Especially after the Samsung Galaxy Note 7 incident, the biggest nightmare of all smartphone, tablet, smart watch users was the battery explosion. So, why do smartphone batteries explode? In this regard, as a user, there are points that you should pay attention to both when purchasing and using the device.
Smartphone batteries are like bombs that we carry in our pockets and often tuck them under our pillows at night. Batteries, which store electrical energy and use our devices for certain periods of time, are getting bigger every year. Of course, they are becoming more efficient, but since the energy need of smartphones is increasing day by day, we spend efficiency on new technologies. Although the number of innovations related to batteries is increasing day by day, unfortunately there is an unsolved problem: They are ready to explode at any moment.
So why do batteries explode, what makes them so risky or increases the likelihood of them exploding? All together today, what is commonly found on our smartphones of lithium-ion batteries We take a closer look at why they explode. This curiosity will lead us to the chemical secrets inside the phones that we never leave with us.
Why do smartphone batteries explode?
- Errors caused by the production process
- Errors caused by the design process
- User-generated errors
- Charger related errors
- Cost-related errors
Errors caused by the production process:
Lithium-ion, in short, Li-ion batteries, has a flammable and organic solvent feature among them. two electrodes with an electrolyte layer includes. Under normal conditions, these two electrodes should not touch each other thanks to the layer between them, so that a problem does not arise. However, due to a minor manufacturing defect, 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. Because in Note 7s, a short circuit occurred in the batteries due to the electrodes touching each other as a result of sheet crushing, the reaction of the chemical substances in the battery accelerated due to the rapidly increasing 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 makes it more susceptible to explosion, even if there is no problem in its production.
Errors caused by the design process:
We want all our mobile devices to be small, thin, but with all kinds of technology inside, batteries don’t run out. Designers do their best in line with user requests, but sometimes in smartphones that will meet these demands, the ventilation gap to balance the battery temperature is not enough, the battery heats up and explosion is inevitable. This situation is more common in replica phones, where design is generally not given much importance.
In fact, 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, devoid of protection, are in our pockets ready to explode. Nevertheless, manufacturers take adequate precautions in this regard.
User-generated errors:
Of course, sometimes the answer to the question of why the phone batteries explode is necessary to look for the user. To give a simple example; your phone if you overcharge or if you charge it below 0 degrees, lithium metal will accumulate on the negative electrode, heat up and eventually explode inevitably. The problems experienced in the case of overcharging have been solved by most manufacturers in software. However, we can say that the risk is valid, since such software supports are not offered on replica phones.
Long-term use also has a negative effect on phone batteries. You can make sure that there is a problem with the battery by showing the device to the technical service at regular intervals. Because the problem battery swells and you can’t see it anymore because the back cover of the phones doesn’t open. than the original to be cheap Using second-hand or counterfeit batteries will also cause explosions.
Charger related errors:
Now wherever we turn our heads, we see either a USB cable or a charger. Moreover, their prices are quite cheap compared to the originals. Why is it cheap? Because current controls and insulation controls that should be in a charger are not done and none of the legal obligations are fulfilled.
All lithium-ion batteries have a certain energy storage capacity and a certain recharge time. current strength unclear what A charger will damage the battery. Likewise, when you connect a device that does not have a fast charging feature to a high current fast charging adapter, it will definitely be harmful.
Cost-related errors:
Perhaps the most basic answer to the question of why smartphone batteries explode is cost. The user uses a cheaper charger and the battery is damaged. Maybe the manufacturer a few cents profit it tries to save on a material and it results in exploding batteries with a manufacturing defect.
Before relying on sub-market devices with lithium-ion batteries. You should think again. Unusual processes and material restrictions can be made to reduce the cost. Do not take such a risk just because you will make a few cents profit like the manufacturer company.
smart for you phone batteries We answered the question of why it explodes and as a user you need to pay attention We explained the points. Although the Samsung example is an exception to this issue, it is known that large manufacturers are generally sensitive to the issue and fulfill their legal obligations.
