I have a 18650 out on my drive that is bubbling, what should I do with it!???

Have spent the day cracking open laptop packs, with some great success so far- however one I just opened a single 18650 started bubbling in a small 2mm area of it.

It is currently sitting out on the concrete driveway, what exactly should I do with it- is it safe to move/take it to a battery recycling drop off??????

I carefully touched a multimeter to it and it reads 0.01v

Yikes, that’s very dangerous.

I say you could very carefully bring it to the recycling center.

You should be prepared to toss it (literally) when it gets hot. The damaged cell may vent.

Dump it in a bucket of salt water, and leave it for a week.

Shit... Ok, stay away from it and do not approach it for a long time, preferably atleast a day. If what you said is true it is venting extremely dangerous fumes that permanently dissolve your lungs.

You could send it to one of the members here who profess lithium-ions to be harmless...

Wow appreciate the quick replies!

I did think of taking a video in case it exploded lol, but I’m too scared!

So salt water- um can I just dump a cup of normal salt into a bucket of water for this?

After 15mins it has stopped bubbling and now reads 0.13v (tested with a full body suit, gloves and goggles 8) )

@FMS, that may be the thing to do later, but now is it's most active/dangerous phase, just leave it out there for a bit.

Thats my plan short term, however it looks like it’s about to rain so I’m guessing that won’t help

Yes, probably better to leave it for a few days.

Any idea how this might have happened?

While the rain won't help, either way it sounds like this cell will vent so there is really no harm.

DON’T do that though!!

No idea myself, I’m 100% positive I didn’t puncture it as I’ve perfected pulling laptop packs apart at this stage.

I took a pic (using a big zoom lens so wasn’t near the battery), the arrow points to where it was bubbling (shiny spot), I circled what looks like a dark discoloured patch that was on this cell and the adjoining cell when I removed them.
The four other cells are not discoloured like this and measure above 3.5v- on that note does anyone see any reason I shouldn’t use these cells that measure well?

Actually, the electrolyte solution in the cells isn’t that nasty. It is a flammable solvent, though. Once a cell is discharged to near zero, the chances of it having enough energy left in it to ignite the electrolyte is rather small. The salt-water douche is a good way to discharge the cell fairly slowly and safely. I prefer a, uhhh, more direct method. J)

@Texaspyro, I may be mistaken but I read somewhere that they can vent hydroflouric acid, or was that only for lithium primaries?

If there was HF in there, the shell and copper and aluminum electrodes would be dissolved. You might get some HF if the electrolyte torched off… would depend on the electrolyte.

I have a friend that tortures batteries for a living. He would be long dead by now if there was something really nasty going on.

Well of course it is not actually in the battery, but I know there were a few HF incidents on CPF due to vents.

Scaru, I believe it was a CR123 primary cell in the thread at CPF.

Here’s the thread: http://www.candlepowerforums.com/vb/showthread.php?141137-Inhaled-vapors...!!!

HF is produced at burning. No flames/smoke, no HF

Call the fire brigade.
They have specialist hazchem units who will let you know if it’s actually dangerous,
and how to safely dispose of it.

How the hell can a cell start to bubble? Are we sure its venting or just getting really hot?

I'd let it sit outside for a few days (dont throw it onto the lawn and run over it with a lawnmower though) and then try the saltwater method. If you have something like this, you should be really safe:

Pressure differences pushing electrolyte out of a tiny leak in the seal/can.

Could be expensive if emergency services later sends you a $1,000 bill for their visit. However, I suppose just calling them to ask for info should be free.

Thanks for the suggestions, both dodgy cells are currently now sitting under a 20kg solid conrete plant pot, will dump them into salt water in a few days time.

Good idea I might call the fire brigade and ask them where to dispose of them.

You could send it to the guy who posted on here yesterday about how to disassemble a li ion cell, he already cut the top off one, he is a graduate student or something.

Send it to me  Silly

  I think if you tested it at zero voltage it's a door stop  why does anyone freak out about a dead cell .unless he went back and edited his post .

 It says he tested it at zero volts ..That doesn't scare me ..Should it ?   check voltage and if it's dead or very dang dead ..Wrap them separately in little plastic tape them up  and recycle them . killer gases comes from the batteries on fire  not sitting there doa with no voltage . i ain't scared 

If i saw a battery bubbling ... it might get my attention 

 

 if I'm wrong ....i'd like to know

Tell me Cat eyes, you use “LSD” Cells to keep you going, don’t you. Just curious, do you insert them Nasally, Intravenously or Rectally. Smile

just because theres no voltage doesn’t mean everything inside is in its lowest energy state, it just means the chemical reaction isn’t producing electricity, i don’t know much about lithium battery construction, but if there are chemicals that are reactive then you could have a problem, say acids, hydrogen, pure oxygen, materials incompatible with water, air, calcium, magnesium etc.
Hydrofluoric acid is a good example, i’m not getting into the debate of if its in batteries or not, but its an example of something that may not produce electricity, but is still harmful no matter if its sourced from batteries or aluminium etching solutions.
