Every once in a while the news of a mobile phone explodes, and the fact is that the battery of your smartphone is indeed like a small pump made up of liquid electrolytes … Still, you should not worry too much if you take good care of it!
Of explosions in their smarthones None of the most important manufacturers in the industry has been spared, neither Apple with its iPhone nor Samsung with the incendiary Galaxy Note7, or even Chinese mobiles as popular as this Realme that recently exploded in India by opening a dispute between user and manufacturer they blame each other for the problem.
It is not for less, because certainly it is not easy for a mobile phone battery to explode without manipulating or mistreating it, although we must recognize that it can indeed explode because in essence it is a small bomb that you carry with you most of the day, and which is made up of highly flammable and reactive liquid electrolytes.
Be that as it may, you should not be alarmed yet, because as we have already commented it is not that they explode frequently but rather the opposite, in normally isolated cases that refer to manufacturing problems, improper handling or misuse caused by excessive temperatures or charging with an unsupported transformer.
We will try to explain that yes, what reasons can cause an explosion and what you should do to take better care of your batteries and avoid you a morrocotudo problem by fire or explosion. Do you want to learn something useful today? Follow us …!
The battery of your smartphone can explode due to its nature, but most of the time it will if you do not use it correctly or if it arrives with a manufacturing defect that we will help you identify

What is a rechargeable lithium battery? What is it made of?
Basically a battery is a component that stores energy by reacting chemical elements with each other, but in its design the stability of the components and the control of the flow of electrons through conductive materials are always ensured to avoid any problem.
In any case, these problems may exist, because many are the elements of a battery and there are many possible points of failure that even we can induce ourselves. The main components of a lithium battery are as follows:
- Anode.- It is the negative pole of the battery and from it the electrons leave the cathode.
- Cathode.- It is the positive pole of the battery and receives the electrons that come out of the anode.
- Electrolyte.- It is an organic liquid in which the anode, the cathode and the separator between them are submerged, acting as a conduction enhancer for the electrons to move. It is extremely flammable.
In addition, the batteries also incorporate sensors that help you avoid problems from overvoltage or overheating, and to monitor the stability of all components.
The process by which electrons flow from the anode to the cathode is called redox, or reduction-oxidation, and it is a reversible process that gives rise to the popular cycles that are talked about when we mention the useful life of a lithium battery. Materials lose properties and the oxidation capacity or loss of electrons loses strength over time.
Risk is minimal given the nature and design of any battery, but nobody is free from sin and sometimes there are manufacturing problems, improper manipulations to try to fix the phone or replace the battery at home, other causes such as excessive heat or even the use of an unsupported charger. You will have to be careful …
This is how your mobile battery works
The most common batteries that we use in our smartphones are made with lithium ion technology, thus using a metal that favors the transfer of electrons and is also light.
In this type of batteries we will generally have the following materials: lithium and cobalt oxide at the cathode, graphite at the anode and a kind of lithium salt with alkyl carbonates in the electrolyte completing the set.
The most dangerous material is as we have discussed the electrolyte, since lithium is a highly reactive alkali metal even in contact with air, in addition to being flammable and which can boil with excess temperatures.
Problems come when lithium mixes with dimethylcarbonate, producing a term leak that usually ends in spontaneous combustion. It is a chain reaction, where a part of the battery heats up infecting the rest and exploding or catching fire definitively and irremediably.
In addition to overheating, cobalt oxide can release oxygen, and this gas reacts with the electrolyte in a direct way, decomposing and generating a carbon dioxide that you will need to go out blowing up the camera in which it is in electrolyte that will catch fire immediately.
All this can also happen by overcharges, overheating, physical damage to the battery itself, or faulty designs they can cause internal shorts, so It is not a common problem, but it can occur perfectly in isolated cases given the enormous number of mobile phones that are sold worldwide.
How to take care of the battery to avoid unnecessary scares
Already known how the batteries of our current mobiles work, it is good to know how to take care of it to avoid problems and possible bloats, fires or explosions, so let’s review …
Never tamper with your mobile phone if you are not an expert in the matter, why try to remove the battery in devices unibody they are not ready for it could lead you to break the plastic protections of the battery causing the electrolyte to come into contact with the air and can ignite spontaneously.
Also, if your battery has a manufacturing failure – rare thing but that can happen – surely you will detect it by some strange swelling in the rear, bulging or even excessive temperatures and malfunctions, like sudden restarts. In this case, you should contact the technical service so that they can replace it as soon as possible.
Not only that, and it is also ideal avoid high temperatures and battery overheatingBecause you will lose efficiency much earlier and high temperatures can make plastics lose their insulating properties or cause combustion in the electrolyte.
These overheats are usually controlled by the smartphone itself, which will turn off if it detects excessive temperatures, but just in case never leave it sitting for a long time on a table in the sun, and do not use non-recommended chargers by the manufacturer or with much higher powers, because you could charge the battery.
As you may have seen, they are some simple guidelines that anyone can perfectly comply with a tad of care, so you no longer have an excuse in this avoid being to blame for spontaneous combustion of your mobiles. What do you think, have you ever had problems with your batteries?
