OverviewHistoryOperating principleMaterialsComparisonRecent R&DCommercialization and pricesElectric vehicles
A sodium-ion battery (NIB, SIB, or Na-ion battery) is a rechargeable battery that uses sodium ions (Na ) as charge carriers. In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, simply replacing lithium with sodium as the intercalating ion. Sodium belongs to the same group in the periodic table as lithium and thus has similar chemical properties. H
