The problems with those batteries are that cell phones pushed the limit such that they were dangerous due to thin walls between part of the battery(ies), and hoverboards didn't keep batteries from overcharging, which causes a chemical reaction forming spikes that penetrate the thin walls between the parts of the batteries that cause fires. The batteries tech itself is not a problem; it's the design around it.

And if you think this is bad, just wait until batteries get more powerful and there are problems. Be thankful that it only starts a small fire!

Lithium-Ion technology is pretty well-understood at this point.

Just remember that there are 10s or 100s of Billions of Li-Ion batteries around the world, and having a single one fail catastrophically is still enough to make headlines...

Tesla has lots of experience packing cells with their vehicles. I would trust them to get it right. Also they have much more space to work with versus a phone.

I wonder how the safety of this will compare to gas: http://bloximages.chicago2.vip.townnews.com/qctimes.com/cont...
