The rocking-chair aqueous proton battery utilizes dipyridophenazine and indium hexacyanoferrate as anode and cathode materials, achieving 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.
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.
