Graphite/DSA assembled electrode for redox flow battery, method of manufacturing the same and redox flow battery including the same

Abstract

Disclosed is a graphite/DSA assembled electrode for a redox flow battery, obtained by assembling a graphite electrode made of micro-sized graphite and a DSA electrode using rolling thus improving cell performance including electrode durability, corrosion resistance, power density, energy efficiency and cycle properties. A method of manufacturing the graphite/DSA assembled electrode is also provided, which includes preparing a mixture composed of a graphite active material, a conductive material and a binder into a slurry using an alcohol, evaporating the alcohol from the slurry thus preparing a paste, thinly spreading the paste into an electrode sheet, and rolling the electrode sheet along with a DSA electrode thus obtaining the assembled electrode. A redox flow battery including the electrode thus obtained is also provided, which has increased electrode durability and corrosion resistance and enhanced power properties, energy efficiency and cycle performance.
