If you’ve been following the recent news of TudoCelular, must know that thousands of units of Galaxy Note 7 are in recall process due to a series of explosions (1, 2) documented while devices were being loaded with the last occurrence happening a few hours ago in Australia, giving a loss of more than R $ 4,000 to the laptop owner.
the batteries in question, manufactured by subsidiary Samsung SDI, apparently bring a “rare defect” manufacturing that after investigation, was finally unveiled by the south Korean firm
in an official statement, Samsung said:. “based on our research we found that there was a problem with the battery cell. Overheating of this occurred when the anode-cathode contacted, an error that is very rare in the manufacturing process. “
For more that smartphones have evolved considerably in recent years, battery modules failed to keep all this progress, still depending on highly flammable chemicals such as, lithium, which also has a high electrochemical potential.
When a defective battery overheats, your cells break down, triggering a chain reaction, something called “thermal runaway”, one of the main reasons for which it explodes. The problem may be triggered by a short circuit simple or, as in this case, a manufacturing defect.
The situation involving the phablet is so critical that even the organ responsible for the regulation of flight and safety passengers in the United States is considering banning the Galaxy Note 7 to board the aircraft.
