Electrode Assembly, Cylindrical Battery Cell, And Battery Pack And Vehicle Including Same

Abstract: The present invention provides an electrode assembly, a cylindrical battery cell, and a battery pack and a vehicle including the same. An electrode assembly of the present invention corresponds to a jelly-roll type electrode assembly having a structure in which a first electrode current collector and a second electrode current collector having a sheet shape and a separator interposed therebetween are wound in one direction, wherein the first electrode current collector includes a first uncoated portion at a long side end portion on which an active material layer is not coated, and the first uncoated portion is exposed to the outside of the separator while forming a plurality of winding turns on the basis of the center of the electrode assembly to be used itself as an electrode tab, and includes an insulation member for covering an exposed curved surface of the first uncoated portion positioned at an outermost winding turn exposed through an outer circumferential surface of the electrode assembly among the plurality of winding turns.
