In case, of the batteries sourced from Samsung SDI, there wasn’t enough room between the heat-sealed protective pouch around the battery and its internals. This is because the phone was so slim, tight quarters placed stressed on the upper right corner of each battery. In the worst scenarios, that caused the electrodes inside each battery to crimp and come into contact which leads to thermal runaway and short circuiting.

The mobile communication’s business president once said that Samsung hired 3 external firms just to solely investigate why the Galaxy Note 7 were catching fire. In addition to setting up its own laboratory to test 200,000 devices and 30,000 batteries. the created group for this project tested all aspects of the smartphone including its fast charging battery system, software, water resistance and its iris scanner as well. In case, of the battery sources from Amperex Technology Limited, some cells were missing insulation tape and some batteries had sharp protrusions inside the cells which led to damage to the separator between the anode and cathode.

These batteries also had thin separators which increased the risks of separator damage and short circuiting as well. The company offered this explanation at event that was organized in South Korea on Sunday. Samsung did not provide any details about its priority or quality-control procedures but the company says it has overhauled its safety testing process as a result of the investigations.
