Batteries
Could someone please either direct me to a good video on how to dissect button cell batteries or explain it? And if you could also include the
dissection of Zinc carbon D cells

Any tips or good sources are welcome.

Nurdrage has a good series on disassembly of a carbon zinc lantern battery and the recovery and purification of the manganese compounds in it.
There are plenty of vids on recovering the lithium from an AA battery. Button cells with the same chemistry are going to be fiddlier and give a lot
less of useful things. Why did you want to do this? If it is out of curiosity, then grab a screwdriver and have a go yourself. If it is to get
something from inside, then good luck. There are better places to go for that.

A short list of compounds that button cells use that are useful, Silver, pure oxygen, lithium, and mercury

The only reason why I ask. Is because I have several LFP batteries and CdNi batteries I also want to dismantle for materials. For element collecting

Then you and I are on the same page. I also am looking at element collecting. But I have not looked closely at button batteries.
Li can be obtained easily from an AA lithium battery.
Silver -- buy silver wire or get it by purifying old jewellery.
Mercury -- I think battery manufacturers have been doing all they can for decades to ensure that mercury levels are extremely low. If you want OTC
mercury then buy a mercury tilt switch or thermometer. Or get on eBay for an old sphygmomanometer.
Oxygen is not going to be found inside a button battery. Oxygen-containing compounds might. But again, there are better sources. To my knowledge,
the simplest way to obtain a stream of oxygen gas is to use a CoCl2 catalyst to decompose household bleach. The O2 will be wet but you can dry it by
standard methods.

For wet oxygen, decomposing OTC hydrogen peroxide solution is cheap and viable, as is using sodium or potassium chlorate.

Yep. Except that the maximum available locally is 6% and the cost is comparable to gold bars. I have cobalt chloride and bleach is cheap.
Therefore, this method is better for me. Of course it all depends on what is available where you live.
Incidentally, I understand that some lithium batteries contain a quantity of cobalt that can be recovered. I haven't seen it myself though.

don't forget Ni and Cd are still around if you can find some old rechargables.

I'm only concerned about the electrolyte. I'm a minor and my parents don't want me getting hurt. They won't let me unless I have a procedure that a
chemist has approved of. They are worried about the hydrogen inside some. I also lack any equipment.
