Abstract

The pre-intercalation of Na⁺ ions in layered birnessite-MnO₂ 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–MnO₂ nanoflakes compared to the MnO₂ nanorods.
