.
Question 2: Under what circumstances will the mobile phone battery explode ?
There are three main reasons for the explosion of mobile phone batteries:
(1) Battery quality
In fact, the current battery explosion situation is caused by the use of non-original batteries. The inferior battery that was sold by the unscrupulous businessman as a genuine battery will cause the battery to explode because of excessive raw material impurities, unqualified manufacturing process, and inaccurate design related to battery safety protection.
(2) Long-term overcharge of the battery core
In the case of long-term charging, if the battery is overcharged or the current is too large, it may lead to high temperature and high pressure, and the safety of the buried battery may be buried. Lithium-ion batteries may cause excessive transient currents due to special temperature, humidity, and poor contact conditions, and battery explosion or spontaneous combustion may occur.
(3) Battery short circuit
When the battery is in a high temperature state, or subjected to impact or metal friction, it may cause an electric short circuit and an explosion.
Question 3: How to properly charge the phone and prevent the battery from exploding?
(1) Select the original battery
Most of the reason why the battery will explode is because the battery is of poor quality, so the original battery is the safest. Because the original battery will be covered with a layer of safety mold outside the battery, when the battery pressure is too large, the safety mold will burst and release the pressure, and the protection battery will not explode, but the non-original battery may miss this safety measure. .
(2) Check the battery condition at any time
When your mobile phone battery is replaceable, you can pay attention to whether there are scratches on the battery or the impact of the impact. In this case, it is best to avoid using it again to reduce the battery explosion. Probability.
(3) Do not rush after charging after damp or water
If the iPhone cannot replace the battery, in a humid environment, or after accidentally entering the water, it is best not to rush to charge, it is best to send the water to check first to avoid a short circuit and cause an explosion.
