Yesterday I showed a list of terminals that have been retired in the last or by bugs technical, or by the breach of the 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. It production in mass of million of models not avoids that some of them out with defects that in occasions, require of measures compelling from their creators not only for ensure it security of them users, but also, for ensure the survival of them own companies after it appearance of ones setbacks that can put in question the credibility of them same.
With the explosion of drums that have recently taken place in some models of Samsung, and that however, are not the first nor last show this problem arose in multitude of doubts about the risks and 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 starting, how works a battery?
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, power generation is very similar but in this case, we will focus on lithium to be the most widespread: imagine a box, at one end, there is an element called cathode filled with small positive electrical charges and in the opposite, another called anode containing other negative. Among them, we find a mass of this element which is directed toward the cathode to absorb power and then moved to the anode.
Why are the explosions produced?
The lithium can get to be unstable and react to a large number of elements. This generates the need of that in them batteries of our tablets and smartphones, exist several stripes separated between itself to avoid the mix of them loads electric of the anode and the cathode. When these “walls” not exist or have been manufactured of way defective, the different loads electric collide between them, what produces them overloads and in last instance, explosions 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 imitations, misconfiguration can lead to problems of this type. We can find an example in China, where explosions of devices which have lead to the death of their owners have taken place. During the manufacturing of the models, can filter is elements as dust, humidity 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 remember, before you talked of the existence of different cells chemical compound by a mix of sales within them batteries that is charge of not mix them cathodes and them 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? Have available more information related as e.g., them tests to which must submit is a device before exit to the sale so can know more about all them requirements that must meet a model until arrives to us.
The question of chemistry article. They can thus exploit the batteries of our tablets was published in TabletZona.
