Samsung has promised to deliver before the end of the year a clear explanation about Galaxy Note 7 of which the battery has a tendancy to overheat and ignite. In the meantime, the independent engineers also looked into this matter and communicate today their conclusions. They seem to confirm the first few tracks-namely, that the battery is not the only cause.
According to Instrumental.I, the battery can not physically enough breathing
We are facing a conjunction of elements : the battery has been rendered dangerous because of the design “aggressive” of the smartphone. By “aggressive”, it means “too late”. In this race to the finesse (the Note is only 7.9 mm thick, Samsung is perhaps going too far since the chassis would place pressure on the battery, as the compartment that receives the battery has been reduced to the maximum.
Thus, instead of having 0.5 mm of space to “breathe” in the battery, the battery of the Note should merely 0.1 and 0.3 mm of margin as shown in the photo above. However, in use, the battery has a tendency to somewhat swell up…
This pressure, as well as a physical divider anode/cathode end too have helped to promote the phenomenon of thermal runaway, which occurs when there is a short circuit between the cathode and the anode, and therefore a risk of fire.
The question now is whether this risk was not known from the design of the device. Samsung he wanted to go too fast to cut grass under the foot to Apple and its iPhone 7, at the risk of playing Russian roulette ? For the site Instrumental.have to the origin of this investigation, there was in any case not photo : “Samsung has clearly failed in its tests of validation of the design and delivered a dangerous product”.
