okay (wen i get to doing this again ill put it on my site), anyways, you take a AA lithium battery. And you cut off the bottom cap of the battery. you then take a flame (blowtorch would be best) and strongly heat the back side of the battery away from the openeing. you hav to be careful not to touch the lithium with the flame since it will ignite. ok, so you heat it, then the lithum will melt and ooze out. take some pliers and squeeze the battery like a toothpaste stick- the molten lithium will pour out and then you can collect it (you could drip it directly into oil probly). wen in the molten state its very pure, the rate of oxidation after that depends on how fast you put it in oil or watver.
