Abstract
An electrode assembly may have improved rigidity by including a structure in which a negative electrode having separators disposed on both surfaces thereof is bent in a zigzag shape, and a plurality of positive electrodes are individually inserted inside separators bent together with the negative electrode, thereby realizing high safety of the battery. Further, the electrode assembly of the present invention may prevent an end portion of an inserted positive electrode from being exposed by realizing a variation between a separation distance of an end portion of any positive electrode and a separation distance of an end portion of a positive electrode adjacent to the positive electrode with respect to a side surface including the bent structure of the negative electrode at a predetermined ratio, so that the safety and energy density of the battery can be improved.
