I’m not sure if these batteries are the type that can spontaneously combust like Lithium, but a battery fire in a thin wing does not bode well for structural integrity.

I'm not sure a LiPo fire under everybody's hind quarters is much better!

That's the other big issue with airplane batteries... pushing the boundaries on specific energy is the name of the game, all of these developers are designing electric/hybrid/UAM today on the premise that the business case depends on significantly better batteries being available in a few years, about the time these things are certified and ready to take off.

Bleeding edge battery tech is fundamentally incompatible with batteries which don't catch on fire

If they push the envelope too hard on that they are going to set themselves back by a couple decades when flaming electric planes full of flaming, screaming pax start falling out of the sky.

Airbus is currently working with SAS on a hybrid electric aircraft...
