Earlier this week(22^nd January 2017) the tech giant Samsung officially announced  the results of its Galaxy Note 7  fire investigations. Since the recall of the device last September and October, respectively. And like most expectations, the battery was to be blamed. Samsung compiled 200,000 phones and 30,000 separate batteries, employing 700 people purposely for the cause and found that neither the phone’s fast charging feature nor its waterproofing, had any connection to the explosions.

As reports stated last week the batteries built by Samsung SDI, referred as Battery A, had a defect at the top right of the lithium ion grouping, and in some cells, caused fire through repeated charge and discharge. The batteries from Amperex, the Hong Kong-based facility that built the second group of batteries of the Note 7s, referred to as Battery B,  had a defect in the top left portion of the cell that caused short circuits in a small number of units. In addition, Samsung says some of these batteries didn’t have the necessary insulation to protect overheating from spreading to the rest of the battery in a short circuit scenario.

Through the investigation, Samsung worked with a number of independent organizations, including UL, Exponent, and TUV Rheinland, to build an eight-step battery safety check that will be implemented throughout the company’s manufacturing processes in the future in order to prevent any such problems from happening again.
