Sodium-ion battery

Uncommon card · No. 83594

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, but different in that the battery is manufactured with sodium instead of lithium as the intercalating ion. Sodium belongs to the same group in the periodic table as lithium and thus has similar chemical properties; the term 'SIB' likewise describes a family of different chemistries. However, designs such as aqueous batteries are quite different from LIBs. SIBs received academic and commercial interest in the 2010s and early 2020s, largely due to lithium's high cost, uneven geographic distribution, and environmentally damaging extraction process. Unlike lithium, sodium is abundant, particularly in saltwater. Further, cobalt, copper, and nickel are not required for many types of sodium-ion batteries as they are in Lithium batteries, and abundant iron...
