Usually I'm using them on festivals to charge my phones and to hear music when camping etc., but I have much more than I need at the moment.
Any Idea if it's possible to get the Lithium out of battery (more or less) safely?
I've once obtained some Lithium from Energizer one-way batteries which was quite easy (hhttps://www.youtube.com/watch?v=BliWUHSOalU) but LiPo
batteries are said to be the extremly dangerous https://www.youtube.com/watch?v=gz3hCqjk4yc
Has anyone experience with 18650 LiPo cells?

You can only get lithium out of the Energizer Ultimate Lithium batteries. Unless you want to resort to electrolysis, there's no way to get lithium
metal.
Speaking of which, do those Energizer Advanced Lithium batteries work for extraction as well?Lambda-Eyde - 18-6-2014 at 11:04
There's no lithium metal in Li-ion or LiPo batteries, only in batteries marketed as "lithium batteries".Zyklon-A - 18-6-2014 at 11:52

That's not true, I've found plenty of non-namebrand batteries which contain metallic lithium. Many of them are cheaper as well.
However, the batteries OP has do not contain Li. Rechargeable Li batteries contain compounds of lithium rather than elemental.Brain&Force - 18-6-2014 at 11:58
There are non-name brand lithium batteries? I hope they're cheap. I thought Energizer was the only one making them.

Thank you for your answers!
I've googled around a lot and found that 18650 cells do contain LiMn2O4 or LiNiO2 or (in most cases-) LiCoO2 on aluminium foil as cathode and graphite
as anode. Check http://www.dissertations.se/dissertation/7f55f4f1e7/ for more scientifc stuff - or here's an interesting (but very unscientific ) video how these batteries are made https://www.youtube.com/watch?v=6vBH6zlrXuM#t=230
Any idea what to do insteresting with that stuff (LiCoO2)? (Organic chemistry at best?)

I read in wikipedia about Li-ion batteries (https://en.wikipedia.org/wiki/Lithium-ion_battery) that: "While charging at temperatures below 0 °C, the negative electrode of the cells gets
plated with pure lithium"
It seems that the electrolyte they use allows one to electrolyze lithium metal without having to work with molten lithium salts or Castner cell. What
do you think? Is it possible to make lithium metal by electrolyzing lithium salts dissolved in ethylene carbonate (or whatever electrolyte those
batteries use)?Texium - 1-11-2014 at 09:47
Hehe, sorry for the somewhat off-topic-ness, but I was just reminded to say that the first time I saw LiPo battery, I thought it meant
lithium-polonium. When I found out what they actually are, my feelings were a mixture of relief and disappointment.
