Explosion != Detonation
A steam explosion is still an explosion, and an explosion does not need to involve combustion. I originally included some references to detonation but removed it to avoid confusion.
I said explosion in my original post and distinguished it from burning, all of those points stand. At no point did I or the post I was replying to say detonation.
Functioning correctly, batteries vent, not explode and certainly not detonate.
You're mixing terms when it comes to explosives but I'm not sure it's relevant to this topic, or this forum to be honest. Just one hint though, sensitivity is a separate characteristic altogether. PeriodicVideos on YouTube have some good videos on the subject.
Venting batteries are not exploding in the same way a struck match is not exploding. Let's not overcomplicate it.
