Samsung Galaxy Note 7 explosions reportedly caused due to 'aggressive battery design'

Samsung allegedly knew of the dangers of the Galaxy Note 7 battery design, but still went ahead with it.

Samsung is currently believed to be investigating what caused the Galaxy Note 7 battery to explode, and is set to come out with an official statement before the end of this month. Before that however, an independent team of hardware engineers cracked open a Galaxy Note 7 and claims that Samsung’s aggressive design for the battery might be the culprit behind the massive fiasco.


In order to keep the Galaxy Note 7 really slim, Samsung is said to have employed a super aggressive design, and this meant that the battery was continually being compressed, Instrumental reports. The engineers say that Samsung used a pair of polymer layers drenched in electrolytes to separate positive and negative layers. But the compressing of the battery forced the positive and negative layers to squeeze and eventually come in contact with each other. This led to the battery heating up and causing an explosion.

Interestingly, the US Consumer Product Safety Commission too came to the same conclusion after an initial investigation earlier this year. An official was quoted as saying that the real reason for the batteries exploding is that the “phone’s battery was slightly too big for its compartment and the tight space pinched the battery, causing a short circuit.”

But what could be potentially another blow to Samsung is that the engineers at Instrumental claim that the company already knew about the dangers. Samsung‘s engineers apparently knew about the risks of the highly compressed battery design they were employing, but still “took a deliberate step towards danger.”

The Galaxy Note 7 is one of the biggest tech fails this year, and the discussions will continue until Samsung comes out with an official statement. Before the recall, Samsung had claimed that over 2.5 million Galaxy Note 7 units were shipped. But after reports of explosions, the company announced a worldwide recall, even delayed its launch in India, and ultimately pulled the plug. Later, several public transport services banned passengers from carrying the phablet. At the peak of criticism thrown towards the company, Samsung Mobile’s chief Dong-Jin Koh aka DJ Koh made a heartfelt apology and vowed to “restore trust of consumers.” RELATED: Samsung apologizes for Galaxy Note 7 battery fiasco via full-page newspaper ads
