Published: June 2022

In the preparation of Prussian blue analogs (PBAs), Na loss and Fe oxidation take place when washing with water. Sodium-rich PBAs were prepared with sodium ascorbate aqueous solution as the washing solution, which can suppress the Na loss and Fe oxidation. As the cathode of sodium-ion batteries, it exhibited excellent electrochemical performance.
