The invention discloses a cylindrical battery, a battery pack comprising the cylindrical battery and an automobile. The cylindrical battery includes: an electrode assembly including first and second uncoated portions defined as electrode tabs; a battery case that accommodates the electrode assembly through an open portion formed on one side and is electrically connected to the second uncoated portion; an electrode terminal crimped through a through-hole formed in a closed part provided on the opposite side of the open part of the battery case, the electrode terminal being electrically connected to the first uncoated part; an insulating gasket sandwiched between the electrode terminal and the through hole; and a cover plate that covers the opening of the battery case. The electrode terminal includes: a main body portion inserted into the through hole; an outer flange part extending along the outer surface of the sealing part from one side of the main body part exposed through the outer surface of the sealing part of the battery case; an inner flange portion extending from the other side edge of the main body portion exposed through the inner surface of the closing portion toward the inner surface; and a flat portion provided on the inner side of the inner flange portion.

    圆筒形电池、包括该圆筒形电池的电池组及汽车。圆筒形电池包括:电极组件,其具备作为电极极耳而定义的第一及第二无涂层部;电池外壳,其通过形成于一侧的开放部而收纳电极组件并与第二无涂层部电连接;电极端子,其通过形成于封闭部的通孔而铆接,并与第一无涂层部电连接,封闭部设置在电池外壳的开放部的相反侧;绝缘垫圈,其夹在电极端子与通孔之间;盖板,其覆盖电池外壳的开口部。电极端子包括:主体部,其插入到通孔;外部凸缘部,其从通过电池外壳的封闭部的外表面而露出的主体部的一侧边围沿着封闭部的外表面而延伸;内部凸缘部,其从通过封闭部的内表面而露出的主体部的另一侧边围朝向内表面而延伸;平坦部,其设置于内部凸缘部的内侧。
