If the id4 on sale now has enough range for you, then a sodium ion version will give the same while being cheaper and having fewer fire concerns. Solid state lithium will be nice, but expect them in more expensive models.
I have such an ev right now that’s in line with the numbers we’re talking about here. It’s good enough for a road trip. We’re trying to sell our only ICE car now because we’re not using it.
Volkswagen id4 today has a battery of 168 wh/kg:

CATL launched a 160 wh/kg sodium battery in 2021:

They are already gearing up for production of 200 wh/kg sodium batteries, and in talks with automakers about it:

Even if they manage to “gear up” and make it to 200 wh/kg, that’s years away and TODAY lithium EV batts are hitting 270 wh/kg. 35% more energy dense.
And you’ll spend more money to get that. Not every EV needs the most capacity out there.
If your ev isn’t good enough for a road trip, that means for like 90% of you, you have to own another vehicle.
