Abstract

Abstract : A high-performance aqueous proton battery is fabricated by pairing a dipyridophenazine anode with an indium hexacyanoferrate cathode in a pure H2 SO4 electrolyte. Abstract : A rocking-chair aqueous proton battery is assembled by using dipyridophenazine and indium hexacyanoferrate as the anode and cathode materials, respectively. The reversible amination of redox-active phenazine moieties in dipyridophenazine and fast intercalation–deintercalation of protons in hexacyanoferrate enable the aqueous proton battery to achieve a reversible specific capacity of 37 mA h g −1 at 1 A g −1, good cycling stability with 76.1% capacity retention over 3000 cycles and excellent rate capability.
