The invention provides a cylindrical battery, a current collector applied to the cylindrical battery, a battery pack comprising the cylindrical battery and an automobile. The current collector may include: an annular portion surrounding a central axis of the electrode assembly so as to define an opening region in which an electrode tab composed of an uncoated portion is exposed at one end of the electrode assembly; a tab coupling portion extending from the inside of the annular portion adjacent to the opening region toward the opening region and coupled to the electrode tab exposed through the opening region; and a case coupling part that extends from the outside of the annular part toward the inner peripheral surface of the battery case and that is coupled to the battery case.
本发明提供圆筒形电池及应用于其的集电体、包括其的电池组及汽车。上述集电体可以包括:环状部,其包围上述电极组件的中心轴边围,以便能够定义在上述电极组件的一侧端部露出由无涂层部构成的电极极耳的开口区域;极耳结合部,其从与上述开口区域相邻的环状部的内侧朝上述开口区域延伸,并且与通过上述开口区域露出的上述电极极耳结合;以及壳体结合部,其从上述环状部的外侧朝上述电池壳体的内周面延伸,并且与上述电池壳体结合。
