Even months later there's been no official report from Samsung on what caused the issues they were having with the Galaxy Note 7 batteries catching fire and exploding. However, a company by the name of Instrumental, which is a manufacturing tech company, has suggested that the reason for the very dangerous flaw was that there was no space allowed for swelling in the design of the battery. This suggestion has led some to consider whether or not safer standards and regulations on cell phones and battery designs need to be put into place.
Suspicious of the reported reason for the flaw, which was that there was an issue with one of the parts of the battery, Instrumental entirely deconstructed a Galaxy Note 7. In doing so, they were able to conclude that the phone’s rather aggressive design led to the battery explosions. As noted in a blog entry, Anna Shedletsky had this to say, “What we found was surprising: The design can compress the battery even during normal operation,” Shedletsky is Instrumental’s CEO, and founder.
