LG video threatening fines and jail time for consumers using their cells

Also, even at 275Wh/kg of energy density, current top of the line lithium-ion cells are nothing compared to hand grenades.

That means a kilogram of lithium-ion cells can deliver a total of 990kJ/kg, while TNT can deliver a total of 4000kJ/kg.

And as djozz said, you are limited by the internal resistance of lithium ion cells during a complete short, and the fact that they can’t actually detonate as such.

The main purpose of the friendly and basically helpfully informative video is to let the masses know what the dangers of unprotected Li-ion cells are, and that protected cells are the safer option for those who are not experienced.

I don't think I will go to jail if my neighbors dog ambush charge attacks me, and I throw an unprotected cylindrical lithium-ion cell at it.

Anything can be dangerous. I remember a local lady died like 5-7 years back by drinking too much water, for a contest, and died. We didn’t ban waterfaucet when that happened.

Perhaps we should! Every single person who drinks water eventually dies. Think of the children!

Is that why the “exploding flashlight” stories happen, because the energy released is confined in a tube until pressure builds up?
Let’s hope nobody puts a bundle of li-ions in a pressure cooker ….

Yeah, I realize there’s a chicken-little problem here.
The point of that old IEEE article was the rate of change in energy density — back then it was going up fast. Now? I dunno.

I have no idea what she is saying, but she’s hot. Good enough for a thumbs-up on the video!

Most of the general public should not own or use bare li-ion cells.

They closely rememble an alkaline battery and the general public has used alkaline batteries (or NiCD, NiMH etc) in a flippant and careless manner their entire life. They do not take any special precautions.

So when they see an 18650, to their untrained eyes it’s just a bigger version of what they are familiar with. Inevitably they use them flippantly and without caution.

There are members of BLF who should be be using li-ion cells. A minority thankfully.

Hobbyists have been using high discharge LiPo’s for more than a decade. A single puncture and it’s on fiery, uncontrollable fire. There are no regulations and anyone can walk into a RC store and buy them.

I guess the fuss behind Li Ion specially 18650s is how mainstream they have become but the flashlight industry only makes up a very minor portion of the accidents. The result is integrated battery packs flashlights that are much more expensive, but supposedly “safer”.

Guys it is South Korea. They can enact any law(s) they want in their own country. Unless you are planning to move to South Korea why is everyone in a twist?

Ah, yes. The old "My baby! My baby!" argument wins every time.

You guys understand they just want people to use protected cells?

I have a middle-aged son who keeps slinking back homeward due to lonelyness(claimed) but more likely laziness. If I openly charge, discharge and otherwise use lithium ion batteries in indescriminate ways, might that be enough to drive him out of the house?

Wellp, you can just get a pair of shorts and swim-goggles (ie, proper safety equipment) as well as a hammer, axe, other tools, and test the resilience of various 18650s. The resulting fumes’n’flames should do the trick.

Barkuti · 2019-11-24T06:53:55.000Z

Wellp, had to make a comment in the above linked video. :))

Does anyone from LG/Samsung goes to jail if battery/fire explosion happens in their phones, not by users fault? For some "strange" reason they don't mention or show battery fire videos of their phones when users are not the cause, but their design fault. So this video is probably created to try to shift all blame to users when future accidents happen.

Valynor · 2019-11-24T16:42:44.000Z

Why do y'all feel addressed by a video that's clearly NOT targeting your jurisdiction?

Bearbreeder · 2019-11-24T18:30:23.000Z

Its the unprotected mafia feeling like they are oppressed

make protection circuits that can handle upwards of 15A and are compact enough for our purposes and i’ll be all over them

All that needs to be said on the matter. There is fault when uninformed users buy the cells but not when the manufacturer knowingly and willfully sells a defective product containing the cell. Says a lot about the influence of these tech megacorps on the already shady ROK govt.

While possible, an external protection circuit will always pose some sort of burden. Some circuits with additional 8205 MOSFETs or whatever sort of meet the figure but the voltage drop and thermal impact is noticeable.

To me current cells are safe because I am safe, period. Designing a cell dumbass-safe poses additional requirements which could or may be met by newer technologies, there are many already but the market needs to evolve. Despite all of this the actual solution is to raise the vibration of dumbasses into enlightened, knowledgeable and responsible people.

Excuse me but what does ROK govt. mean? I guess it doesn't means a government which rocks, does it? :-D

Whether you like it or not it is always best to develop the best possible beliefs government (and everything) wise, this may be a challenge for some I can understand.
