Compressed battery design could be reason of Note 7 battery fiasco: Report

05 December 2016 0

Today, we have a new report from South Korea which suggests the reason behind Samsung’s Note 7 battery fiasco. The company’s aggressive design was behind the battery explosion which forces the South Korean giant to recall phablet and finally ending up the entire devices from the market.

The positive and negative layer was separated by a thin layer of polymer which makes sure both layers don’t meet. The heating of electrolytes was the reason of Note 7 explosions. As we can clearly see that in new design Samsung squeezed the battery that could be the reason both negative and positive meet and results in explosions.

Samsung also officially accepts that being too aggressive in Note 7 design could be one of the reasons of disaster. Another reason is slightly swelling of battery cell if the pressure exerted on it. This pressure is applied when a user’s handset is in the rear pocket and sitting on the chair could cause this pressure.


To make Galaxy Note 7 slim, Samsung reduces the battery cell size not only making it vertical but they also make it thin as well. Not just that Samsung also didn’t provide much space for compression problems that results in battery disaster. Samsung didn’t allow the third party to investigate battery problem but instead the company handled it themselves.

"The design and validation process for a new product is challenging for everyone. In this case, Samsung took a deliberate step towards danger, and their existing test infrastructure and design validation process failed them. They shipped a dangerous product. That this is possible at one of the top consumer electronic companies in the world is humbling -- and demonstrates the need for better tools. Instrumental is building them."-Instrumental


The Galaxy Note 7 total failure costs Samsung more than $5 billion and the brand name demolition is way more than that.
