K2 out of Las Vegas has a Shelby Cobra EV that is powered by Lithium Iron Phosphate (AKA Life or LFP) which theoretically  should increase safety because of the less volatile chemistry.

My friend who works for a battery company was not at all surprised by the video when I asked him about it. He said lithium-ion can be very volatile, that is one reason why the lithium-iron phosphate battery is getting popular. It doesn't have nearly the energy density as some of the Li Ion but is not nearly as volatile. It is also available in a flat-pack or prismatic cells which are already found in the newest motorcycle starting batteries. Some of the EVs are switching from Li Ion to Life because of safety.

for those interested, here's a video of a car getting set alight just by static

No fun at all.

As techochip said, gasoline is also a proven danger in cars. I wouldn't put a lot of credibility in a guy who does a dangerous "experiment" (??) without any protective gear as this guy did.

Then again that much gasoline, liquid propane or hydrogen would make a good flame too.  I've also seen videos of people shooting cells with a rifle and shorting the leads without any problems.  Much like Edison's campaign against AC, it's a matter of what you want to demonstrate.

I've said it before and I'll say it again; I had a lithium battery blow up in my face.  The chemistry goes from docile to explosive without the slightest hint of danger, so you really need to exercise great care around lithiums.

In this video the hammer blow probably caused an internal short in the bag style cell.

This just reminds us of the risks of the new electric cars.  No thank you!

How do you feel about riding ON a flamethrower!

Chuck, that was amazing.  One hit and the thing went up in flames. 

Obviously most batteries for PCs are not the flat pack variety, so they may not react the same way.  I wonder if the battery has to be fully charged to burst into flames.  I have some old cell phone batteries, one of which started to bulge (so it was replaced).  We recycle batteries here, so I would not keep them around.  Good thing, it seems.

Cigarette companies are fighting back by buying up e-cigarette manufacturers.
