At last, a conclusion to the fiasco that was the Samsung Galaxy Note 7
After months of thorough investigation following the global recall of the infamous Galaxy Note 7 smartphone last October, Samsung disclosed their findings on the reason why the device’s batteries kept on overheating and catching fire. It was mainly because of two different problems from the two different battery suppliers.
First was the batteries from their own Samsung SDI. There wasn’t enough room between the heat-sealed protective pouch surrounding the battery and other internal parts. Because of the thinness of the phone, tight quarters gave stress on the upper right corner of the battery. This caused the electrodes inside each battery to come into contact, leading to short circuiting causing the battery to explode.
Next was the batteries sourced from Amperex Technology Limited. Some battery cells were missing their insulation tapes and some batteries had sharp protrusions inside the cell that causes damage to the separator between the anode and cathode. Similar to the first incident, the battery separators were also thin which caused the short circuiting.
These reports were concluded after testing 200,000 devices and 30,000 batteries in a giant charging and recharging test facility built for the task. Samsung also stated “We are taking responsibility for our failure to identify the issues arising out of the battery design and manufacturing process prior to the launch of the Note 7”.
With this, we’ll just have to wait and see what Samsung will release on their next event early this year. Remember to hold off a little bit before buying new phones so it won’t cause you any inconvenience.
