The first issues have been traced back to the batteries manufactured by Samsung subsidiary Samsung SDI.
According to the company, the main issue with them was that “the negative electrode was deflected in the upper-right corner.” However, it says that an incorrectly located negative electrode tip was a factor too.
Samsung reacted to the initial wave of explosion reports by expanding production of Note 7s equipped with batteries made by Hong Kong firm Amperex Technology. However, these were also faulty.
“High welding burrs on the positive electrode resulted in the penetration of the insulation tape and separator which then caused direct contact between the positive tab with the negative electrode,” explained Samsung, which added that a number of Amperex Technology-made Note 7s were also missing insulation tape.
Samsung used three independent quality-control and supply chain analysis firms, UL, Exponent and TUV Rheinland, to conduct its investigation.
“For the last several months, together with independent industry expert organizations, we conducted thorough investigation to find cause to the Galaxy Note 7 incidents.” said DJ Koh, the president of the company’s mobile division.
“Today, more than ever, we are committed to earning the trust of our customers through innovation that redefines what is possible in safety, and as a gateway to unlimited possibilities and incredible new experiences.”
It is a moment of enormous significance for the technology giant, which will want to draw a line under the incident once and for all.
Samsung’s reputation has taken a battering over recent months, and it needs to produce an excellent new flagship in order to bounce back.
However, the highly anticipated Galaxy S8 will not launch at Mobile World Congress next month, as the company is carrying out extra safety checks to ensure it doesn’t go the same way as the Note 7
