Honestly, I had already punctured a cell and advertently got a whiff what came out of it, which seemed fairly harmless compared to some of the other chemicals that I work around in aviation. I had forgotten to reset my spot welder to a lower setting and blasted right through the end cap of a cell which proceeded to spray electrolyte on my hands. It actually smelled like salt water. If you ever puncture a lithium ion cell, you'll get a pretty strong whiff of very toxic chemicals. These are nothing in comparison to lithium ion. But you are right, I should be more careful. 😁
Thanks for running these safety tests! The world benefits from your work! Remember to wear an HF rated respirator so your lungs don't get Flurosis scars like mine.
even though it may not smell like the lithium-ion sweet smelling electrolyte, its definitely not a safe electrolyte to breathe in. youre either dealing with sodium perchlorate which is toxic, or sodium hexafluorophosphate which is corrosive. i hope that most cells move to perchlorate since it has the least environmental effects and should dissipate quickly.
I didn't observe any corrosion after the fact on the tools for the screws involved. Whatever they're using it smelled more like saltwater than anything else.
They seem to explode just the same, but, they don't seem to create the fire. They're not perfectly safe, but, much safer than Li-Ion. These are more like Lithium Iron Phosphate. (LiFePO4)
of course these can create fire. battery safety is all about energy density and pack design. if you bunch these close together they will happily burn until nothing left. but with proper mitigations they will be as safe as LFP due to their similar energy density.
I bet. I orded two agms for my car audio last week. I've never had a single issue with agm in the entire 16 years I've been using them. You would get signs of swelling on agm if there were an issue. Lithium likes so smoke and ignite for multiple reasons or just randomly.
@@11onejay lead acid batteries can explode as well, and unlike lithium, they spew acid everwhere. dont short them out. any form of energy storage has a risk to it.
You should dissolve sonevof the material in HCl and burn it (outside) on the end if a wood splinter or on a piece of nichrome wire in the flame of a propane torch. Probably when the sun's going down so its not too bright out. Sodium flares yellow, lithium flares red.
I wish we had temperature measurements. I'd like to know how much energy is released when it fails so I know what materials are safe to use around them.
@@SuperBrainAKthat might not be the entirety of it. Lithium Ion cells release a lot of energy from their thermal decomposition. More than their nominal capacity of electricity. I suspect something similar is going on here, see the black burn make and the bang from lots of gas being generated?
Keep in mind that this is one single cell. Now imagine a large battery pack with hundreds of the cells wired in a series parallel configuration. I’m definitely curious how these would react as a battery pack in a thermal runaway condition.
I think that the issue is the stored electricity. A very similar thing happens with a capacitor. There is no way not to have any danger making a hole in something with electricity inside.
Manufacturers saw my video and gave me that link. I don't get anything from it and I don't really want to get in a position where I owe anybody. So I don't really get anything from this link
im staring down the 200Ah 12 volt sodium ion's from ali express like a hawk . import fee would be ridiculous tho because its on the regulated list. waiting for north american made i guess and standard shape for car truck boat etc. incredibly safe in relation to lithium , self extinguishing even . :)

tenha em mente que perfurar rapidamente a célula da bateria com um prego de metal condutor resultará em um curto-circuito rápido e em uma rápida liberação de energia. Não importa se é lítio ou sódio. Mas com o sódio não há fogo.
Would be nice to see test if those batteries blow up in short circuit. Edit: now as i watch video again it seems that plywood that was under the explosion is burned. So there is some flame probably
@@diyelectrified1289 yep looks like it produces a lot of heat but electrolyte is not flammable and didnt burn. Or explosion blow out any fire. Tnt dont burn also because ot blows too fast :D did it spit out its internals or just plus connection popped out? Cant really see in the video.
They don't look that safe as Na-ion supposed to be?! I would be interesting to see similar test for 220ah+ Na-ion batteries (for solar/off-grid systems)
Now they explode.... I don't know which version is worse... A lot of publicity, it seems more dangerous to me, burning a finger is not the same as exploding a finger.
seem like LFP is better because LFP just produce smoke BUT this sodiom explode, heat and smoke but no fire. Combine heat and explode still dangerous if its in pack since there will be more heat produce and could ignite fire and explosion.
The smoke will catch fire/explode if enough heat is present, no spark needed. We've had a 30 kWh LFP battery demolish half a house in Germany a few months ago. Google "explosion lifepo4 germany"
That's a good question. I do not wish to sacrifice any more cells. I am planning to do a thermal test but I have to rig up the apparatus first and that might be a while
That's true, but I'm not sure how you would manage to simultaneously penetrate all of them with a nail. If you watch carefully, especially on the second cell, a partial penetration does not cause the catastrophic reaction. It's until the nail completely shorts every anode and cathode layer together that causes the big and sudden release of energy. It would be interesting to see if you can put a fully charged pack with hundreds or thousands of cells into one of those car crushers.
