At the end of this month we will know from Samsung the real reason for the whole problem of the battery that the Galaxy Note 7 had and that caused many models to catch fire to the amazement and surprise of the user. A very serious problem for the company that will take time to remove from your record as it is a big stain on your resume.
Some of the reasons that have been given become more relevant and have their logic, such as the one in which the exit points were too close to each other, which allowed the loading and unloading sources to come together and caused the fire. end of device. An instrumental design engineering firm, has decided have a look to check what really happened.
In the breakdown and analysis of a unit, the team of Anna-Katrina Shedletsky, founder and CEO of the firm, found that handling the Galaxy Note 7 in a normal way, got the phone to expand and reduce on the battery. This put pressure on the positive and negative layer of the cell. When those layers are in close proximity, the protection is of little use, and the layers begin to feed back energy into each other, and the temperature starts to rise so that the explosion finally originates.
Indeed, Samsung choosing to fit a 3.500 mAh battery in a very small space amplified the potential impact, although this is where the real debate lies. Battery tests they need a time of a year for some tests and thousands of them need to be tested to get meaningful results. It is possible that the innovative battery manufacturing process was changed in the middle of development, and newer versions of the batteries were not tested as rigorously as the first samples.
The tolerance designed for the battery slot or space, at some points they did not even reach 0,1 millimeters, which does not help. There was no room for the Z-axis to "breathe," when there is usually at least a 10% tolerance.
