Herein, vanadium hexacyanoferrate (V/Fe PBA) is proposed as a breakthrough to this limitation, and its electrochemical performance as a cathode for aqueous rechargeable batteries (ARBs) is investigated for the first time. V/Fe PBAs are synthesized by a simple co-precipitation method with optimization of the acidity and molar ratios of precursor solutions. The V/Fe PBAs provide an improved capacity of 91 mA h(-1) under a current density of 110 mA g(-1) (C-rate of approximate to 1.2 C), taking advantage of the multiple-electron redox reactions of V and Fe ions. Under an extremely fast charge/discharge rate of 3520 mA g(-1), the V/Fe PBA exhibits a sufficiently high discharge capacity of 54 mA h g(-1) due to its opened structure and 3D hydrogen bonding networks. V/Fe PBA-based ARBs are the most promising candidates for large-scale stationary energy storage systems due to their high electrochemical performance, reasonable cost, and high efficiency.
