Abstract
Provided are a seal tape and a secondary battery. The seal tape for adhering an electrode assembly includes a pressure-sensitive adhesive layer including a cured product of a pressure-sensitive adhesive composition including a polymer including a polar functional group-containing monomer as a polymerization unit, and is expanded in contact with an electrolyte solution to be detached from the electrode assembly, and therefore, isotropic volume expansion and contraction of the electrode assembly may be induced by repeated charging and discharging of a secondary battery and a disconnection phenomenon in which an electrode is disconnected may be prevented.
