Abstract
A lithium ion secondary battery and a jelly-roll type electrode assembly in a lithium ion secondary battery including a can and a cap assembly together with the electrode assembly. The electrode assembly is made up of two electrodes; a ceramic separator coating on at least one surface among the four surfaces of the two electrode plates and located between the two opposing electrodes; and porous polymer resin separation films placed between the electrode plates at certain locations where the plates are bent to relatively small radii of curvature and outward from an innermost portion of a core, and/or at terminal ends of the electrode plates, respectively.
