Summary:A flexible electrode assembly with a reinforcement structure using expandable metal according to the present invention includes: a plurality of electrode plates (110) arranged on both sides thereof while interposing a separator; an electrode mixture material (120) applied on the plurality of electrode plates (110); and an expandable metal layer (140) coupled on the plurality of electrode plates (110). The expandable metal layer (140) is stacked on a pair of electrode plates (110) forming the outermost parts of both sides of the flexible electrode assembly among the plurality of electrode plates (110) with an adding method or the expandable metal layer (140) is welded on a tab for connecting an electrode lead, a tab for parallel connection, or the tab for connecting an electrode lead and the tab for parallel connection. Accordingly, the present invention can implement stable performance by maintaining an electrochemical characteristic. 본 발명에 따라 확장형 금속을 이용한 보강 구조를 갖는 플렉서블 전극 조립체는 분리막을 사이에 두고 양측에 배치되는 복수의 전극판(110); 상기 복수의 전극판(110) 상에 도포되는 전극 합재(120); 및 상기 복수의 전극판(110) 상에 결합되는 확장형 금속층(140);을 포함하고, 상기 확장형 금속층(140)은, 상기 복수의 전극판(110) 중 상기 플렉서블 전극 조립체의 양측 최외곽을 이루는 한 쌍의 전극판(110) 상에 덧댐 방식으로 적층되거나, 상기 확장형 금속층(140)은 상기 전극판(110)을 구성하는 전극 리드 연결용 탭 또는 병렬 연결용 탭 또는 전극 리드 연결용 탭 및 병렬 연결용 탭 상에 용착된다.
