Galaxy Note 7 Owners Stop Using The Phone Immediately

[dlevere]

Lithium-ion batteries pack a lot of power into a small package. When these batteries overheat and burst, the results can be serious. This is why the U.S Consumer Product Safety Commission (CPSC) is urging all consumers who own a Samsung Galaxy Note7 to power them down and stop charging or using the device.

This consumer warning is based on recent reports involving lithium-ion batteries in certain Note7 devices that have resulted in fires. These incidents have occurred while charging and during normal use, which has led us to call for consumers to power down their Note7s.

CPSC and Samsung are working cooperatively to formally announce an official recall of the devices, as soon as possible. CPSC is working quickly to determine whether a replacement Galaxy Note7 is an acceptable remedy for Samsung or their phone carriers to provide to consumers.

We advise all consumers to report product safety incidents involving lithium-ion batteries in smartphones to us via www.SaferProducts.gov

It seems up until the past few years I'd never hear news of any kind of exploding batteries for anything. Is lithium-ion some new type of battery or has this just gone unreported in the past or something else??

Lithium-ion has been around commercially since at least the 90s. They've been getting used more and more in recent years for myriad reasons. It seems to be mostly the push toward smaller and smaller packages in a wider array of form factors that's causing this rash of fires. There's a flammable electrolyte under pressure in them, and in producing power they can produce a lot of heat and oxygen. Under normal operation, the battery can produce everything required for a fire without any outside help. So moving a few things around to get a smaller battery, or a custom built package that provides enough power for a new device can lead to difficulties. Even properly QAed batteries can turn out to have flaws.

A lithium-ion battery (sometimes Li-ion battery or LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

Lithium-ion batteries are common in home electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, tiny memory effect and low self-discharge. Beyond consumer electronics, LIBs are also growing in popularity for military, battery electric vehicle and aerospace applications. For example, lithium-ion batteries are becoming a common replacement for the lead acid batteries that have been used historically for golf carts and utility vehicles. Instead of heavy lead plates and acid electrolyte, the trend is to use lightweight lithium-ion battery packs that can provide the same voltage as lead-acid batteries, so no modification to the vehicle's drive system is required.

Chemistry, performance, cost and safety characteristics vary across LIB types. Handheld electronics mostly use LIBs based on lithium cobalt oxide (LiCoO2), which offers high energy density, but presents safety risks, especially when damaged. Lithium iron phosphate (LiFePO4), lithium ion manganese oxide battery (LiMn2O4, Li2MnO3, or LMO) and lithium nickel manganese cobalt oxide (LiNiMnCoO2 or NMC) offer lower energy density, but longer lives and inherent safety. Such batteries are widely used for electric tools, medical equipment and other roles. NMC in particular is a leading contender for automotive applications. Lithium nickel cobalt aluminum oxide (LiNiCoAlO2 or NCA) and lithium titanate (Li4Ti5O12 or LTO) are specialty designs aimed at particular niche roles. The new lithium sulfur batteries promise the highest performance-to-weight ratio.

Lithium-ion batteries can be dangerous under some conditions and can pose a safety hazard since they, unlike other rechargeable batteries, contain a flammable electrolyte and are kept pressurized. Because of this, the testing standards for these batteries are more stringent than those for acid-electrolyte batteries, requiring both a broader range of test conditions and additional battery-specific tests.

This is in response to reported accidents and failures, and there have been battery-related recalls by some companies.

Samsung says it knows why the Galaxy Note 7 exploded — and it's no surprise

I think I got hit by captain obvious so hard I forgot I was guessing without evidence. All they said was "Obviously it was the battery that caused the fire." I thought we already knew that the entire time, but I guess not.

The battery is supposed to be packed so tight that some parts might be touching that should never touch. Any pressure on the phone could cause them to rub together. That's probably why the batteries are faulty. They were testing out new batteries.

Verizon to redirect calls made from dangerous Galaxy Note 7 phones

Non-emergency calls from Note 7 will be redirected to Verizon customer service.

It could have been the airbag supplied in the back of the phones, you never know.
