As someone who’s accidentally punctured a large lithium ion battery with 100% charge I can tell you that explode isn’t exactly the right word. While I’m sure you could create an enclosure that could explode from the pressure, the battery itself just kinda shoots out a small jet of fire along with some toxic gas.
I didn’t reply to this, but part of the reason why people type Reddit after a search is because more often than not it will yield the most useful results. This comes from the age and userbase size of Reddit. If you tried to do this with Lemmy odds are a good amount of the time you’ll end up without results or with less relevant results than from Reddit.
