Just a quick clarification (I have run into my fair share of lithium battery fires and been doing a lot of research)
Insulating it from air doesn’t stop air from getting to it. The battery has all the oxygen (air) it needs whether buried in sand, deep under water or out in space to continue it’s catastrophic failure. The goal for being in sand, or having it suspended in an apparatus like one of those pouches or bags is to hopefully reduce the damage it does to the environment around it.
The more people understand how we really have no control once that thermal runaway starts the more people can protect themselves and hopefully find ourselves further away from these shitty ass designs.
Switching to LiFePo and making the batteries easy to swap along a trip, is a better way to reduce fires.
Or solid state maybe? Not sure how flammable they are, but I know LiFePo are much lower risk than standard lithium ion (Nickle cobalt or whatever Tesla and the big Chevy trucks use )
I know NiMH are way easier to charge, but lifepo4 has better capacity and way more charging cycles I believe.
The tricky thing with iron phosphate is that the voltage level between 75-80 and fully charged is very flat, so it’s difficult to reliably know the state of charge.

Edited for spelling
Solid state batteries are much safer, but much more expensive to make in facilities resembling chip fab clean rooms.
I started exploring more LiFePo4s, NiMH are sometimes a safer bet. We don’t have many options out there unfortunately.

All EVs should have plumbing and an external water access point for firefighters. The current sealed designs are impossible to extinguish.
