Abstract

本申请涉及一种电池端盖组件、二次电池、电池组及使用电池的装置，其中，端盖组件(10)用于二次电池，包括：端盖(10’)，设有用于注入电解液的通孔(11)和容纳部(12)，容纳部(12)位于端盖(10’)远离壳体(40)的一侧且沿通孔(11)的周向设置；密封件(3)，用于密封通孔(11)；以及盖体(2)，用于覆盖至少部分密封件(3)，盖体(2)被配置为可旋转的，且包括限位部(22)；其中，在盖体(2)旋转至第一位置时，限位部(22)位于容纳部(12)内以限制盖体(2)与端盖(10’)分离；在盖体(2)旋转至第二位置时，限位部(22)与容纳部(12)沿通孔(11)的周向错位，以实现盖体(2)与端盖(10’)的分离。
