![]() A downside of the larger ionic radius of Na + is a slower intercalation kinetics of sodium-ion electrode materials. Similar ionic radii of lithium and iron result in their mixing in the cathode material during battery cycling, and a resultant loss of cyclable charge. This is because the ionic radius of Na + (116 pm) is substantially larger than that of Fe 2+ and Fe 3+ (69–92 pm depending on the spin state), whereas the ionic radius of Li + is similar (90 pm). Another factor is that cobalt, copper and nickel are not required for many types of sodium-ion batteries, and more abundant iron-based materials (such as NaFeO2 with the Fe3+/Fe4+ redox pair) work well in Na+ batteries. An obvious advantage of sodium is its natural abundance, particularly in saltwater. SIBs received academic and commercial interest in the 2010s and early 2020s, largely due to the uneven geographic distribution, high environmental impact, and high cost of lithium. ![]() Although, in some cases (such as aqueous Na-ion batteries) they are quite different from Li-ion batteries. Sodium belongs to the same group in the periodic table as lithium and thus has similar chemical properties. ![]() In some cases, its working principle and cell construction are similar to those of lithium-ion battery (LIB) types, but it replaces lithium with sodium as the intercalating ion. Sodium-ion batteries ( NIBs, SIBs, or Na-ion batteries) are several types of rechargeable batteries, which use sodium ions (Na +) as its charge carriers.
