Prussian white, a derivative of Prussian blue also known as Berlin white or Everett’s salt. It’s a structural material composed of sodium, iron, carbon, and nitrogen which are chemically associated with the dye Prussian blue. The white color is due to the high levels of sodium as it’s a fully reduced and sodiated form of Prussian blue. It’s primarily used as positive electrode material in sodium-ion batteries as the large pores help in the storage and capturing of various atoms & molecules.
Synonyms: Berlin White, Everett’s salt

Prussian Blue is a deep blue pigment, while Prussian White is a white powder. Both are iron-based compounds, but Prussian White is a sodium-rich form of Prussian Blue. While Prussian Blue is well-known, Prussian White is gaining attention for its potential in energy storage, particularly in sodium-ion batteries.
Prussian White, also known as Berlin White or Everett’s Salt, is a white powder that is a sodium-rich form of Prussian Blue. It’s composed of sodium, iron, carbon, and nitrogen. This compound is gaining significant attention for its potential as a cathode material in sodium-ion batteries due to its low cost, non-toxicity, and high energy density.
The theoretical capacity of Prussian White (Na2Fe[Fe(CN)6]) is approximately 170 mAh/g. This high capacity, coupled with its low cost and non-toxicity, makes it a promising cathode material for sodium-ion batteries.
