Highlights The flower-like δ-MnO2 nanostructures with controlled oxygen vacancies as an extraordinary ZIBs cathode are innovatively developed. The cathode can present large capacity and high-rate zinc-ion storage. DFT analysis substantially unveils the effects of various vacancy concentrations on their electrochemical performances.
