First attempt at Li from +123 Cell


LOOK ! .... Lithium under oil !


Lithium_from_123_cell.jpg - 813kB


There is a length of glass capillary tubing holding it down :P

Next time I will try to get a shiny sample :D

Energizer ultimate lithium cells only use the lithium cell to make a longer lasting battery, in this case the 1.5 volt AA, not how much power they put out. Think about it, most people need 1.5 v batteries more than the 3v button batteries. Also, nothing is made to take 3 volts that has a place for a AA battery and vice versa. Essentially (im rambling now, havent had my morning tea) they wantes a better AA battery.

That isnt a fatty oil (vegetable, olive, canola oil) is it? Otherwise you have ruined your lithium and turned the oil to soap.

It's an interesting idea but then how do you clean your lithium from the paraffin ?
I dont doubt it can be done, just unsure how messy and efficient it'll be.


In British English sometimes kerosene is called "paraffin" and Americans confuse this for the wax. I'm almost certain this is what's meant by keeping Li in paraffin.


Both should work, and I do think he meant the wax.

Have you tested to make sure that is lithium? It looks like it sunk in that oil, unless it's stuck in the tube, and that makes me a little skeptical. Congratulations if so!

He's holding it down with a glass rod.

Also, that most certainly is vegetable oil. I can see the oil around the lithium saponifying and the lithium falling apart. Also, it doesn't look like you put the oil under vacuum first to remove the oxygen. Bad juju.
If you care for your lithium, remove it now, wash it with toluene (not water, obviously, I did that once not thinking as a beginner) and store it under something that wont turn to soap. It wont even be useful soap, lithium soaps are only used for mechanical lubricant! It also smells like crap.

The 'oil' is kerosene, some old partially polymerised stuff that definitely has .
Nothing was pre-prepared, I just did it to see what will be required to do it 'properly'

Most of the corrosion is due to air, I undid the battery under kerosene,
even when oily (keroseney ?) a brief exposure to air blackens the surface.
Most of the foil remained shiny but I exposed the entire foil to air when I rolled it up to fit the test tube.
A little of the corrosion does seem due to 'stuff' in the kerosene.
(aldehydes, water, oxygen, nitrogen ?)

I initially stored the test tube upside down to keep the lithium below the kerosene,
but some small bubbles slowly formed
and I started to imagine a lithium/kerosene rocket :o

Edit : Corrected the aldehyde comment

Ah, my bad. It looks a lot like lithium under vegetable oil! (Cause I was stupid and did it once.) Im glad that you tried with the kerosene and impressed at your devotion to disassembly under it! I found that you didnt have to untill you got to the point were you unroll the electrodes. Did you experience the rotten eggs smell emitting from the iron disulfide?

I did not notice any smell at all other than kerosene.
(mostly done under kerosene in a 250ml Nalgene beaker, and I tried to avoid exposure
also, my sense of smell is not as acute as it used to be)

Thinking about it, I made another error,
- using some of the kerosene that was contaminated with electrolyte for storage.

If someone wished to use paraffin wax then I think that would be almost as easy to clean off as kerosene,
but the elevated temperature would make corrosion by the atmosphere quicker,
I guess.

P.S. After removed from argon/oil sealed 1oz. sachets I also store sodium under kerosene,
as it seems to be more stable than the vegetable oil that I first tried :D

I wraped mine around a copper pipe which gives it weight to push in down in the solvent. I find if i let the metal float it oxidizes quicker.how about butane does any one know if lithium sinks in butane .248 for butane and .543 for density of lithium the butane holds well in a soda bottle

Butane is a gas...

This is embarrassing yes butane is a gas i ment to say methyl ether but i dont know where you would get that

Sorry butane liquifyes onder pressure thats why i mentioned a soda bottle which is designed to hold pressure to keep the buane liquid only way to get the lithium out is by keeping it cold which is useful if you are making lithium hydride.thats how i store mine

Wish DMSO was more volitile and less dense because that would be perfect and it is a compound that is used in lithium batteries


Here is extracting lithium from lithium air button cell batteries
https://m.youtube.com/watch?v=Gc-kRTb4Dcw

Just need to hydrogenate the tithium metal
And have lithium hydride

I think powered titanium should help this process and help keep the lithium exposed to the air. And it can form titanium hydride

Liquid butane from lighter refill cylinders is fairly easy to contain at RT
I use it as a dielectric in my high voltage probe,
filled once, never leaked, just a screw cap and a rubber seal.

Butt in this case I do not think that it is worth the added risk.

I'm pretty sure it's because they use different chemistry, and hence the reason it contains lithium metal rather than just ions.

No, they both do contain lithium metal but one is lithium and i want to say manganese dioxide and ammonium chloride and the 1.8 is carbon disulfide and something else. I don't know maybe both are carbon disulfide. But lithium is in both.

I am not deep into this thread but do be aware that lithium metal batteries vs lithium-ion batteries are two very different beasts.
The first allows you to pull lithium metal out directly, the second means that if you are not a wizard, you will get exactly zero lithium metal.

Good point. I am unfortunately not a wizard. I thought he was talking about the 3v lithium button batteries.

Wow thats alot of inquotes its pure lithium metal you can scrape it off with a screwdriver it acts like clay except when it is on fire.
It is really stuck to the inside casing atleast the casing holds the lithium under mineral oil.
Im surprised others dont use 3v lithium button batterys
Not much lithium but it is a great sample size
nail clipers can be used to pry open lithium button batteries takes some practice but it only takes a few seconds and tge lithium is out.

Button batteries are the first kind I ever dismantled. Agreed, a good sample size.
