Abstract Sodium-ion batteries (NIBs) are increasingly becoming commercially viable alternatives to lithium-ion batteries (LIBs), driven by sodium''s lower cost and greater resource availability.
Energy storage technologies, including batteries, are crucial for improving the flexibility of power systems while maintaining grid stability. Their importance will continue to grow as the share of renewables in
Much of the attraction to sodium (Na) batteries as candidates for large-scale energy storage stems from the fact that as the sixth most abundant element in the Earth''s crust and the fourth most abundant
While sodium-ion batteries are not yet ready to replace lithium-ion for long-range EVs due to lower energy density, several companies (e.g., CATL, Faradion) are exploring sodium-ion for
As such, sodium-ion batteries (NIBs) have been touted as an attractive storage technology due to their elemental abundance, promising electrochemical performance and
While sodium-ion batteries have lower energy density than lithium-ion batteries, they provide a sustainable and cost-effective energy storage solution for specific applications such as grid
Further, cobalt, copper, and nickel are not required for many types of sodium-ion batteries, and abundant iron -based materials (such as NaFeO. 2 with the redox pair) [3] work well in batteries.
While efforts are still needed to enhance the energy and power density as well as the cycle life of Na-ion batteries to replace Li-ion batteries, these energy storage devices present significant advantages in
Increases in the energy density of sodium-ion batteries means they are now suitable for stationary energy storage and low-performance electric vehicles. The abundance of raw material for making
However, sodium-ion batteries remain particularly advantageous for stationary energy storage systems, such as solar and wind energy storage, where their lower cost and scalability excel.
