Title: laptop battery as source for lithium?
Post by: meticulous on August 15, 2002, 04:58:00 PM
SWIM was about to toss his 'only holds a charge for 5 minutes' useless laptop battery in the trash, when he noticed it was a lithium-ion battery pack. 

Would it be worth anything for lithium recovery for a certain german style reduction?

I have done some searching for info about the Li-ion tech and my impression was that these batteries did not have any sort of recoverable strip of lithium metal.

Thought the same thing with the laptop batteries...So the disection commenced.  A very wide and long strip was obtained.  (Actually, two strips of unknown identity).

A small piece of both strips was removed from the strips in the NP.  Patted lightly with a paper towel, and then thrown into a bowl of water.  One of the strips instantly started skipping on the surface of the water and displayed the exact same chariteristics as Li from a known source.

Now on to step two:  Actually trying the obtained strips in a actual rxn.
Why is there never any positive news stories about drugs?

Well, if it was a Li-ion battery then neither of the strips was pure lithium metal.

In Li-ion batteries the lithium is stored in "intercalated" form - interspersed with carbon atoms in a sort of crystal. I suppose that in a charged Li-ion battery that this intercalated lithium might be available for use in a Birch.

Much easier and cheaper to obtain it from lithium carbonate.
Yes, That pic really is me!

Please, tell us how.
