摘要： A metal oxide electrode for a supercapacitor and a manufacturing method thereof are disclosed. Potassium permanganate is absorbed on a conductive material, such as carbon or activated carbon, and mixed with a solution including manganese acetate so as to form amorphous manganese oxide. Amorphous manganese oxide powder is grounded to a powder which is mixed with binder to form an electrode having a predetermined shape. The electrode reduces equivalent serial resistance and enhances high frequency characteristics since the contact area and the adhesion strength between the manganese oxide and the conductive carbon are improved. Also, the electrode has high capacitance suitable for a supercapacitor, which is manufactured therefrom at a greatly reduced cost.
