The present invention relates to an electrode assembly for a secondary battery and a lithium secondary battery comprising same, and more specifically, to an electrode assembly comprising an anode, a cathode, and a separation membrane, and a lithium secondary battery comprising same, wherein the anode comprises as an anode active material a lithium cobalt oxide and a lithium nickel complex oxide, which is reacted with a polymer containing fluoride and then provided with a coating layer on the surface thereof, wherein the cathode comprises as a cathode active material carbon and a silicon oxide, wherein the operating voltage range is between 2.50V to 4.35V, and wherein the anode active material has a high rolling density due to a bimodal form in which the average particle size of the cobalt oxide and the average particle size of a lithium nickel complex oxide are different from each other. Also, the present invention relates to an electrode assembly in which alumina (Al2O3) is coated on the ...
