Sometimes we hear some poor stories about the explosion of the bateries of smartphones or smartphone's battery catching fire, sometimes causing dangerous harm to their users. You must have heard about the poor galaxy note 7's explosion which proved as a nightmare for their users as well as company. Samsung then recall it's devices afters concerns raised. These explosions were caused by the defective batteries of note 7's devices. Actually the size of note 7 batteries were became larger than normal due to the manufacturing defects and this causes the unfortunate explosions than made out this device, a grenade. Here I am discussing some causes of explosion of these lithium - ion batteries and hiw you can protect yourself from these casulities.

Lets discuss.......................................................
Causes of Explosion:
Lithium - ion batteries seldom bulge or explode, but when, actually there are two reasons of Explosion of these Lithium- ion batteries. The first cause is the puncture, which may happen by dropping your phone or by applying the applicable pressure to your phone's batteries. And this dropping causes the breaking of the internal seal, which prevent the mixing of those dangerous chemicals present in Lithium- ion batteries. This breaking of seals causes the mixing of internal chemicals that are present in your batteries, which causes an internal short circuit. It also leads to bulging/swelling of your smartphine batteries and cause potential explosions. Alternatively speaking, the cheaper batteries are more prone to these fatal incidents. Actually in cheaper lithium ion batteries, due to the manufacturing defects some small metal particles inside it might come into contact with other parts of the cells which leads to a dangerous short circuit causing the problem of Explosion.

While in Galaxy note 7 devices, we hear some reports that suggest that the explosion is caused when the device is charging, which indicates our second major culprit of Explosion, heat. Excessive heat sometimes leads to the burning of safety seals (which prevent the mixing of chemicals), which leads to the internal short circuit within the battery and causing the explosion. However these matters only occur at vey high temperatures. So these are very rare cases of Explosion. It mainly caused when your battery is faulty. Overcharging is also an issue, which is caused when the batteries are receiving more current than safety levels, causing them to overheat. That's why company tells you to use the supplied charger within the package or if by any reasons you are unable to use the provided charger then you must use a good comapny's charger to charge your device not the cheapest one.
Excessive heat in one area of the battery causes "thermal runaway". This phenomenon happens when an area of the battery does not cool down properly and quickly enough, which results in a chain reaction that results in the generation of more and more heat. In simple words, excess amount of heat causes a chain reaction that accelerates the heating of batteries. At last this leads to a deadly explosion or fire.
Basically, high quality batteries includes a safety barrier that prevent these dangerous chemical chain reactions from taking place.
Relation between Charging and heating:
There are the number of causes of excessive heating in the smartphone and it's battery. Now-a-days, the invention of fast charging technologies are now forcing more injection of electric current in smartphone's batteries. Since in every transfer of power heat is produced,so when you transfer more power the more heat will produced. So in today's generation of smartphone batteries, some of this heat - loss occur at the battery itself whereas, some heat will also lost in fast charging power conversion and power management circuitry, which is located in the next to the battery compartment. This could leads to more heat at the one end of the battery than the other end.
Oh sure! We also blame the processors for this incident. Since due to the presence development of technologies the size of data and apps have also increased, which in terms caused the increase in workload of smartphones processors. Do in this way, the processors inside the smartphones are producing more and more heat than the hades of second and third generations. This furthur leads to the generation of more heat in today's smartphones which could furthur leads to increse in the tempreature of the battery.
"Since the more powerful processer is, the more power it will draw from the battery which in terms leads to more heat production inside the battery. It also makes the transfer of heat more difficult from the body of a smartpbone".

Protecting Yourself from these Dangers:
It is difficult to say that when and where your smartphone will say "fire in the hole" and you would be in the hands of The Grim Reaper after a while. But there are some signs which says that your battery is damaged and could explode. These signs include a hissing sound, popping or swelling of your batteries.
So let's know about some safety measures now.......................
1. Stop charging your phone if it becomes too hot:If you think that your smartphone becomes too hot during the charging. Allow your phone to cool down before charging it again and must take out mobile covers during the charging cycle as it allows to escape heat easily.
2. Stick to supplied chargers or good comapny's chargers: You must use the suoplied charger which is provided by the company out of the box because it will provide a safety amount if voltage to your battery during the charge or if your charger I'd worm out them must use a good company's charger. If you are using a device with USB Tyoe-C port or Quick charge technology, then it might be a wise decision to use the provided cable out of the box.
3. Don't Charge your smartphone in the bed: It is fun to watch videos and playing games in your smartphone on the bed before you fall asleep, but it will be a nightmare to roll over on your phone and let it overheat. Also it is a habit of some people that they charge their phone by keeping them under the pillow, I don't know why, but please avoid this because it will leads to more heat production and also explosion.
4. Be midful of where to charge your phone:Avoid chatting your phone for long periods of time in really hot places, like on the car's dashboard, next to the radiator or in hot Sunny days and in direct sunlight.
5. Don't let down your phone's battery level too low: It is a common misconception that, "you must charge your phone when its battery level is below 15%". Please don't do that if you do so. When your phone's battery level is too low, then the charger of your phone supplies more power quickly to reach at the adequete level. This in terms produces more heat at the one end of the battery. However it would not leads to any explosion or fire but may harm your battery life which in turn leads to defective charging and explosions.
6. Avoid using your smartphone while it is charging: please try to avoid using your smartphone at some extent while it is charging. This is because during the charging, if you us your smartphone, the it causes the drag and drop of electric current of your battery. It is just like the water which is filling up a bucket with holes. Do this in terms produces excessive heat which damages your phone's battery life as well as leads to short circuit and explosion or fire. While this is not in a case of good companies smartphones like Samsung, Apple, windows, Motorola, xiaomi, etc, but it may happen with these companies too. So try to avoid at some extent. Also turn off the WiF, GPS, hotpot, Bluetooth, NFC, mobile data, if possibke during charging.
If you notice that your battery is swelling, then unplug your phone and remove the battery if it is user replaceable and buy an new one. Never attempt to dispose the battery by yourself. Always be wise and be safe.
Technologies have become an integral part of our live. If they use wisely then they can be proved as a best friend to us but if not then there will not a bigger nightmare than the explosion of your best friend in front of your eyes. So be safe and happy.
