PROBLEM TO BE SOLVED: To provide a corrosion resistant tube for a secondary battery including a volatile corrosion inhibitor (VCI) and a base resin, and a secondary battery including the same.SOLUTION: A corrosion resistant tube comprises: at least one volatile corrosion inhibitor selected from NaNO2 and NaNO3; and a polymer resin selected from among polypropylene, polybutylene terephthalate, polyethylene Teflon (R), rayon, nylon, or the like. By coating the corrosion resistant tube on the surface of a metal can, the occurrence of rust or corrosion in a battery cell can be prevented, and therefor, safety of a battery can be improved.SELECTED DRAWING: Figure 1b |
