## Description

- description: We successfully synthesized Co-substituted MnO2 nanosheets with a composition
    of Mn1－xCoxO2 (x = 0.2－0.5) by exfoliating the protonated form of Na0.6Mn1－xCoxO2
    and studied the electrochemical properties of the exfoliated Mn1－xCoxO2 nanosheets.
    Protonation can be achieved along with the preservation of the chemical composition
    of the host layers of the starting material. We clarified different charge compensation
    mechanisms against cobalt doping in the two different systems, Na-Mn1－xCoxO2 and
    H-Mn1－xCoxO2. The ratio of Mn to Co did not change upon exfoliation, yielding
    Mn1－xCoxO2 nanosheets. The obtained nanosheets showed improved cycle performance
    compared to MnO2 nanosheets, making them favorable for applications such as energy-storage
    devices.
