1. A secondary battery having a jelly roll type electrode assembly (‘jelly roll’) of a cathode/separator/anode structure mounted in a battery container, wherein a seal tape is attached to an outer side of the jelly roll comprising a wound end of the jelly roll, and the seal tape reacts with an electrolyte with the result that the seal tape is gelled,
wherein the seal tape comprises a tape-shaped film substrate and an adhesive layer applied to a side of the film substrate contacting the jelly roll, and the film substrate is gelled, and wherein, when the seal tape is impregnated with the electrolyte, a physical property of the film substrate is changed into a form exhibiting adhesiveness. |
