Abstract
(EN)
A secondary battery capable of preventing a deformation is disclosed. In one embodiment, disclosed is a secondary battery comprising: an electrode assembly in which a first electrode plate having a first non-coated part protruding in a first direction, a second electrode plate having a second non-coated part protruding in a second direction that is opposite to the first direction, and a separator interposed between the first electrode plate and the second electrode plate, are wound so that the first non-coated part and the second non-coated part are exposed in opposite directions; a first current collecting plate electrically coupled to the first non-coated part; a second current collecting plate electrically coupled to the second non-coated part, and having an end part protruding farther toward the outside of the first current collecting plate by penetrating the winding center of the electrode assembly; and an insulation member positioned between the end part of the second current collecting plate and the first current collecting plate, wherein the end part of the second current collecting plate is coupled with the insulation member by pressing the insulation member from the outside thereof.
