  • Electrode assembly and secondary battery using the same
    Patent number: 8283064
    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 Y1=tensile strength×thickness of finishing tape/modulus of elasticity, with Y1 ranging from 64 to 89. Alternatively, the finishing tape includes a film layer and an adhesive layer, and satisfies the equation Y2=tensile strength×thickness of film layer of finishing tape/modulus of elasticity, with Y2 ranging from 51 to 75. The finishing tape effectively prevents an increase in the thickness of a high-capacity secondary battery.
