Abstract

本申请提供一种二次电池、电池模块以及使用二次电池作为电源的装置。二次电池包括：壳体；电极组件，设于壳体内，其包括主体部和极耳；顶盖组件，包括连接于壳体的顶盖板和设于顶盖板的电极端子；集流构件，包括转接片和连接件，连接件与转接片分开提供并相互连接，转接片与电极端子连接，转接片包括导引段，导引段位于主体部沿二次电池的长度方向一侧且沿垂直长度方向的方向延伸；连接件包括用于连接导引段的集流段和用于连接极耳的极耳连接段，集流段设于导引段和主体部之间，连接件的刚度小于导引段的刚度，以使连接件与极耳连接的部分相对于长度方向折弯时，能减小导引段朝主体部的变形，降低导引段挤压极片而导致极片脱膜或掉粉的可能性。
