higher weight ? wonder how much heavier...
also, sodium doesn’t like to get wet...it reacts energetically to release hydrogen, which then
explodes.

so, could this be considered the “ethanol” for EV’s ?
I forget whether the mass disadvantage is 10% or 20%.sodium doesn’t like to get wet...it reacts energetically to release hydrogen, which then explodes.
I don’t think the sodium in a battery is in its pure elemental form. Table salt is loaded with sodium, and I never heard of a salt shaker exploding . . .The natural thing in any EV design is to mount the batteries in the bottom of the vehicle, in a container at least as robust as a gas tank in a traditional car. So if, Heaven forfend, your car collides with a BEV, the heaviest thing in the car hitting you won’t be an engine at your waist height but a battery down at foot level . . . and the front of the BEV is designed only for a bit of storage and a lot of crash energy absorption.
