Did The Quest For A Thinner Phone Cause Samsung Fires?

Tuesday, December 13th, 2016 by | Filed Under: Android, Quick Tips, Smartphones

The engineering company Instrumental has been looking into the cause of those exploding Galaxy Note 7 batteries. Samsung’s flagship device was recalled after a series of fires caused by the batteries overheating and exploding.  Their conclusions are pretty interesting.


You’ll remember that Samsung originally said the issue was caused by a manufacturing defect in batteries and then offered replacement batteries. But then those batteries started going up in flames as well.  Instrumental got their hands on a Note 7 and took it apart to see if they could figure out what was causing the problem.

They think the root of the problem is the quest for an ultra-thin device. The device is actually so thin that it continually compresses the battery.  These devices use a super think lithium polymer battery with negative and positive layers that have separator layers between them. If the separator layers are compromised by the pressure and the positive and negative layers touch… boom goes the battery.  The reason those separator layers were so thin was Samsung’s desire to an ultra-thin device. These engineers think that the quest for thinner and thinner devices could lead to more and more battery issues in the future.
