Samsung Explains Why the Galaxy Note 7 Kept Exploding

     

                                              Samsung has released its official report on why the batteries in the Galaxy Note 7 smartphone were exploding. Notably, the issues differed between the original battery and the replacement battery used after the first recall.

“For the last several months, together with independent industry expert organizations, we conducted thorough investigation to find cause to the Galaxy Note7 incidents,” DJ Koh, President of Mobile Communications Business said. “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.”

Based on what the company learned from the investigation, Samsung implemented a broad range of internal quality and safety processes to further enhance product safety including additional protocols such as the multi-layer safety measures and 8-Point Battery Safety Check. Samsung also formed a Battery Advisory Group of external advisers, academic and research experts to ensure it maintains a clear and objective perspective on battery safety and innovation. 

Here are some of the main issues uncovered by the investigation:

Root Cause: Manufacturer A

Based on the results of analysis and testing, the most likely root cause for the thermal failure of certain Manufacturer A cells was determined to be unintended damage to the negative electrode windings consistently in the corner of the cell closest to the negative tab

Root Cause: Manufacturer B

Based on the results of analysis and testing, the most likely root cause for the thermal failure of Manufacturer B cells was determined to be internal cell faulting between positive electrode tab welding defects and the copper foil of the negative electrode directly opposite the defective welds
