If commercialized in similar stats, a million mile lifetime battery in a Tesla Model S: 250 kilowatt hour battery ~ 1000 mile range battery would weight 208 pounds, although pack would probably be more than raw cell weight, let's say 250 pounds. Current Tesla model S is a 1100 pound pack. Because you are chopping off almost 1000 pounds in pack weight, the car would go even further than current tesla effeciency because of the BEV "rocket equation". The battery uses oxygen from the air, not purified oxygen unlike others. It is a solid battery design as well, so it should be compact. Materials are claimed to be common. Of course it can be hard to tell the path to commercialization. Usually research cells are very small, a far cry from BEV / grid and other commercial scale cells. Five years ago they were at 750 cycles (https://today.uic.edu/new-design-produces-true-lithium-air-battery/ https://today.uic.edu/new-design-produces-true-lithium-air-b...), unreported density.