Cool, please wear gloves next time. And maybe some kind of spit shield and front guard so it doesn't fly upwards towards you. Is there any lithium in there?
To me it seems the main problem with these cells is there is no pressure relief valve. So instead of just rapidly venting they blow the positive end of the cell cap off.
The source is a fake manufacturer, hakadi does sell genuine EVE sodium ion. Price is not interesting yet, but will blow LFP when it will be mass produced.
Oh FFS why didnt you hold the battery firmly in position and have a the nail on a weighted swing arm that released to hit the battery squarely - too much trouble
If that's true, how would you then explain their ability to go down to almost zero volts and then fully recover? Also, how do you explain that they do not catch fire? I humbly disagree with you and I fully believe they are sodium ion cells.
@@diyelectrified1289 fair points, i didnt see your charge or discharge profiles or capacity loss. so i cant speak for that. The catching fire phrase is misleading. Sodium ion and Lithium ion both go into thermal run away. In its most basic definition "uncontrolled self heating, or creating more heat than it is dissipating". Thermal runaway does not equal fire and vise versa. Fire is started with oxygen, fuel, and an ignition source. you need all three. By doing the puncture test, you are creating an internal short and rapidly heating up internal components. pushing the cell into TR. The Anode reacts with the electrolyte and generates a decent amount of heat and large amounts of gas, when the heat gets high enough the cathode reacts with the electrolyte and breaks down increasing more heat and even more gas. This is an extremely over simplification of TR. Those gasses are composed of a bunch of nasty things but to keep it higher level lots and lots of H2 and hydrocarbons (fuel). *side note: yes some oxygen is produced in this reaction but the amount is highly debated and in my personal experience, not enough to keep the combustion reaction going for more than a few seconds.* So you now have high quantities of fuel and a spark and plenty of oxygen in the atmosphere.... but that O2 and fuel mixture needs to be in just the right amount of ratios to have a fire start. that reaction is happening so fast that its surprisingly difficult to get that in that small of a time frame. (longer time frames, more cells, and additional ignition sources, ie from modules or car electronics... different story). All of that being said you still potentially did have a fire right there, you just didnt see it. it could have been an H2 fire that burns clear, or your camera frame wasnt fast enough to catch it. All in all my first argument is about the cell voltage. I have never seen a sodium ion cathode that goes up to 4V. sodium ion cells are known to have lower voltages than your "regular" LiNMC cells. LFP cells only go up to 3.6V. the highest numbers ive seen on a sodium Ion cell is 3.3V. On a different note, please make sure you are wearing an organic vapor and acid gas filter while running these tests. Nasty stuff is an extreme understatement.
There are multiple sodium ion-based chemistries, they aren’t all the same and have different voltages. This is still sodium ion but a higher voltage type.
They have the same steel case as any other 18650 cell. So that means the steel will rust and turn into iron oxide and travel around the inside of the battery creating shorts.
Yes of course. A charged battery has a lot of potential chemical energy. It is also slightly larger when fully charged (not a lot but technically it is larger) because of battery swells when fully charged and contracts when discharged. This is one of the things that contributes to the breakdown inside the battery.
@@wasserdrucker6227 If push a ball at the top of a hill, it will roll all the way to the bottom. If you push the same ball when it's at the bottom already, what will happen?
So... no volcano but still not exactly safer. I imagine that explosion could still blow your hand up nice. Not off- but up. So in theory... in a pocket- better but still not great. Car? I dunno... the housing around the cells would need still to contain that (larger in this case) potential explosion. Cheaper than lithium maybe- if it's not squandered and hiked up in price just because it's new. Lipo might suddenly be cheaper because nobody will want them compared to a safer option.... the future sounds bleak with that notion.
@@diyelectrified1289 get yourself a nice capacity tester that hooks up to your pc, then you can graph the voltage curve and clearly tell what kind of cell something is.
Okay they explode in stead 😬 imagine a car full of these 💥 if one damage cell can create a chain reaction, and set off its neighbors of course??? 🤷♂ (Greate Scott 😀)
so is it better that it explodes than catch fire like lithium? I think I would rather have time to get away from a punctured EV battery than being blown up…
It wasn't a controlled test. I hammered the nail through pretty quickly causing catastrophic short circuit. If I had a big budget and willing to destroy more cells I could do a setup where the nail is pushed in slowly like you see in the other LFP tests
Well shiet! I'm kinda disappointed, thought they'd be safer than LFP. No fire however, curious what would happen in a battery pack in an EV. Very likely still safer than NCA/NCM.
Still would not like one of these going off in my pants pocket but at least there was no fire.So now I guess instead of flaming Teslas we'll see (briefly) flying Teslas. Progress not perfection, eh?
