Samsung's decision to halt sales of the new Galaxy Note 7 because of
reports of battery explosions is an extraordinary step for a tech giant
to take.

The firm said it had identified a battery issue but did not elaborate.

But if a lithium-ion battery cell charges too quickly or a tiny
manufacturing error slips through the net it can result in a short
circuit - which can lead to fire.

One expert urged the industry to find safer alternatives to lithium.

"I think one should be concerned and push towards safer battery tech,"
said energy storage expert Professor Clare Grey from Cambridge University.

"That should be an important focus on research and industry development.

"While most manufacturing flaws will be picked up during initial
testing, it's not an infallible process."

However Prof Grey also said that people should not panic.

"I'm standing at an airport - every single person would have to stop
what they are doing if we took their batteries away from them," she said.

"We all take risks in our lives - we drive cars sitting on top of
flammable organic liquids. Other tech is coming along that is safer."
Common causes

There have only been 35 cases of the Galaxy Note 7 catching fire
reported worldwide following 2.5 million sales, Samsung says.

The lithium ion batteries used by Samsung are common across the tech
industry - so what makes them hazardous?

It's important to understand a little about how they work. Simply they
contain a cathode, an anode and lithium.

The cathode and anode are separated by an organic liquid called an
electrolyte and a porous material called the separator.

The lithium travels through the separator, within the liquid, between
the two.
Quick charge

If the battery charges too fast, generating heat, lithium plates form
around the anode which can create a short circuit.

"Normally you would have a battery management system that controls the
rate at which you charge," said Prof Grey.

"Batteries are optimised so that you don't charge too fast - if you do
that you will plate the lithium."

This is also why battery charging can be a frustratingly slow
experience, she added.

Other faults that can cause a short circuit include contamination by
tiny fragments of metal during the production process or minute holes in
the sealing, which might not become apparent until the battery has been
charged a few times as the materials expand and contract.

"The manufacturing has got a lot more standardised than it was 10 to 15
years ago," said Prof Grey.

However battery packs - combining battery cells to generate more power -
can be problematic and this is increasingly common. Batteries containing
12 cells, for example, are readily available for laptops.

"The more you put together, the higher the likelihood that some will
fail," she added.

"There are still flaws emerging but it's getting better. It is a
challenge - with so many being produced, you just need one error."
Signs to watch out for

There can be symptoms indicating that a battery is about to fail, said
support and repairs provider Geek Squad.

"Sometimes, a battery will start to swell and bulge before it fails
completely, as the internal cells rupture and break," it says on its
website.

"But the bulge doesn't always happen. If not, you might notice that your
device is a little warmer than usual - but let's be honest, our phones
get fairly warm during standard usage anyway."

The firm suggests disposing of any batteries displaying these signs.

Exactly how through ignorance do you drain a cell phone battery that's
in the cell phone too fast and cause it to explode? From what I've
seen of the reports, the Samsung were exploding while being charged.
Same thing with those hoverboards, some of them have burned houses
down. Boeing had the 787s grounded right after introduction because
their Lion batteries were catching fire. AFAIK, all of them were
when they were being used normally, usually while charging not
discharging. In the case of Boeing, after all the analysis, they
still couldn't figure out what the root cause was. So, they just
put better containment around them. Doesn't make me too comfortable.
There are some things where saving some weight just isn't worth it.

Lithium batteries explode when you put too many electrons in them and not enough battery cooties in there to eat excess electrons. A properly designed lithium ion battery has a cootie door much like a tiny pet door to allow battery cooties to enter and leave as needed. The battery cooties poop protons but they must do it outside the battery so the battery isn't contaminated with battery cootie poop. The battery must not be in an unventilated container or space. It must be vented so the battery cooties can escape when the battery is dead so the swarm can find another battery. Battery cooties can lay dormant for many years waiting on a new battery if they must. If you use a high power optical microscope over the vent on a lithium ion battery, you may be able to see the larger battery cooties especially the pregnant queen battery cootie. An electron microscope is not recommended unless you are looking at dead battery cooties because the live battery cooties are attracted to the electron beam and will cover the electron microscope and try to mate with it. Anyway, that's why lithium ion batteries explode. ^_^

Who says these Lion batteries he's talking about are exploding becaue
the consumers drained them too fast? How does a consumer with a cell
phone drain it too fast? Never seen a cell phone yet where it's sold
and spec'd saying it can only be used X mins continuously or it will
blow up. Just playing your silly game here, because of all the Lion
batteries that I've seen in the news that blew up, I haven't seen one
where it was attributed to draining it too fast. Most of them were
when they were being *charged*.

Sure, if you're dumb enough to do that and it's charged. But again,
that isn't the problem, that isn't what's happening with any of these

are burning up, exploding in normal use.

Samsung said it thought the problem came from a €œminute flaw€� in the

battery was coiled incorrectly, causing more stress.

With a note that Li-ion/pol cell chemistry
( one of many cell chemistries based on lithium )
at normal circumstances does not contain free metallic lithium.

The neutral lithium atoms are intercalated
within the honeycomb plates of graphite electrode.

Only in case the cell is overcharged, the metallic lithium
eventually starts to deposit on the anode graphite surface.

Reaction rates of undesired exothermic side reactions increases,
involving namely with metal oxides of cathode
eventually the LiPF6 electrolytes
and organic carbonates R-O-CO-O-R'.

The carbonates are flameable liquid and combined with the lithium
cam make a hell from such damaged battery.

a notebook battery intentionally brought to critical damage point
can cause up to 2 m high violet and violent flame.

Sure, if you're dumb enough to do that and it's charged. But
again, that isn't the problem, that isn't what's happening with
any of these problem Lion batteries, it's not what's happening
with Samsung. They are burning up, exploding in normal use.

