Shrapnel, no, but Lithium-Ion does explode. Especially on a full charge
No way did lithium batteries kill eight people.
I did not say they did, but they can explode violently

Yeah, being trapped in a lift with a burning Ebike battery sounds like not much fun at all.
They have over-pressure vents and will vent pretty violently and catch fire, but should not explode due to pressure build up.
They still explode in some cases. Plenty of clips of li-ion not just catching fire but exploding similar to how a firework might explode.

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.
