It's unlikely you will see a car powered by those in near future if ever as they have relatively low density. But you'll definitely see those as home battery and such where size/density doesn't matter that much. And I bet it's less inflammable as well.
Edit: ha, I stand corrected, there are cars powered by these but don't expect huge range.
I don't think there are plenty of dogfights in this era. Airplanes are mostly used for dropping bombs and rockets against ground targets from a safe distance and shooting down cruise missiles and drones.
