Cylindrical Battery Cell, Battery Pack And Vehicle Including Same, And Current Collector Plate

Abstract: A cylindrical battery cell, a battery pack and a vehicle including same, and a current collector plate are disclosed. The cylindrical battery cell according to one embodiment of the present invention comprises: an electrode assembly structured such that a positive electrode plate, a negative electrode plate, and a separator interposed between the positive electrode plate and the negative electrode plate are wound in one direction; a cylindrical battery can in which the electrode assembly is accommodated and which has a through hole; a positive electrode current collector plate electrically connected to the positive electrode plate; a cell terminal connected to the positive electrode current collector plate through the through hole of the battery can; and a negative electrode current collector plate electrically connected to the negative electrode plate, wherein the positive electrode current collector plate or the negative electrode current collector plate has a fracture-inducing portion so that at least a portion of the positive electrode current collector plate or the negative electrode current collector plate is fractured by gas generated in the battery can.
