Aluminum air batteries are also worse than lithium air batteries.
We have existing lithium ion cell chemistries that allow 350-500 mile electric car range and battery lifetimes well into 500,000 miles, possibly millions of miles.
This one is. Cheaper, safer, better power density, long cycle life. It has a wide temperature tolerance so may not need much temperature management when in an EV battery pack:

Their batteries are at 1.7 volts currently. They say they can achieve the same voltages as current lithium-ion batteries to be a direct replacement for them.

Few EVs achieve that. Why? Because the batteries cost too much and weigh too much leading to a more expensive vehicle. Not everyone is going to buy a Lucid Air:
We need cheaper batteries, like this aluminium-ion battery.
Not really for cars. For cars they still need to become cheaper, safer, lighter, more sustainable, more recyclable, better energy density for more range, better power density for recuperation and faster charging, and more cycles for greater life span.
This aluminium-ion battery looks interesting:

The power density and duty cycles are there. They say the energy density is there once they increase the cell voltage.
