Say NO to Lithium Ion Batteries

[FrankenMech]

This is just another example of why people should decline to use lithium-ion batteries. We need to step back and ask if the increased capacity is worth the risk. I have a single cell in my phone and I don't like it, especially since it resides in my pocket. I just hope I have time to get it out of my pocket and thrown outside b4 it blows. I don't even want to use lithium-ion cells in my tools. The Ni-Cad batteries have plenty of power and capacity for me. They may be heavier and larger but I can live with that. Litium-Ion batteries should be outlawed.

Watch the video:

That is a real time display of what happened.

Li-Io (LiCoO2) batteries can indeed be dangerous, but don't mistake them with Li-Fe (LiFePO4), which is the composition in scooter starter batteries from quality brands like Shorai. The Li-Fe compound doesn't explode like Li-Io. This way you can get much of the weight savings and power of a Lithium cell without the inherent danger. Food for thought.

Here's the Wiki: en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

RC airplanes and drones. Gotta have em for those.

Also, unless it's not true, I heard pretty much all commercial airplanes use them exactly for the weight savings.
Think about THAT next time ya Fly .

But I hear ya.

They will get the recipe sorted out or some other material will move in next.

We used to use Ni-Cad for RC and other flight aps. I think they should go back to them even if there is a higher weight penalty. The article talks about other uses also:

Exploding lithium-ion batteries are not new news. Last year’s hottest Christmas present, the hoverboard, was a bit too hot. You can’t take an e-cigarette on a plane because it might combust in the cargo hold. And if you have a Samsung Galaxy Note 7…well…better luck in your next phone pick.

They are working on a Zinc-Manganese battery also.

I use Lithium polymer 18650s in my Vape. (Mod)
They can be very dangerous when not used correctly. But with good brands (Sony,lg,etc) and (good batery practices) I've managed no incidents for my over two years of Vaping.

I believe they had problems with them in the new Boeings

I once saw a youtube video of a li-ion battery, powering a bicycle, burst into flames. It was mounted on a rear rack. The fireball was big enough to engulf the riders upper legs, abdomen and so on.

Now that big fireball did dissipate pretty quickly. It shrunk to a fireball that was perhaps as large as a volleyball. But even on a low-res computer vid, I could see that that fire had some strength to it. It wouldn't be easy to put out.

The big fireball was gone quickly enough that I'd say it likely wouldn't have actually burned the rider. But it sure could have caused him to crash. And the small fireball surely destroyed at least the wiring nearby. Whether it was strong and hot enough to weaken the bike frame is hard to say. But if it were my bike, I'd consider it to be toast anyway.

I do hear that lithium-iron-phosphate batteries are a good deal more safe. I sure do hope so because I've got one on the way. It cost six hundred and some dollars. It's to power an electric bicycle.

I've been pondering it for the last few years. I simply didn't want to spend that kind of money on something only to find out that it's not what I expected. That's happened before.

On the other hand, nothing ventured nothing gained. So I pulled the trigger. Hope it works out.

You're probably FAR more likely to be hurt by a bad driver texting while riding your scooter than to have a LiPo fire.

I have a number of LiPo's for my RC aircraft. SFSG.

Cincikid has a good point. "Proper" care and use can greatly reduce risks.
Overcharging is one of the dangers. You gotta have a good reliable charger.
Damaging the battery is another. If it's internally compromised a fire can result.

Discharging them to "storage" charge reduces the risk.

I try to store mine in fireproof metal boxes. Sometimes I forget.

There's a risk. But think about all the electronic devices plugged in all around your home....You're always one tiny short circuit away from disaster. RISK MANAGEMENT is probably a good term.

[FrankenMech]

Most of those electronic devices around the home have some sort of short circuit overload protection but not all. Many home fires are started by wiring, unsafe wiring or practices, those ubiquitous extension cords, or device faults. I have had a few close calls over the years. Lightning strikes, a ceiling fixture with larger than specified bulbs in it (from the previous owner), and a box fan power cord that got brittle with age.

Risk management is a good term.

Those fireballs are a type of plasma explosion and are very hot. They may also embed hot reactive components in items they touch, think napalm or phosphorous. Polyester clothing is extremely flammable also. When it is heated it melts and adheres to the skin.

These batteries are much, much safer.

From what I was reading about the Galaxy Note 7, they either made the phone in such a way as to squeeze the battery too hard and caused internal problems or the Galaxy Note 7 accidentally trickle charged the battery too much and little sharp spikes developed inside and created the shorts that then led to fires.

Here's where I got this info.....

Why are Samsung Phones Exploding?

I think I may cancel my order of Li-Io powered electric heated underpants.