Except without all the flame and toxic fumes. Unlike lithium ion which has a model glue kind of smell , there's literally no smell left behind when these things popped off. I bet if I put the nail through slowly or crushed it in a vice it wouldn't rapidly discharge.
Hmm, I think you should have a disclaimer at the start about safety (that you're not doing or showing) or explain this is a comedy video? Either way, thanks for risking your health to show us the dangers posed by these batteries & entertaining us 😂👏🙌

Sodium ion and Lithium ion both go into thermal run away. In its most basic definition "uncontrolled self heating, or creating more heat than it is dissipating". Thermal runaway does not equal fire and vise versa. Fire is started with oxygen, fuel, and an ignition source. you need all three.

The Anode reacts with the electrolyte and generates a decent amount of heat and large amounts of gas, when the heat gets high enough the cathode reacts with the electrolyte and breaks down increasing more heat and even more gas. This is an extremely over simplification of TR. Those gasses are composed of a bunch of nasty things but to keep it higher level lots and lots of H2 and hydrocarbons (fuel). *side note: yes some oxygen is produced in this reaction but the amount is highly debated and in my personal experience, not enough to keep the combustion reaction going for more than a few seconds.* So you now have high quantities of fuel and a spark and plenty of oxygen in the atmosphere.... but that O2 and fuel mixture needs to be in just the right amount of ratios to have a fire start. that reaction is happening so fast that its surprisingly difficult to get that in that small of a time frame. (longer time frames, more cells, and additional ignition sources, ie from modules or car electronics... different story). All of that being said you still potentially did have a fire right there, you just didnt see it. it could have been an H2 fire that burns clear, or your camera frame wasnt fast enough to catch it. All in all my first argument is about the cell voltage. I have never seen a sodium ion cathode that goes up to 4V. sodium ion cells are known to have lower voltages than your "regular" LiNMC cells. LFP cells only go up to 3.6V. the highest numbers ive seen on a sodium Ion cell is 3.3V.

Car? I dunno... the housing around the cells would need still to contain that (larger in this case) potential explosion. Cheaper than lithium maybe- if it's not squandered and hiked up in price just because it's new.
Lipo might suddenly be cheaper because nobody will want them compared to a safer option.... the future sounds bleak with that notion.
Clearly it's sodium 😂
Much easier ways to verify if sodium or not lol
True that!! Though... that's not why I did the nail penetration test. Lots of test online with the other chemistries but not so much with SIBs.
@@diyelectrified1289 get yourself a nice capacity tester that hooks up to your pc, then you can graph the voltage curve and clearly tell what kind of cell something is.
That is definitely on the list.
should use them to launch rockets
Okay they explode in stead 😬 imagine a car full of these 💥 if one damage cell can create a chain reaction, and set off its neighbors of course??? 🤷♂ (Greate Scott 😀)
Sodium 2.9v -3v only per cell anything voltage about that not sodium cell
Well, it's definitely better than liion. It doesn't catch fire, it just simply explodes 😁
so is it better that it explodes than catch fire like lithium? I think I would rather have time to get away from a punctured EV battery than being blown up…
This should be better in a pack, since one blowing up probably shouldn't blow up all adjacent cells...
It's designed to explode like that. Plus, it would be very easy to design the battery pack to aim the explosion towards the ground, or a shield.
They explode? 😂
LFP smoked at best
It wasn't a controlled test. I hammered the nail through pretty quickly causing catastrophic short circuit. If I had a big budget and willing to destroy more cells I could do a setup where the nail is pushed in slowly like you see in the other LFP tests
Accidents with EV will happen suddenly and with much more force than a human hand can do.
I would just skip this tech.
@@jec_ecart It's probably ok for stationary storage, unless somebody crashes into your house.
Well shiet! I'm kinda disappointed, thought they'd be safer than LFP. No fire however, curious what would happen in a battery pack in an EV. Very likely still safer than NCA/NCM.
interesting, so with lithium the case handles the pressure while venting fire, but with sodium the battery just explodes almost instantly?
Still would not like one of these going off in my pants pocket but at least there was no fire.So now I guess instead of flaming Teslas we'll see (briefly) flying Teslas. Progress not perfection, eh?
Maybe hold that battery in a vise 🙄
Yup
less go
What happens if you drop na battery in water ?
nothing
It will corrode.
Reaction looks like a low capacity li ion INR...
Except without all the flame and toxic fumes. Unlike lithium ion which has a model glue kind of smell , there's literally no smell left behind when these things popped off. I bet if I put the nail through slowly or crushed it in a vice it wouldn't rapidly discharge.
Hmm, I think you should have a disclaimer at the start about safety (that you're not doing or showing) or explain this is a comedy video? Either way, thanks for risking your health to show us the dangers posed by these batteries & entertaining us 😂👏🙌
Do you not think the one I have at the beginning is not good enough?
& this is 1 of thousands in a 🚗
