Here’s a cool hack for extracting Lithium out of your Lithium battery for those of you scientists who need some Lithium fast!
First you must obtain some dead lithium batteries. This shouldn’t be too hard, as most people will readily give them away when they no longer produce a sufficient current. Fresh ones will work too, but it’s rather wasteful.
Note that this will only work with plain lithium batteries, not lithium ion. The rechargeable lithium ion cells do not contain the pure metal, but rather a lithium salt.
If you happen to be using double batteries like me, you must break them apart. Simply use a pliers and pry off the spot welded conductor. Those with a keen eye might notice how they are connected in parallel rather than series. This is because the lithium cell produces 3 volts, twice that of alkalines.
