The South Korean tech giant Samsung has asked consumers to hold off the Galaxy Note 7 and suspended the sale and replacing the cell, after a series of incidents with new batteries.
RELAPSE. In September, the house had attracted 2.5 million smartphones this model following a number of reported incidents of explosions, later clarifying that the new data devices in place were safe. But some new
events have necessitated a more drastic decision, waiting for it to clarify the causes of the malfunction.
A man in Kentucky has woken up in a smoke-filled room, from the cell just replaced. A flight to the United States has been evacuated for the same reason, while in a couple of episodes, Minnesota and Hawaii, the devices have exploded in the hands of two users.
WHAT CAUSES EXPLOSION? It is precisely the point that the company's investigation will clear up. In some cases, especially before replacement of September, the episodes are due to overheating, a risk that is well specified in the notices of the millions of cell phones with lithium batteries sold all over the world.
But in other circumstances outside temperatures or due to long use are not concerned. Origin there may be a short circuit caused by contact between positive and negative electrodes in a defective batch of batteries (Samsung has several suppliers located in various parts of the world).
BRAKELESS. Always a manufacturing defect could make some batteries prone to charge too much, not that they stop doing it once loaded. This could cause the formation of bubbles of oxygen, highly reactive with the lithium battery. Defective batteries may become excessively discharged, without dying out like the normal ones, and this behavior may cause the reported incidents.
The willingness to resort to ever more compact batteries and light, efficient and able to recharge quickly, could have played a role in the story, whose real engine may be a flaw in the quality of the components control systems.
