Galaxy Note 7 fires likely caused by 'super-aggressive manufacturing process' | ZDNet

Manufacturing engineering company Instrumental has carried out a teardown of the Samsung Galaxy Note 7, and it believes it has found the cause of the battery fires and explosions.

According to Instrumental, the problem came down to a "super-aggressive manufacturing process."

In a nutshell, here's the problem:

  • Manufacturers want to make their devices as thin as possible
  • That means making the batteries thinner
  • The thinner a lithium-ion battery, the less electrolytic separator there is keeping the lithium cobalt oxide anode from coming into contact with the graphite cathode
  • Physical stress, either from being in a pocket or from heat build up (either environmental or from charging), can deform the battery, potentially causing the anode and cathode to come into contact
  • If the anode and cathode come together, then you have problems (in the form of fires and potential explosions)
"Samsung engineers designed out all of the margin in the thickness of the battery, which is the direction where you get the most capacity gain for each unit of volume," wrote Anna Shedletsky, CEO and founder of Instrumental.

Another potential problem with Samsung's design is that the battery hasn't been given much room to expand. Some of the tolerances between the battery and the roughly CNC-machined aluminum chassis are as small as 0.1mm. During the charging process a battery expands, and because of the tight tolerances it is possible for the battery to be punctured, again potentially resulting in fires and explosions.

"In this case, Samsung took a deliberate step towards danger," wrote Shedletsky, "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."

Hope they bring back removable batteries. Don't really give a fukk a bout how slim it can get, I usually bought extended batteries anyway.

I'm not sure about this...

It makes total sense that this could be the issue but if it was a design issue the failure rate should be a lot higher than 100 phones out of 2 million...A design issue implies every phone produced has the flaw...

Mine is still good btw...:yeshrug:

It has to be way more than 100. if it was such a low number it will still be on the market.

There are many ways to spin numbers. No company is going to do such a massive recall on such small numbers in incidents.

Spin what?

Those numbers are government numbers straight from the CPSC bruh...The link I gave you is a .gov, it's not some fugazee android site...

When there are reports of injuries and property being destroyed products get recalled...You don't need 1000 people to get hurt and it's not like Samsung had a choice here, the products reputation was severely damaged by the media having everyone think its an IED...There were 1.9 million units sold in the US between both recalls with only 96 reported failures and its fair to question how many of them were legit...

How many times did you see that burned jeep in the news? Over a dozen?

That infamous jeep incident where everyone blamed the phone before the fire department got a chance to look at the damn car...The fire departments investigation concluded a month later and there was no link to the Note 7 being the cause of the fire...

Finally, a bit of good news for Samsung. St. Petersburg Fire Rescue have today announced that they were unable to determine whether a faulty Galaxy Note 7 left plugged into the cigarette lighter socket of a 2005 Jeep Grand Cherokee was the exact cause of the fire that destroyed the vehicle.

The owner of the Jeep, Nathan Dornacher, blamed the handset for sparking the fire right from the word go. However, St. Petersburg Fire Rescue has listed “undetermined” as the official classification for the fire that occurred at 3257 58th Street N on Monday, September 5.

“Due to the destructive nature of the fire, and multiple possibilities that could not be eliminated as to the ignition source, this classification was determined most appropriate,” writes a fire investigator on behalf St. Petersburg Fire Rescue in his official report on the matter.

While it’s still possible that the Galaxy Note 7 was to blame for the car catching fire, the investigators were unable to discover a clear link. It’s not uncommon for car batteries to swell in hot weather, though, so I believe that a minor fire caused by the handset may have ignited the battery, leading to the full-scale explosion we saw in the images.

It's to late...I've been rocking this LG V20 and come to the realization it's the GOAT phone...

Samsung lost me as a TV customer...now they losing me as a phone customer...

im an iphone guy and the note 7 impressed me, a lot. had to deal with a lot of returns for these.

i read (cant remember where) that all of the future flagship samsung phones will have the edge, starting with the s8 of course...i expect that phone to release in about 2-3 months. they gotta get it out quick to regain customers.

I had no idea the Note 7 was fire until after it blew up. 5"7 AMOLED screen, with a smaller body than the iPhone 7 Plus. More ram, fast and wireless charging, and sd card slot :wow:The gif creator with the s-pen was the icing on the cake. Man this was the perfect phone for Kodi. Samsung fukked up bad.