It's likely due to problems with the manufacturing process and/or
defective components within. The batteries can fail in fantastic ways
by being charged, discharged or just sitting idle, if the right
combination of internal failure takes place. Mostly, it's the
seperator that runs into problems. When it fails due to holes being
poked thru it by inferior construction materials that are uber tiny
in nature, your battery is literally, internally, shorting out. If
the organic solvent that's being used for electrolyte for some reason
damages/degrades the seperator, you've got yourself an internal short
circuit condition that can affect one or more cells.

As other cells are forced to join in, either by being shorted
themselves or just being heated by a failing cell near them, thermal
runaway begins to take hold. The organic solvent being used as an
electrolyte is turning into a gas due to the heat. A cell that's now
causing excessive heat can ignite it, inside the battery pack. If
that happens, you have a cascading thermal runaway issue and the
battery pack will go up in flames.

That's actually a rare event if you consider how many batteries of
this kind are made and used every day. Most of the time, the
batteries internal and external safeties will kick in and prevent the
fire aspect, although the battery is still going to be permaruined as
a result of the safety being enabled. It's a one shot deal.

Defective charging circuitry either in the charger and/or the battery
pack. It can also be a problem with the seperator or some impurity in
the organic solvent that pokes one or more holes in the seperator.

It's causing the organic solvent electrolyte to get too hot and turn
into a gas. As it does so, any cells that are hot enough can ignite
it, inside the battery pack. If/when that happens, other cells will
be forced to join in cascading thermal runaway effect. Result:
battery pack catches fire and burns.

container or space. It must be vented so the battery cooties can escape when the battery is dead so the swarm can find another battery. Battery cooties can lay dormant for many years waiting on a new battery if they must. If you use a high power optical microscope over the vent on a lithium ion battery, you may be able to see the larger battery cooties especially the pregnant queen battery cootie. An electron microscope is not recommended unless you
are looking at dead battery cooties because the live battery cooties are attracted to the electron beam and will cover the electron microscope and try to mate with it. Anyway, that's why lithium ion batteries explode. ^_^

Samsung's decision to halt sales of the new Galaxy Note 7 because of
reports of battery explosions is an extraordinary step for a tech giant
to take.

The firm said it had identified a battery issue but did not elaborate.

But if a lithium-ion battery cell charges too quickly or a tiny
manufacturing error slips through the net it can result in a short
circuit - which can lead to fire.

One expert urged the industry to find safer alternatives to lithium.

"I think one should be concerned and push towards safer battery tech,"
said energy storage expert Professor Clare Grey from Cambridge University.

"That should be an important focus on research and industry development.

"While most manufacturing flaws will be picked up during initial
testing, it's not an infallible process."

However Prof Grey also said that people should not panic.

"I'm standing at an airport - every single person would have to stop
what they are doing if we took their batteries away from them," she said.

"We all take risks in our lives - we drive cars sitting on top of
flammable organic liquids. Other tech is coming along that is safer."
Common causes

There have only been 35 cases of the Galaxy Note 7 catching fire
reported worldwide following 2.5 million sales, Samsung says.

35 / 2.5 million = very small number.

When I was a teen in the 1970s, my uncle in law was in charge of the
battery yard for the (seven) submarines of the Greek Navy. He would have
nightmares of the batteries exploding. Specifically, it was hydrogen buildup
which was most explosive. Batteries are stored energy, which is why they
explode. I can't believe how naive folks can be thinking that you can store
ANY energy and NOT have the possibility of an explosion. TNT and rocket fuel
is based on nitrogen triple bonds which are the most potent known fuel
source.

Let summarize the major mistakes :

1/ Lithium batteries operations are related to building up hydrogen.

Li-ion/pol cells do NOT use chemistry, building up hydrogen,
as they use lithium hexafluorophosphates dissolved in
dialkylcarbonates as an aprotic electrolyte.


2/ Batteries are stored energy, which is why they explode.

Coal is much more concentrated energy than Li-ion cells,
but does not explode. So stored energy itself
is not cause of explosion. There is needed a mechanism
releasing it by uncontrolled way, like punctures
and overheating out of operational conditions.

Human body stores energy as fat, again with much higher
specific energy content than Lithium cells,
but explodes neither.

3/ TNT and rocket fuel is based on nitrogen triple bonds which are the
most potent known fuel source.

Nitrogen triple bond in the gaseous nitrogen or cyanides
is one of the strongest chemical bonds ever and you need
to PROVIDE a lot of energy to break it.

BTW, neither TNT nor rocket fuels DO NOT contain nitrogen
bonded by triple bonds.

So, be careful with the naive tag...

These would be lead acid batteries, where yes, hydrogen build up was a
problem.

Well, some people acumulating energy in form of beans really explode..

Yes and no. They are stored energy as opposed to creating it on the
fly, but, that's not why they can 'explode' - The act of storing energy
itself doesn't automagically make it an explosive. And, not all
batteries actually go boom when a catastrophic failure does occur,
either. Some will vent/leak and do nothing else. Others experience
drastic temperature increases and a fire begins, occasionally followed
up with an explosion. Sometimes, not.

It's not correct on the face of it to say that batteries explode
because they store energy. There's more to it than that.

I can't believe how naive folks can be thinking that you can store
ANY energy and NOT have the possibility of an explosion.

It still doesn't surprise me to see people posting... at best, ill

Here's an example of a car battery that won't explode.

Like a D-cell for your flashlight, you "throw it away"
at your destination.

*That's* how you get a vehicle which has only
an electric motor, half way across the country.
I haven't seen a price listed for the aluminum,
to see just how uncompetitive it is.
