Why does smart phone battery explode? How do I prevent that?

With the great technological development, especially in smartphones, we see a race between companies trying to provide phones with new ideas and advanced capabilities. But this may be at the expense of the batteries, as we find them heating up and may explode. We lived with many of these problems. What makes smart phone batteries carry these risks and what are the ways to prevent them?

First of all, any type of battery has the potential to explode, even though lithium-ion batteries all carry risks. And we don't mean to scare you from your phone, as these problems may never happen to you. But you must know the causes of these problems and prevent them.

Take a look at that clip of lithium batteries under XNUMX-minute heat exposure:

But outside the lab, how do these batteries explode in the real world? Here is the sequence of events that occur inside lithium-ion batteries before and during the explosion:

◉ One of the battery areas begins to get very hot, either due to a contact or “shortening” in the charging circuit, or some external cause.

◉ The chemical reaction inside the hot zone begins to generate heat and spread it to other areas of the battery, known as electrolyte heat.

◉ This heat causes the expansion of the electrolyte, which is an aqueous solution of sulfuric acid consisting of positive hydrogen ions. When these materials expand due to heat, they cause the battery casing to explode.

 ◉ When this liquid comes out from the battery, it is very hot and flammable. It usually burns or melts the surrounding phone case or causes damage to anything beside it.

This reaction known as "thermal escape" sounds somewhat dangerous and terrifying, but there is one fact that makes you relaxed and reassuring, which is that battery makers pay attention to the security aspect, especially in the manufacture of lithium batteries, which reduces the possibility of such damage. Among these security precautions:

◉ Non-flammable materials are added to the electrolyte or the materials from which the battery is made to paint.

◉ Building electrical circuits to protect from these hazards, disrupting them, and preventing the source of the danger from other areas, especially if the cell pressure exceeds the safe limits. One example is "Fuse".

◉ The presence of safety openings through which gases are released if the matter enters into a real danger.

In addition to the above security precautions, there is a message on the phone informing you of the high temperature and that the phone must be switched off. Or until the battery stops working.

Cases causing batteries to explode

 Drop and damage the battery

One of the serious problems that we encounter on a daily basis is the fall of phones, and there is no doubt that this negatively affects the battery. We think about the damage that happened to the phone first and last and forget that there is a battery that may be damaged as well.

How can you tell if a battery is damaged?

Take a look at the battery, in case you have any of the following problems, consider having it replaced immediately:

Bloating

◉ distortion

Frequent overheating.

If you watch and avoid using your battery for these signs of damage then you are safe.

1- Hot temperatures and environment

While your phone's battery has safety guarantees, it is important to keep it away from high temperature in the first place. It should be noted that there are natural things that make your phone overheat, so use them with caution:

◉ Running graphics-intensive apps or games that put a heavy load on the GPU or CPU.

◉ Applications or widgets run continuously and without interruption while using or not using the phone.

◉ If the Wi-Fi or cellular data connection is weak. Where the phone is working hard to get coverage or signal.

◉ Long-time calls.

Also, working in hotter environments and exposing your phone to direct sunlight, this is dangerous for the phone and its battery.

If the above factors do not pose hazards, they can contribute to rapid battery wear.

And the process of charging the phone under these circumstances can contribute to an increased risk, otherwise the phone will heat up naturally during charging.

There are several ways to keep your phone cool and avoid these problems:

◉ Remove the phone cover when charging.

◉ Keep the phone out of sunlight whenever possible.

Never leave your phone in the car when it is in the sun.

◉ Do not charge your phone while it is in your pocket, under a cover, or in a place that traps heat.

Use an unreliable charger

The use of accessories that are not original or from unreliable sources, this is undoubtedly very dangerous for your phone and its battery, and if you are working to save, then buying these products wastes money and makes you lose your phone or at least one of its internal components, forcing you to go to maintenance centers and spend more money.

The phone has been wet

Lithium burns out in contact with water or water vapor. With batteries being airtight, and phones becoming waterproof, we need to be careful.

Battery holes

You can add that point to the previous point, because the lithium reacts with both water and oxygen, and if the battery is exposed to that, you will see a little smoke, a bad smell, or a full explosion. Watch the following video to see the effect of a hole in the battery.

So, we warn again that you should check the phone well after it has fallen

Notice: Smartphone batteries have become safe to a great extent, and what happens from explosions to phones are only a few cases on the fingers of one hand, and this does not prevent caution and caution. May God protect you and us.
