Lets go with the usual reminder: de-soldering / soldering Li-ion cells can be super dangerous. With a bit too much of heat it can fire or even explode...

Hobbyists should buy cells with pre-welded tabs. You solder onto the tabs, not the cell terminals.
It doesn't quite explode. Instead it shoots out a super hot flame that is nearly impossible to put out.
Imagine having a blowtouch that you can't extinguish or touch which is likely rolling around.
That sounds exactly like one of the kinds of deflagration (aka low-speed explosion) that seems worthwhile to discourage people from invoking.
"Hey, the worst case is that you get jets of super-hot flames that are impossible to extinguish!"
Don't solder lithium cells, even if it goes well you'll ruin them. You need a spot welder.
