  "textContent": "A secondary battery includes an electrode assembly having a positive electrode, a negative electrode, a separator interposed therebetween, a positive electrode tab, and a negative electrode tab; a cap assembly having a current interrupt device to interrupt current when pressure increases, a safety vent connected to an upper end of the current interrupt device, and a top cap with an upwardly protruding shape; and a battery case to receive the electrode assembly and the cap assembly therein. The battery case has an inner layer adjacent to the electrode assembly and an outer layer of a material exhibiting lower thermal conductivity than the inner layer. The inner layer and the outer layer having a welding portion, at which only the predetermined regions of the inner layer and the outer layer are fixed.",
