Abstract
一种二次电池的顶盖组件(100)以及二次电池。二次电池的顶盖组件(100)包括：顶盖板(10)；第一电极端子，包括端子板(31)，端子板(31)设置在顶盖板(10)的一侧并与顶盖板(10)绝缘；第二电极端子，第二电极端子与顶盖板(10)电连接；导电件(35)，导电件(35)与端子板(31)位于顶盖板(10)的同一侧，导电件(35)与顶盖板(10)电连接并与端子板(31)绝缘，以及翻转片(36)，翻转片(36)附接于端子板(31)，并且翻转片(36)被构造为当二次电池内部的压力超过预定值时翻转，以使翻转片(36)与导电件(35)电连接。能够在二次电池内部压力升高至超过基准压力时，将第一极片和第二极片短路，避免在壳体内部的压力升高时，由于壳体发生形变而对设置在顶盖组件(100)上的翻转片(36)造成拉应力，能够使翻转片(36)维持在预定翻转压力。
