ELECTRODE ASSEMBLY AND MANUFACTURING METHOD OF THE SAME

An electrode assembly includes a positive electrode member including a positive electrode current collector and a positive electrode active material coating layer formed on the positive electrode current collector; and a negative electrode member including a negative electrode current collector and a negative active material coating layer formed on the negative electrode current collector, wherein the positive electrode current collector comprises a disk-shaped positive electrode disk part, and a cylindrical-shaped positive electrode cylinder part extended from one surface of the positive electrode disk part, wherein the negative electrode current collector comprises a disk-shaped negative electrode disk part, and a cylindrical-shaped negative electrode cylinder part extended from one surface of the negative electrode disk part, and wherein the positive electrode member and the negative electrode member are assembled so that the positive electrode cylinder part and the negative electrode cylinder part are adjacent to each other.
