Except those fundamental limits are far higher. The fact is that hydrogen stores energy at 120 MJ/kg. Even at 5% weight efficiency, that’s 6 MJ/kg. Or 1,666 Wh/kg. At 10%, it is 3,333 Wh/kg. Far beyond any battery.
Your link is seriously lying. 8x is the gap between lead-acid and li-ion batteries. The claims are simply impossible. The author must be unknowingly comparing lead-acid battery powered cars to li-ion battery powered cars. I cannot see any other way his claim is true.
A lithium-air battery is literally a fuel cell. In fact, what did you think hydrogen fuel cells were this entire time?
Driving with something that power dense is incredibly dangerous. You’re literally driving a bomb, dynamite is 4.6 MJ/kg
On one had we’ve got links to the department of energy and to Wikipedia. And just some hand waving on the other hand.
It’s wrong because li-ion batteries at the time were way better than what it claims:

This is from 2009, and already we reached 675 Wh/L. So there’s no way the DoE link is true.
