이차 전지가 제공된다. 상기 이차 전지는 외장체(11); 상기 외장체의 내부에 수납되고, 부극(22) 및 정극(21)을 구비한 전극 구조체(20); 상기 외장체의 내부에 수납된 전해액; 및 상기 외장체의 내압에 따라서 전류를 차단하도록 구성된 안전 밸브 기구(15)를 구비하며, 여기서 상기 비함침 전해액 중 적어도 1종은 상기 안전 밸브 기구의 작동 확률을 증가시키도록 하는 양이고, 상기 부극은 상기 안전 밸브 기구의 작동 확률을 증가시키도록 하는 부극 전위에서 전기화학적으로 가스를 발생시키는 재료를 포함한다.

    A secondary battery is provided. The secondary battery includes an outer package (11); an electrode structure (20) contained inside the outer package, wherein the electrode structure includes an anode (22) and a cathode (21); an electrolytic solution contained inside the outer package, and a safety valve mechanism (15) configured to interrupt a current in accordance with an internal pressure of the outer package, wherein at least one of the non-impregnation electrolytic solution is in an amount so as to increase an operation probability of the safety valve mechanism and the anode includes a material that electrochemically generates gas at an anode potential so as to increase an operation probability of the safety valve mechanism.
