    Why not? From what I’ve seen, they’re about 75% as energy dense as lithium, and a lot cheaper. So if the Chevy Bolt gets 200-250 miles range on lithium batteries, I’d expect 150+ miles w/ sodium-ion, which is plenty for my commute. If the battery costs half as much and lasts 5-10 years, I’d buy that to replace my commuter in a heartbeat. Give me a commuter at $15-20k w/ 150 miles range and I’ll buy.

      these batteries are a lot cheaper, and a lot more cycle resistant, which is what you primarily do for stationary storage, i think they’re probably safer as well?

      It would make some EVs cheaper, but they would have less range, and it’s probably a little redundant considering you could just use less lithium ion batts instead.

      Like the commenter said, we should be focusing on the solid state batts that samsung is fucking with, those are have REAL potential to be significantly better for EVs.

        A solid state battery would likely be able to replace my family car, but I don’t need that for a commuter, I just need the battery to be cheaply replaceable and enough range to get to work and back. I think we should be looking at both options.

          i mean sure, personally i doubt it’ll happen, im assuming they’re focusing on developing better battery tech first and foremost, though im guessing sodium ions would probably make their way into EVs eventually.

            They already are… in China. I’m saying we should do that here in the US. We have the battery plant, so let’s put them in some inexpensive cars to replace commuters.

              i dont think we’ve even broken ground on a sodium ion plant let alone making and production testing batteries for the market to begin with. I’ve got nothing aginst it, and EV manufacturers are probably going to do it, but whatever

              Also you can buy a used prius for pretty cheap? The batteries aren’t that expensive to replace if they go bad/are bad.

                Yup, and I currently drive a Prius. I’m looking at used Bolts ($13-15k used), but I’m a little worried about fire risk (it’ll be parked in my attached garage) and battery repair is going to be super expensive. A new sodium ion EV that’s much cheaper (say, $15-20k) would be attractive, but I’m definitely not paying >$30k for a commuter.

      Explain that to the average car buyer who sees the lower number and rules it out.

        If they also see a lower price, they’ll be more interested.

        And this doesn’t need to appeal to every car buyer, there’s a market for budget-friendly cars with a narrow use-case. 150 miles is plenty for a second car, and would probably not appeal to people looking for a primary car, whereas 250 miles kind of bridges that gap. Segment the market and it should do well.
