Sodium-Ion Batteries Enter the Mainstream: Why the Next Energy Storage Race Could Move Beyond Lithium
Sodium-ion batteries are moving rapidly from an emerging alternative to a commercially viable energy-storage technology, particularly for grid-scale, solar and residential applications. Their advantages include abundant raw materials, strong low- and high-temperature performance, reduced dependence on critical minerals and the ability to use manufacturing processes similar to lithium-ion batteries. However, sodium-ion technology is not expected to immediately replace lithium-ion across every application because energy density, manufacturing scale and supply-chain maturity remain important constraints.
