Abstract

The present invention relates to a cylindrical battery cell having a heat-shrinkable tube wrapping around an outer surface of a cylindrical case excluding electrode terminal portions, wherein the heat-shrinkable tube comprises: a tube base made of a polyester-based resin having heat shrinkability; a reinforcing agent made of a nylon resin for increasing the tensile strength and use temperature of the heat-shrinkable tube; and an ultraviolet absorber which absorbs ultraviolet rays irradiated to the heat-shrinkable tube and emits the ultraviolet rays as heat energy, thereby preventing polymer chains of a nylon-based resin or a polyester-based resin from reacting with oxygen to cause a decomposition reaction.
