Abstract
一种二次电池，该二次电池包括电极组件(31)、第一端子(11)和第二端子(21)以及顶盖片(41)，电极组件(31)包括第一极片和第二极片，第一端子(11)与第一极片电连接，第二端子(21)与第二极片电连接，二次电池还包括：第一电阻构件(18)、第二电阻构件(24)、附接于第一端子(11)的接触片(12)、与第二端子(21)电连接的导电片(22)，顶盖片(41)通过第一电阻构件(18)始终与第一端子(11)电连接，且顶盖片(41)与第二端子(21)以及导电片(22)绝缘设置，当二次电池的内部压力超过基准压力时，接触片(12)与导电片(22)接触，以形成通过第一极片、第一端子(11)、接触片(12)、导电片(22)、第二端子(21)以及第二极片的电连接路径，第二电阻构件(24)串联于该路径中，第一电阻构件(18)的阻值大于第二电阻构件(24)的阻值。该方案对二次电池实现了两方面的保护，提高了二次电池的安全性。
