Electrode Lead, Method For Producing Same, And Pouch Type Secondary Battery

Abstract: An electrode lead according to an embodiment of the present invention for addressing the problem includes: a first electrode lead having one end connected to an electrode tab protruding from one side of an electrode assembly; a second electrode lead having one end connected to the other end of the first electrode lead and the other end protruding to the outside of a battery case accommodating the electrode assembly; and a connection part that connects the first electrode lead and the second electrode lead to each other. The connection part is formed by curing an adhesive applied between the first electrode lead and the second electrode lead, wherein the adhesive is formed by mixing a conductive material and a solvent. The solvent is formed by mixing a polymer and a diluent and includes 5 wt% to 15 wt% of the diluent.
