The engineers must have thought this through.
Most of today’s Electric vehicles use lithium batteries.
Recent EVs are utilizing new variations on lithium-ion chemistry that sacrifice specific energy and specific power to provide fire resistance, environmental friendliness, rapid charging (as quickly as a few minutes), and longer lifespans. These variants (phosphates, titanates, spinels, etc.) have been shown to have a much longer lifetime

“The engineers must have thought this through.”
This subject interests me but I don’t follow it closely.
Have we heard the technical reason why the phone and e-cig batteries sometimes catch fire. I presume an internal short that would put a large current through a conductor that would heat up big time.
We put 300amp Li-in batteries on the boat. They keep us with lights and charged laptops as long as we get sunshine during the day.
We are very happy with them.

The Science prizes are still very much a big deal.
