This seems like a pretty big deal, right?
Indeed, the fact that they filed a patent is also an indicator that this is not purely an experiment, but a tangible way forward. Let’s hope this can scale up quickly.
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.
