What batteries contain a substantial amount of Cobalt?

Hi all, good afternoon.
I recently took apart an old Lenovo laptop battery to get out the Li ion cells. I got four in the end, and planned on getting some Cobalt from it by reacting the LiCoO2 electrode with 31.45% HCl. I did this, ans got a reaction which resulted in a surprisingly green solution, like it contained lots of Ni or Cu chloride. Not the stunning blue of Cobalt. My question for all of you is:
1. What brands of Li ion batteries contain a substantial amount of Cobalt .
2. What easily available sources contain cobalt, in any form at a high concentration, without any impurity, or very little at least.
3. Is it possible to "read" the plastic casing on batteries to more easily find out what their composition is?

Thanks! :]

Just buy the metal off ebay. It's not that expensive, especially compared to using Li-ion cells or SmCo magnets. It dissolves slowly in conc. HCl to form dark blue solutions from which the hydrated chloride can be isolated.

You see, that kinda goes against the whole idea of getting it out of a source that isn't from online, while still retaining reasonable purity.

Do you have a ceramics shop locally?

Funny you say that, because yesterday I said screw it and went to my local pottery supply store and bought .5 lb of CoCO3. So I guess I'm all good now. :]
