      Those are not “better” batteries chemically or electrically. They are just cheaper and don’t use lithium which is considered a feature.

        Sodium batteries are cheaper, safer, and last longer than lithium batteries. That’s exactly what you want for grid-scale energy storage. So yes, sodium IS better than lithium for grid-scale energy storage

          Cheap, high longevity, high capacity. You can’t have all three.

          What’s better depends on application. I don’t want a cheap battery in my car if I only get 80 miles on a charge.

            Go reread the thread. You’re (hopefully unintentionally) arguing against using sodium batteries for grid storage because lithuim has more energy density.

            Cost, high longevity, and heat tolerance are way more important for grid storage than energy density. Sodium batteries are perfect for that, and were poised to start being supplied for that application until the price of lithium tanked at the start of the year.

            Also, the sodium batteries that are (and were) about to go to market have enough energy density that manufacturers were considering adding them to cars by mixing and matching sodium and lithium cells in varying ratios to match various use cases. The two chemistries aren’t mutually exclusive in any field

      That’s great for grid storage. Maybe one day for even EV use, emphasis on maybe. But you’ll never have a cell phone with a sodium battery
