In addition to the article’s stated benefits of faster charging than Li-ion, less temperature sensitivity, and lower propensity of thermal runaway, does switching to sodium also potentially address a raw materials problem? (Imagine if desalination could be made ecologically viable by harvesting the waste sodium for batteries…)
And what’s the downside? More complex chemistry to make the cathode?
