MSE PRO™ Sodium Ferric Sulfate (Na2+2xFe2-x(SO4)3, -0.1≤x≤0.4) NFS Cathode Powder for Sodium Ion Batteries
Sodium Ferric Sulfate (Na2+2xFe2-x(SO4)3, -0.1≤x≤0.4) NFS is a poly-anionic cathode material used in sodium-ion batteries, known for its abundant crustal reserves, low cost, high working voltage, and excellent long-term cycling performance. Thanks to the strong induction effect of sulfate ions, it exhibits the highest Fe3+/Fe2+ redox potential among existing cathode materials, partially compensating for the low energy density. Additionally the three-dimensional framework structure of sodium iron sulfate maintains stability during sodium ion migration, resulting in good cycling performance. As a result, it is primarily applied in the fields of electric bicycles, tricycles, low-speed vehicles, and energy storage.
