The invention provides a cylindrical battery cell, a battery pack, a vehicle, and a collector plate. The cylindrical battery cell includes: a winding core type electrode assembly having a structure in which a first electrode plate and a second electrode plate, each of which is sheet-shaped, are wound in one direction with a separator interposed therebetween, the first electrode plate including a first non-coated region not coated with an active material layer at an end portion of a long side, and the second electrode plate including a second non-coated region not coated with an active material layer at an end portion of a long side; the first non-coated region forms a plurality of winding turns with respect to the center of the electrode assembly and is exposed to the outside of the diaphragm so as to itself serve as an electrode tab; a battery can having an opening portion accommodating the electrode assembly and a partially closed portion provided on an opposite side of the opening portion, the battery can being electrically connected to the second electrode plate; a collector plate electrically connected to the first non-coated region of the first electrode plate and having a fusing portion that is cut off when an overcurrent flows; and a battery cell terminal connected to the collector plate through the through hole of the closure portion of the battery can.

    本发明提供圆柱形电池单元、电池组、车辆和集流板。所述圆柱形电池单元包括:卷芯型电极组件,该电极组件具有其中均为片状的第一电极板和第二电极板夹着隔膜沿一个方向卷绕的结构,第一电极板包括在长边的端部处没有涂覆活性材料层的第一非涂覆区,第一非涂覆区相对于电极组件的中心形成多个卷绕匝并暴露于隔膜的外部从而本身用作电极接头;电池罐,该电池罐具有容纳电极组件的开口部和设置在开口部的相对侧的部分闭合部,电池罐与第二电极板电连接;集流板,该集流板与第一电极板的第一非涂覆区电连接,并具有熔断部,该熔断部在过电流流动时被切断;以及电池单元端子,该电池单元端子穿过电池罐的闭合部的通孔与集流板连接。
