An electrode assembly including a first electrode plate and a second electrode plate whereon first and second electrode active materials, and first and second electrode tabs are formed, respectively, and including a separator disposed between the first electrode plate and the second electrode plate while overlapping with the first electrode plate and the second electrode plate; and a planarizing member disposed on at least one of first and second ends that are opposite to each other in a longitudmal direction of the electrode assembly, wherein the planarizing member covers a stepped surface exposed on the at least one of the first and second ends so as to planarize the stepped surface. Damage of the electrode assembly due to a stepped surface, and an internal short between positive and negative electrodes, may be prevented. |
