If your phone's battery drums, can you continue to use?

We now make a lot of electrical appliances, including the battery of your smartphone, using a lithium-ion battery. And the charging and discharge behavior of the lithium ion battery is actually a chemical reaction. When charging, the lithium atom of the positive electrode will lose an electron with a negative result into a lithium ion, and the lithium ions passed through the base liquid to the negative electrode, and then store.

When discharge is discharged, it is reversed, releases a lithium ion, and it is reduced to a lithium atom. A small amount of gas will occur during this process, so sometimes it will find extremely small bullets. However, the charging current is too large, often overcharge (such as a battery is only charge for 3 hours, but it is charged for 12 hours or even longer) will exacerbate the occurrence of gas, so that the internal pressure of the battery has caused a bulging phenomenon.

At this time, the battery drum is extremely obvious. What is the solution? Some people think that the gas is the battery drum bag, and the mouth allows the gas to disperse, then solve the drum bag. In fact, in my personal opinion, this is a more dangerous behavior, can't do this.

Battery drums, the only decision is to replace new batteries. The first is because the battery is capped, it is very dangerous to explode, because the metal is very lively, exposed to air is extremely easy to oxidize. Secondly, the battery is capped, the capacity will lose, more than 50%, the amount of battery is not enough to go to the head.

The cause of the battery explosion is important to short circuit. There are many reasons why short circuits, such as external mechanical damage, causing damage to the membrane, possibly in the battery manufacturing process, mixed metal dust, piercing the diaphragm, causing a short circuit. When short-circuiting, the positive and negative contact, the current is increasing, there is a lot of heat, and the battery is closed space, thereby exploding, and then there is a possibility of fire.

2. Other reasons have the voltage control failure, causing overtake (this is better than a balloon, originally set a pressure, it will not break within the pressure range, the results of control measures have been invalid, constantly blow in, natural It is blown), and the high voltage will cause the electrolyte to decompose, so that the battery is bulging, accompanied by heat. 3.

It is also possible that the battery is working in a high temperature environment, or the heat of mobile phone structure is unreasonable, and the heat when the high-energy-consuming software is running (such as the glory of the king) causes the battery to heat the battery to cause complex chemical reactions in the battery. It is possible to cause drums or thermal out of control. So how can you make sure that the battery is safe to use, extend the service life? 1.

Try to use the original battery now a lot of mobile phones are one machine, the battery is not detachable, and many people will choose to change the mobile phone when the battery is fine. If it is a detachable battery, or if you don't want to change your phone, it will be changed, you will not be greedy, this must be a penny, if you don't buy the original, you have to buy a regular manufacturer, don't buy it. Some of three unfilves are harmful to others, but they also buy charging treasure is similar.

2. Using the original charger Original charger and your mobile phone battery must be matched, including output voltage and current, the focus is in which control circuit boards can control the voltage to reach the cutoff voltage, stop charging, not overcharge. If you don't buy an original charger, you have to buy a regular, big brand of General Charger.

Although there are now many standards to unify the parameters of each brand charger, but it is still risky, such as some mobile phone's battery is not suitable for fast charge.
