Cylindrical battery cell having heat-shrinkable tube comprising ultraviolet stabilizer
Disclosed is a cylindrical battery cell in which a heat-shrinkable tube wraps an outer surface of a cylindrical case of the cylindrical battery cell except electrode terminals, the heat-shrinkable tube including: a base material, which is a polyester resin, capable of shrinking by heat; a supplement, which is a nylon resin, capable of increasing a tensile strength and operating temperature of the heat-shrinkable tube; and an ultraviolet stabilizer capable of inhibiting a chain reaction of free radicals generated by cleavage of polymer chains of the nylon resin or the polyester resin, when the heat-shrinkable tube is exposed to an ultraviolet ray irradiation.
