Even lead acid batteries can cause fires.

Here's a story about a 1968 bug, with a battery under rear seat. Caught fire from seat springs shorting out the battery. Car is a total loss.

That link says laptop cells, which means LiCo, not LiFePO4.

From the article

We now use Panasonic lithium ion phosphate batteries," explains Charleson Meridones, one of Sikat IIs young engineers.

But shouldn't that be "iron" not "ion"?

It's rather confusing. Since LiCo seems to have twice the specific energy density of LiFePO4 I'm not aware of any laptops using LiFePO4, though the "laptop" reference may have just been referring to the 18650 format.

Right now there are only two main types of lithium ion phosphate battery chemistries on the market, lithium iron magnesium phosphate and lithium iron phosphate. They are both very similar and one is just as stable as the other. Lithium iron magnesium phosphate is slightly more efficient however.

There are a lot of types of lithium ion batteries, with lots of different formulations:

Lithium-ion battery - Wikipedia, the free encyclopedia

Some with iron, manganese, cobalt, air...
