Sodium Ferric Sulfate

Sodium ferric sulfate is a polyanionic cathode material for sodium ion batteries, with the characteristics of low cost, high reversible capacity, high operating voltage, and excellent long-term cycle performance. Due to the strong induction effect of sulfate ions, its Fe³⁺ /Fe²⁺ redox potential is the highest among existing cathode materials, which partially makes up for its low energy density. In addition, the three-dimensional skeleton structure of sodium ferric sulfate remains stable during the migration of sodium ions, which is very suitable for repeated charge and discharge cycles.
