Lithium air, while possible to yield fantastic energy densities, seems unlikely to bare useful fruit to EV's inside the next decade.
I would love to be wrong about this, but everything I've seen with respect to Lithium air testing and/or other cell designs using metallic Lithium anodes seem a long ways off from being useful outside entertaining lab techs with unexpected and occasionally exciting displays during cycling.
While it may be possible for these challenges to be solved by some clever additive or yet-untested electrolyte blend, I would not recommend holding your breath.
The good news is, EV's don't need the crazy level of energy density that is possible to achieve with Lithium Air.
Each carcinogen vapor exposure includes a dice roll for cancer.
Each mutagen vapor exposure includes a dice roll for reproductive genetic defects in your children.
Each engine start sprays them into a shared atmosphere which includes beings not offered an opportunity to consent accepting these cancer experiences and defective genetics life experiences.
