High Performance MnO2 Nanoflower Electrode and the Relationship Between Solvated ion Size and Specific Capacitance in Highly Conductive Electrolytes

Flower shaped birnessite type manganese oxide (δ-MnO2) nanostructures are synthesized using a simple hydrothermal process with an aim to fabricate high performance supercapacitors for energy storage electrode. The studies reveal that layered δ-MnO2 had a basal plane spacing of ∼0.73 nm and are compo...
