| description | Disclosed are an electrode assembly, a cylindrical battery cell and a battery pack and a vehicle comprising the same. A jellyroll type electrode assembly has a structure in which a first electrode current collector and a second electrode current collector, each having a sheet shape, are wound in a direction with a separator interposed between, wherein the first electrode current collector includes a first uncoated region in which an active material layer is not coated at an end of a long side, the first uncoated region forms a plurality of winding turns with respect to a center of the electrode assembly, is exposed through the separator, and is used as an electrode tab per se, and the electrode assembly comprises an insulation member which covers an exposed curved surface of the first uncoated region disposed at an outermost winding turn exposed through an outer circumferential surface of the electrode assembly among the plurality of winding turns. |
