A method of manganese dioxide electrode supercapacitor prepared

Preparing one kind of manganese dioxide electrode for supercapacitor. Wherein the electrode preparation process includes the following steps: first electrode collector surface layer of co-deposited manganese alloy coating by electrochemical; and the resulting band manganese alloy coating electrodes anodized to give manganese dioxide electrode. The present invention is realized by electrochemical co-deposition of a uniform distribution of alloying elements in the internal electrode prepared to increase its electronic conductivity and electrochemical anodization process; by anodic oxidation on the one hand the manganese alloy layer is converted to an electrical manganese dioxide material is chemically active, but also to build on the electrode surface and the prepared internal pore structure, thereby increasing the solid phase mass transfer and electrochemical properties of reactive material to obtain high specific capacitance characteristics of electrodes.
