    The volumetric energy density is 60% of lithium ion batteries, but the energy density per kg is more like 75% since the batteries are lighter. Assuming that scales to the ev range, that’s probably sufficient for a lot of use cases.

      EVs are already too heavy and wear tires out quickly. The upcoming solid state batteries are what will go into future EVs. Samsung is producing them right now and they’re currently set to start going in higher end E vehicles in 2027. At best the sodium ion batts may be good for hybrids.

        You’re forgetting that these batteries are going to be cheap because the compounds needed are readily available. This tech is not going to replace every lithium battery out there, but it’s going to give consumers another, more economic choice vs lithium. Plus it’s a safer technology than lithium.

          They’ll be cheap, but weighing more and taking up more space is not that viable of a trade off. Except for hybrid vehicles.

      I could see it being useful for semi trucks where volume isn’t as much of an issue, especially if the batteries are hanging under the trailer.

        Too much weight. Thus far, electric semi trucks aren’t viable outside of shorter range delivery fleets.
