Abstract
Disclosed are a composite electrode active material and a supercapacitor using the same, and more particularly, an electrode active material having MRuO(M=Sr, Ba, Mg) and a supercapacitor using the same, wherein the electrode active material is characterized by comprising MRuO, where M is at least one selected from a group consisting of strontium, barium and magnesium, and a method for fabricating a composite electrode active material comprises (a) preparing a spinning solution containing a precursor of M oxide, a precursor of Ru oxide, a polymer and a solvent, (b) spinning the spinning solution on a collector to fabricate a nanofiber web having MRuOprecursor, and (c) performing heat treatment for the nanofiber web to remove the polymer so as to make an electrode active material in the structure of porous nanofiber web having MRuO, wherein the M comprises at least one selected from a group consisting of strontium, barium and magnesium.
