Kind Code:
A1
Abstract:
Disclosed are a cylindrical battery cell, and a battery pack and a vehicle comprising same. The cylindrical battery cell is a jelly roll-type electrode assembly having a structure in which a first electrode plate and a second electrode plate which have a sheet shape, and a separator which is interposed therebetween are wound in one direction, wherein the first electrode plate includes a first non-coated portion which is not coated with an active material layer at a long side end thereof, and the first non-coated portion includes: an electrode assembly which is exposed to the outside of the separator and is used as an electrode tab itself while forming a plurality of winding turns on the basis of the center of the electrode assembly; a battery can which has an open portion in which the electrode assembly is accommodated and a partially closed portion on the opposite side of the open portion, and which is electrically connected to the second electrode plate; a current collector plate which is electrically connected to the first non-coated portion of the first electrode plate and has a fusing portion which is cut off when an overcurrent flows; and a cell terminal which is connected to the current collector plate through a through hole of the closed portion of the battery can.
