Al - the case
S - probably a component of the Al alloy, it helps with machinability
Li - the battery, possibly also the case alloy
B, P - semiconductor doping
Cu - Almost certainly used somewhere
Pb, Sn - solder
Anything else?

- noir_lord 13y agoNot much Pb in modern solders (in fact in the EU you can't add lead to any solder, I think you can have trace amounts if they are "naturally" there). Modern solder is pretty crappy compared to the stuff I used to work with in the 80's and 90's, it's much trickier to work with, whiskers are more of a problem and I've found (the few times I've used it) that it seems to require more heat.
