Smartphone batteries are like bombs that we carry in our pockets and often tuck under our pillows at night. Batteries, which store electrical energy and use our devices for a period of time, are getting bigger every year. Of course they are becoming more efficient, but as the energy demand of smartphones increases day by day, we are spending efficiency on new technologies. Although the number of innovations related to batteries is increasing day by day, unfortunately there is an unsolved problem: They could explode at any moment.

So why do batteries explode, what makes them so risky or increases the likelihood of them exploding? All together today, which we often find on our smartphones of lithium-ion batteries We look at why they explode. This curiosity will lead us to the chemical secrets in the phones that we never leave with us.

Why do smartphone batteries explode?

Errors caused by the production process:

Lithium-ion, or Li-ion batteries for short, has a flammable and organic solvent function. two electrodes with an electrolyte layer includes. Under normal circumstances, these two electrodes should not touch each other thanks to the layer between them, so that no problem arises. However, due to a small manufacturing defect, such as in the case of the Samsung Galaxy Note 7 years ago, this layer may not be able to separate the two electrodes.

What happened on the Galaxy Note 7 can happen to any phone. In Note 7s, because the batteries shorted out due to the electrodes touching each other due to the breaking of the sheet, the reaction of the chemicals in the battery accelerated due to the rapidly rising temperature, causing swelling and explosion after a while. Samsung has eliminated this problem in its later models. However, any phone with pressure on the battery will make it more prone to explosion, even if there is no problem in manufacturing.

Errors caused by the design process:

We want all our mobile devices to be small and thin, but with all kinds of technology in them, batteries do not run out. Designers try their best in accordance with users’ requests, but sometimes in smartphones that meet these requirements, the vent to balance the battery temperature is not enough, the battery heats up, and explosion is inevitable. This situation is more common with replica phones, where design generally doesn’t give much importance.

The smaller a battery and the higher its energy capacity, the more dangerous it is. Old phone batteries were pretty thick and didn’t have much capacity, and ktheir foreheads protected them. Today, thin batteries full of power, bereft of protection, roam around in our pockets, ready to explode. Nevertheless, manufacturers take adequate precautions in this regard.

User generated errors:

Of course, the answer to the question of why the phone batteries explode sometimes requires finding the user. To give a simple example; your phone if you pay too much or if you charge it below 0 degrees, lithium metal will accumulate on the negative electrode, heat up and eventually explode inevitably. The problems with overcharging have been solved by most manufacturers with software. However, we can say that the risk is valid as such software support is not offered on replica phones.

Prolonged use also negatively affects the phone’s battery. You can determine if there is a problem with the battery by regularly showing the device to technical support. Because the problem battery swells up and you can’t see it anymore because the backs of the phones don’t open. than the original be cheap Using second-hand or counterfeit batteries also causes explosions.

Charger related errors:

Now everywhere we turn our heads we see a USB cable or a charger. In addition, their prices are quite cheap compared to the originals. Why is it cheap? Because current checks and insulation checks that should be in a charger are not done and none of the legal obligations are met.

All lithium-ion batteries have a certain energy storage capacity and a certain charging time. current strength unclear what? A charger will damage the battery. Likewise, connecting a device without a fast-charging function to a high-current fast-charging adapter will certainly be harmful.

Cost-related errors:

Perhaps the most basic answer to why smartphone batteries explode is the cost. The user is using a cheaper charger and the battery is damaged. maybe the manufacturer a few cents profit it tries to conserve material and it results in exploding batteries with a manufacturing defect.

Before relying on devices in the lithium-ion battery submarket. You have to think again. Unusual processes and material constraints can be created to reduce costs. Like the manufacturer, you don’t take such a risk just because you are going to make a profit of a few cents.

smart for you phone batteries We answered the question why it explodes and as a user you have to pay attention We have explained the points. While Samsung’s example is an exception to this, it is known that major manufacturers are generally sensitive to the issue and comply with their legal obligations.
