Abstract:
1. A secondary battery, comprising: an electrode assembly including a first electrode, a second electrode, a separator interposed between the first electrode and the second electrode for insulating the first electrode and the second electrode from each other, a first electrode tab extending from one side of the first electrode, and a second electrode tab extending from one side of the second electrode; and a pouch including a body and a cover, wherein the body of the pouch includes a receiving part for accommodating the electrode assembly, and a body sealing part extending from the receiving part, wherein the cover of the pouch includes a covering part corresponding to the receiving part of the body, and a cover sealing part corresponding to the body sealing part, wherein the body comprises at least two insulation layers and a conductive layer interposed between said at least two insulation layers and the cover comprises at least two insulation layers and a conductive layer interposed between said at least two insulation layers, wherein the first electrode tab and the second electrode tab are electrically connected to the conductive layers of the body and the cover, respectively, of the pouch, wherein the conductive layer of the body is electrically insulated from the conductive layer of the cover, and wherein the body includes a first tab contact portion exposing the first conductive layer formed at one surface of the body and a first external contact portion exposing the first conductive layer at another surface of the body.
