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.
> We have existing lithium ion cell chemistries that allow 350-500 mile electric car range
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.
