Cylindrical battery cell, battery pack, vehicle and current collector plate

A cylindrical battery cell, comprising:

• an electrode assembly having a first electrode plate and a second electrode plate, each having a sheet shape, being wound in one direction with a separator being interposed therebetween, the first electrode plate including a first uncoated region in which an active material layer is not coated at an end of a long side of the first electrode plate, the first uncoated region forming a plurality of winding turns with respect to a center of the electrode assembly and being exposed beyond the separator;
• a battery can having an open portion in which the electrode assembly is accommodated therein and a partial closed portion provided at a side opposite the open portion, the battery can being electrically connected to the second electrode plate, the partial closed portion having a through-hole;
• a current collector plate electrically connected to the first uncoated region of the first electrode plate and having a fusing portion that is configured to be cut off when an overcurrent flows;
• and
• a cell terminal connected to the current collector plate through the through-hole of the closed portion of the battery can.
