Yesterday I showed a list of terminals that have been withdrawn in the past by technical failures, or for breach of expectations that their manufacturers deposited in them. In electronic of consumption, the errors are something that despite not affect to amounts significant of devices, is happen with enough frequency. The mass production of millions of models does not prevent some of them come with defects that sometimes require decisive action by its creators, not only to ensure the safety of users, but also to ensure the survival of the companies themselves after the emergence of a few setbacks that may call into question the credibility of the same.
With them blasts of battery that have had place in some models of Samsung recently, and that however, not have been them first or last in show this problem, have emerged crowd of doubts about the risks and the causes of these errors. All companies have had incidents related to this component and in the majority of cases, the chemistry is the cause and also the solution. Why is cause the leak? What processes are in the interior of tablets and smartphones so is produce? Now you have more about them and also you give a series of small tips to prevent them.
Before you begin, how does a battery work?
A few months ago we made a brief review on different batteries that can be found in our devices and the materials used for its manufacture. In all them, the generation of energy is very similar but in this case, us will focus in them of lithium to the be the more extended: imagine a box, in one of them ends there is an element called cathode full of small loads electrical positive and in the opposite, another called anode that contains others negative. Among them, found a mass of this element that is directed towards the cathode to absorb power and then, is moved to the anode.
Why is produce the explosions?
Lithium may be unstable and react to a large number of elements. This generates the need for the batteries of our tablets and smartphones, several stripes separated to prevent mixing of the electrical charges of the anode and cathode. When these “walls” do not exist or have been manufactured in a defective manner, different electric charges collide, causing overloads and ultimately, explosion or even fire.
The role of the operating system
In addition to the failures of manufacture of the component itself, the rest of the device can also cause battery problems. Own softwares have a number of functions that are responsible for controlling the flow of electric current that is transferred to the terminal and the time required to perform a full charge. In the case of the imitations, a bad configuration can lead to problems of this type. A example it can find in China, where have had place explosions of devices that have arrived to cause the death of their owners. During the manufacture of models, they can be filtered elements such as dust, moisture or small pieces of metal that also increase the risk.
The role of the users
While current smartphones and tablets are more resilient to that which we found few years ago, must not forget that they are not evergreen. The bumps, scratches and the subjection to extreme weather conditions, quickly shorten its useful life. If you remember, before I talked of the existence of different chemical cells composed of a mixture of salts inside the batteries who took care not to mix the cathodes and anodes. With them hits and others impacts of way frequent, the separation between them is eliminated.
While Samsung has staged news portals and news from around the world for problems with Galaxy Note 7, the reality is very different, since it is believed that of every million tablets or smartphones that are produced, less than a thousand ends up being victim of explosions. In addition, there is a kind of unwritten rule that says higher is the terminal or his family, less risk there is of that cause such problems since they undergo more rigorous controls of quality. On the other hand, we find the tests made by regulators in regions as Europe, which are also responsible for reporting these bugs early way, therefore, would be an exaggeration think that most users are at risk by the fire of their terminals.
After learning more about the causes that are behind one of the most important accidents that can occur to tablets and smartphones, do you think that they should be more harden tests that must pass before reaching the market? Do you think that these setbacks are something specific? You have available more information as for example, the tests that should be a device before going on sale so you can learn more about all the requirements a model until you reach us.
The question of chemistry article. They can thus exploit the batteries of our tablets was published in TabletZona.
