Prussian blue (PB) has great potential for use as a sodium cathode material owing to its high working potential and cube frame structure. Herein, this work reports a two-step method to synthesize PB with ascorbic acid as the ball-milling additive, which improves the electrochemical rate performance of PB during the traditional co-precipitation method. The obtained PB sample exhibited a superior specific capability (113.3 mAh g −1 even at 20 C, 1 C = 170 mA g −1 ) and a specific capacity retention of 84.8% after 100 cycles at 1 C rate. In order to enhance the cycling performance of the PB, an in situ polyaniline coating strategy was employed in which aniline was added into the electrolyte and polymerized under electrochemical conditions. The coated anode exhibited a high specific capacity retention of 62.7% after 500 cycles, which is significantly higher than that of the non-coated sample, which only remains 40.1% after 500 cycles. This development has shown a great potential as a low-cost, high-performance and environment-friendly technology for large-scale industrial application of PB.

Prussian blue analogues (PBAs) have gained tremendous attention as promising low‐cost electrochemically‐tunable electrode materials, which can accommodate large Na+ ions with attractive specific capacity and charge‐discharge kinetics. However, poor cycling stability caused by lattice strain and volume change remains to be improved. Herein, metal‐doping strategy has been demonstrated in FeNiHCF, Na1.40Fe0.90Ni0.10[Fe(CN)6]0.85·1.3H2O, delivering a capacity as high as 148 mAh g‒1 at 10 mA g‒1. At an exceptionally high rate of 25.6 A g‒1, a reversible capacity of ~55 mAh g‒1 still can be obtained with a very small capacity decay rate of 0.02% per cycle for 1000 cycles, considered one of the best among all metal‐doped PBAs. This exhibits the stabilizing effect of Ni doping which enhances structural stability and long‐term cyclability. In situ synchrotron X‐ray diffraction reveals an extremely small (~1%) change in unit cell parameters. The Ni substitution is found to increase the electronic conductivity and redox activity, especially at the low‐spin (LS) Fe center due to inductive effect. This larger capacity contribution from LS Fe2+C6/Fe3+C6 redox couple is responsible for stable high‐rate capability of FeNiHCF. The insight gained in this work may pave the way for the design of other high‐performance electrode materials for sustainable sodium‐ion batteries.
