Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Sure, but those are unlikely to be used in cars any time soon, if ever.
They are already in production.

I've heard that Sodium batteries have huge voltage difference full vs. empty. Some sources state the discharge graph is almost linear line in capacitors. Is means, if true, sodium batteries need completely different frequency converter (inverter) design.
And LiFePO4 production seem to have ramped up so much that sodium is still pricier... although, if CATL has enough commitment to continuously produce sodium... tables can turn.
Oh shit that's dope. I had no idea. Looks like they're on the lower end of range (less than 300miles at best) but expect to make up for it in extreme weather handling.
Specifically, this car has an expected cell energy density of up to 175 Wh/kg while lithium batteries are usually around 150-300 wh/kg. That's a lot more comparable than I had thought they were.
