Also, the secondary battery according to the present invention includes: an electrode provided with a coating portion coated with an active material on an electrode collector and a non-coating portion on which the active material is not applied to the electrode collector, the non-coating portion being adjacent to the coating portion in a width direction perpendicular to a longitudinal direction of the electrode collector, the non-coating portion having a plurality of notching tabs formed therein such that each of the plurality of notching tabs extends away from the coating portion in a width direction. When the electrode assembly is in the wound state, the plurality of notching tabs are circumferentially distributed about a central axis of the electrode assembly.",
