Sodium is a soft, silvery coloured metal which, like other members of the alkali group of metals, is extremely reactive. As for the other members of the group, it can be prepared by electrolysis of the fused halide or hydroxide. Along with potassium, it is one of the more common alkali metals, there being 28300 ppm in the earth’s crust, primarily as the carbonate, chloride or nitrate.
Sodium-Ion Battery
Sodium-ion batteries operate analogously to lithium-ion batteries, with both chemistries relying on the intercalation of ions between host structures. In addition, sodium based cell construction is almost identical with those of the commercially widespread lithium-ion battery types.
