Patent ID: 8283064

Claim:
An electrode assembly comprising: an electrode group comprising a first electrode plate, a separator, and a second electrode plate that are sequentially stacked and wound; and a finishing tape attached to a predetermined region of a terminal portion of the electrode group; wherein the finishing tape satisfies the following equation, with Y 1 ranging from 64 to 89 when a tensile strength of the finishing tape is expressed in kgf/cm 2 , a thickness of the finishing tape is expressed in μm, and a modulus of elasticity of the finishing tape is expressed in kgf/mm 2 : Y ⁢ ⁢ 1 = tensile ⁢ ⁢ strength × thickness ⁢ ⁢ of ⁢ ⁢ finishing ⁢ ⁢ tape modulus ⁢ ⁢ of ⁢ ⁢ elasticity .
