    Yup. Studies on sodium batteries has been going on for years. If they finally achieve good enough state this is big since lithium is limited and expensive while sodium is everywhere. However sodium batteries will never be effective as lithium batteries because of the atom size. Lithium is much smaller than sodium.

      True, but this is solid state so it may be higher density than current Lithium based batteries. But it might not beat a hypothetical lithium solid state battery. On the other hand, sodium batteries today beat out lithium in many other ways than capacity, and if those things are true for solid state then as long as there is a big enough jump in capacity due to the solid state transition then I think sodium is going to be the go-to for most uses in the future.

        Don’t actually know about density differences but I’m quite positive that sodium batteries will be used in many sectors because it will be much cheaper. Probably not on cars, maybe not on phones as well. It will be enough for all other small appliances I think.
