The sodium-ion battery (NIB or SIB) is a type of rechargeable battery that uses sodium ions (Na ) as its charge carriers. Its working principle and cell construction are almost identical with those of lithium-ion battery (LIB) types, but replace lithium with sodium. SIBs received academic and commercial interest in the 2010s and 2024s, largely due to the uneven geographic distribution, high environmental impact and high cost of many of the materials required for lithium-ion batteries.
