Here's a demonstration video of what can happen when a lithium ion battery explodes in a laptop. The video is a little slow so you'll probably want to click forward past some of it. In any event the first 'cell' in the battery explodes releasing some smoke and damaging the casing. The next cell explodes because of the heat from the first cell and blows a hole in the top of the cashing. Each cell explosion is progressively worse than the last one with the fifth or sixth cell explosion throwing out a pretty good size jet of flame.
