Whats scarey here is the amount if energy stored in smart phones. Pagers hold a fraction of the energy and the application here to the smart phone is the same.
I read in a NYT headline that they were pagers with explosives added in.
Here's the article I saw but didn't read.
Upvoted for the honesty
If you see the video there is no way a battery behaves like that, even if you drive a nail into them they more rocket flames than explode (I used to work in a battery lab).
I should clarify, typical cells won't explode, you could defeat safety features for pressure release in a can cell but at that effort they would have just added something more energetic.
I doubt the lab experience.
Lithium ion batteries do explode, off-gassing and pressure alone can do significant damage when contained. While typically closer to a thermite reaction, conditions determine damage which have been killing people from either heat or poisonous gas. I can point to state occuption work regulators that have a documented case of an explosion while plenty of deaths from battery fires can be found in the news.
