Doubling of electrochemical parameters via the pre-intercalation of Na super(+) in layered MnO sub(2) nanoflakes compared to alpha -MnO sub(2) nanorods

The pre-intercalation of Na super(+) ions in layered birnessite-MnO sub(2) is shown to have a dramatic influence on its electrochemical properties. Electrochemical studies showed the doubling of the specific capacitance and energy density in the layered Na-MnO sub(2) nanoflakes compared to the MnO s...

Zusammenfassung:The pre-intercalation of Na super(+) ions in layered birnessite-MnO sub(2) is shown to have a dramatic influence on its electrochemical properties. Electrochemical studies showed the doubling of the specific capacitance and energy density in the layered Na-MnO sub(2) nanoflakes compared to the MnO sub(2) nanorods.
