Potentiodynamical co-deposited manganese oxide/carbon composite for high capacitance electrochemical capacitors

Manganese oxide/carbon composite materials were prepared by introducing the carbon powders into the potentiodynamical anodic co-deposited manganese oxide in 0.5 mol L − 1 MnSO 4 and 0.5 mol L − 1 H 2SO 4 mixed solution at 40 °C. The surface morphology and structure of the composite material were exa...
