Note 7 : an independent study puts into question the design “too … – The Digital

A battery too small

While the internal investigation of Samsung continues its journey to try to discover the cause of the explosions of the Galaxy Note 7, an independent research firm, has conducted his own tests and thinks to have discovered the reasons that led to the Note 7 to its loss.
While the twists and turns morbid the Galaxy Note 7 seemed to quiet down recently, engineers outside of Samsung come to explain to have found the cause of the explosion of the mobile before Samsung itself, which is still continuing its investigation. According to instrumental.I this is the design called “too aggressive”, which would have caused short circuits in the battery and thus causing explosions.

As some of us suspected, this would be the construction of the mobile that is at issue and not the battery directly. According to the study, the body of the Note 7 was too thin and too narrow to let the battery “breathe”. The engineers explain that the Li-ion batteries have a natural tendency to swell when the current passes through the different layers. In the case of the Note 7, the space for this swelling missing, the layers of positive and negative of the battery come into contact, which would lead to the famous explosions. Circumstances aggravated by the normal use of a smartphone that can sometimes be subject to slight twisting.

Security against innovation

What Instrumental.ai notes, is that in seeking the balance between security and exceeding limits, Samsung would have looked a little too much on the side of the second edge. The increase of the thickness of a battery is the simplest solution to increase capacity, the Korean company would have pushed the limits a little too far and would have disregarded the principle of leaving at least 0.5 mm of play between the battery and the hull. So far, Samsung had taken some safety measures by integrating the battery into a space that is isolated from other components, precisely to avoid the contacts. Brutal competition, therefore, would have had reason to Note 7. Wanting to make phones ever thinner than the competition with batteries always most important, Samsung would be a little too played with fire. And if safety tests have no doubt been made, the engineers seem to think that in the course of the changes in construction, all the different revisions would not have benefited from a test on the long-term enough. One more proof that the race for the finesse is probably not the axis most important development on smartphones today.
