Abstract
An electrode assembly of a secondary battery includes an electrode group including a first electrode plate, a separator, and a second electrode plate that are stacked and wound, and a finishing tape attached to a predetermined region of a terminal portion of the electrode group. The finishing tape satisfies the equation Y=tensile strength×thickness of finishing tape/modulus of elasticity, with Yranging from 64 to 89. Alternatively, the finishing tape includes a film layer and an adhesive layer, and satisfies the equation Y=tensile strength×thickness of film layer of finishing tape/modulus of elasticity, with Yranging from 51 to 75. The finishing tape effectively prevents an increase in the thickness of a high-capacity secondary battery.
