Per RichA:
You'll be waiting a LONG time for that. Transportation services already hate lithium.

Because of the fire hazard, right?

My takeaway from reading about metallic is that, besides doubling the
power-to-weight ration, it eliminates the fire hazard... something about the
solid plastic electrolyte... specifics are above my pay grade, but it seemed
pretty sure that the fire hazard goes away.
