Abstract:
In the preparation of Prussian blue analogs (PBAs), Na+ loss and Fe2+ 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 Fe2+ oxidation. As the cathode of sodium-ion batteries, it exhibited excellent electrochemical performance.
