The proton storage in rechargeable aqueous zinc‐ion batteries (ZIBs) are attracting extensive attention due to the fast kinetics of H + insertion/extraction. However, up to now, it is not achieved in organic materials‐based ZIBs with a mild electrolyte. Herein, we developed aqueous ZIBs based on diquinoxalino [2,3‐ a :2',3'‐ c ] phenazine (HATN) in a mild electrolyte. Electrochemical and structural analysis confirm for the first time that such Zn/HATN batteries experience a H + uptake/removal behavior with highly reversible structural evolution of HATN. The H + uptake/removal endows the Zn/HATN batteries with enhanced electrochemical performance. Proton insertion chemistry will broaden the horizons of aqueous Zn/organic batteries and open up new opportunities to construct high‐performance ZIBs.
