Abstract

一种端盖组件(40)、二次电池(30)、电池模块(20)、装置、注液方法及注液装置。端盖组件(40)用于二次电池(30)，其包括：端盖(50)，设有用于注入电解液的通孔(50a)，端盖(50)具有连接部(51)。密封组件(60)，用于密封通孔(50a)。锁固件(70)，被配置为沿通孔(50a)的径向相对于连接部(51)可移动，以用于实现锁固件(70)与连接部(51)在锁定状态和解锁状态切换，在锁定状态时，锁固件(70)抵压密封组件(60)以限制端盖(50)与密封组件(60)分离。在解锁状态时，端盖(50)与密封组件(60)可分离，以允许从通孔(50a)注入电解液。二次电池(30)在完成组装后，也可以再次补充电解液，有效延长二次电池(30)的使用寿命。
