    • 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.

    • Disclosed are an anode active material, a non-aqueous lithium secondary battery, and a preparation method thereof. The surface of a carbonaceous material is modified without using an electrolyte additive, and the reactivity and structural stability of the surface is improved, thereby obtaining long lifetime characteristics without deteriorating charge/discharge efficiency and rate characteristics when applied as an anode active material of a non-aqueous lithium secondary battery. The anode active material comprises a carbonaceous material, and a coating layer formed on the surface of the carbonaceous material through hetero atom substitution, wherein the hetero atom can be phosphorus (P) or sulfur (S). A side reaction with an electrolyte on the surface of the carbonaceous material is inhibited and the structural stability of the surface is enhanced by forming a coating layer on the surface of the carbonaceous material with a hetero atom such as phosphorus (P) or sulfur (S).
