Abstract: An electrode lead for achieving the above object is provided. The electrode lead 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 configured to connect the first electrode lead to the second electrode lead, wherein the connection part is formed by a cured adhesive applied between the first electrode lead and the second electrode lead. The adhesive is formed by a mixture of a conductor and a solvent. The solvent is formed by a mixture of a polymer and a diluent. The solvent contains 5 wt % to 15 wt % of the diluent.

Abstract: To solve the above problem, a method for manufacturing an electrode lead according to an embodiment of the present invention includes: a step of manufacturing each of a first electrode lead and a second electrode lead by cutting a metal plate; a step of applying an adhesive to at least one of one end of the first electrode lead or the other end of the second electrode lead; a step of forming a lead stack by bonding the one end of the first electrode lead and the other end of the second electrode lead to each other; a step of placing the lead stack on a die; and a step of applying heat and pressure to a connection portion of the lead stack, in which the first electrode lead and the second electrode lead are connected to each other, by using a pressing device.
