  "textContent": "A cylindrical secondary battery includes a jelly-roll type electrode assembly, a cylindrical battery case for receiving the jelly-roll type electrode assembly, and a cap assembly mounted to the open upper end of the cylindrical battery case. The jelly-roll type electrode assembly includes a long sheet type positive electrode and a long sheet type negative electrode wound with a separator interposed between the positive electrode and the negative electrode. A welding pole is formed on the bottom surface of the cylindrical battery case so as to extend perpendicularly thereto.",
